   More detail

   나는 means “I” here. It consists of 나 (“I,” the first-person singular pronoun) plus 는, a topic marker used after a vowel. 나 is commonly used in less formal speech; 저 is the humble first-person form used in more formal or deferential situations. The topic marker does not itself mean “one” or add a number. 공부할 때 means “when studying.” 공부하다 means “to study,” and 공부할 is its form before 때 (“time” or “when”), giving the pattern 동사-(으)ㄹ 때 (“when doing ...”). This pattern can describe the time of an activity and is not restricted to a future event. For example, 책을 읽을 때 음악을 들어요. means “I listen to music when I read.” 새 means “new” and appears before the noun it describes. In 새 단어, it describes 단어; 새 is the observed attributive form and should not be treated as an inflected form of the separate word 새롭다. A reusable example is 새 책 (“a new book”). 단어 means “word” or “vocabulary word.” Its plural is often left unmarked when the context makes the quantity clear; a plural marker can be added when needed. For example, 이 단어를 알아요. means “I know this word.” 외워요 comes from the verb 외우다, “to memorize” or “learn by heart.” The ending -어요 creates a polite conversational style; it does not show that the subject is specifically first person. Thus the same ending can be used with other subjects when the context supplies them. Here, 외워요 describes the speaker’s habitual action, so “memorize” is natural; the fixed translation’s “remember” conveys the intended result in English. Together, 나는 sets “I” as the topic, 공부할 때 gives the situation “when studying,” 새 단어 means “new words,” and 외워요 states the action. The complete meaning is “I memorize new words when studying.”

2. 하지만 말하려고 하면 그 단어들을 잊어버려요.

   But I forget them when I try to speak.

   하지만

   But

   말하려고

   to speak

   하면

   when one does

   그

   those

   단어들을

   the words

   잊어버려요

   forget

   More detail

   하지만 introduces a contrast: “but.” It connects this statement with the preceding idea about memorizing new words. A common contrasting conjunction is 그리고 (“and”), but it is not interchangeable here. 말하려고 comes from 말하다 (“to speak”) plus -(으)려고, a pattern for intending or trying to do something. Because 말하다 ends in a vowel, the form is 말하려고, not 말으려고. In this sentence it combines with 하다 in 말하려고 하면, meaning “when/if [I] try to speak.” Example: 한국어를 배우려고 해요. — “I am trying/intending to learn Korean.” 하면 is the conditional or temporal form of 하다 (“to do”), from 하다 + -면. In 말하려고 하면, it does not mean that the speaker is doing a separate, unrelated action; it completes the pattern -려고 하다 (“try/intend to do”) and frames it as “when/if someone tries to do it.” The subject is understood from context rather than stated in this clause. 그 is a demonstrative meaning “that” or “those,” depending on the noun and context. Here it modifies 단어들 and corresponds to “those” in the fixed translation. The surrounding context identifies the topic as the words being remembered and used; the form itself is the demonstrative, not a personal pronoun. 단어들을 is the noun 단어 (“word”) with 들, which can mark a plural group, and the object marker 을. Thus, in this sentence it marks “those words” as what is forgotten. 단어 is singular or plural when no explicit plural marking is needed; 단어들 explicitly presents multiple words, and 을 marks them as the object of the following verb. 잊어버려요 is the polite present form built from 잊다 (“to forget”) with -어 버리다. This pattern presents an action as completed or as an unwelcome result; here the natural meaning is “forget” or “end up forgetting.” The polite ending is -요. Example: 약속을 잊어버렸어요. — “I forgot the appointment.” The observed form is 잊어버려요, while its lexical base is 잊다; 버리다 is part of the result-emphasizing construction here, not the independent meaning “throw away.” Together, 말하려고 하면 means “when I try to speak,” and 그 단어들을 잊어버려요 means “I forget those words.” With 하지만 marking the contrast, the whole utterance is: “But I forget them when I try to speak.”

3. 그 단어들을 실제로 사용할 상황과 연결되어 있지 않을 수도 있어요.

   The words may not be connected to situations where you would actually use them.

   그

   those; the

   단어들을

   words

   실제로

   actually

   사용할

   to use; that you would use

   상황과

   situations with/in relation to

   연결되어 있지 않을 수도 있어요

   may not be connected

   More detail

   그 modifies the following noun and means “those” here. In this sentence, the fixed translation and the surrounding context identify the referent as the words being discussed. Korean demonstratives include 이 “this,” 그 “that/those,” and 저 “that/those over there”; the choice depends on the speaker’s demonstrative system and discourse context, not simply on grammatical number. 단어들을 means “the words” as the object of the clause. Its base noun is 단어 “word,” and 들 marks plural people or things when a plural reading is useful. 을 marks the object, so 그 단어들을 is the set of words affected by the later description. Korean object marking is distinct from the plural marker: 단어를 can mean “the word” or “words” when number is clear, while 단어들을 explicitly presents them as plural. Example: 새 단어들을 외워요. — “I memorize new words.” 실제로 is an adverb meaning “actually” or “in reality.” It emphasizes real use rather than merely knowing or studying the words. Example: 이 표현을 실제로 써 봤어요. — “I actually tried using this expression.” 사용할 comes from the verb 사용하다, “to use.” The ending -ㄹ makes an attributive form referring to a future, intended, or contextually possible action, so 사용할 상황 is “situations in which [one] would use [them].” It does not itself mark a completed or ongoing use. Compare 사용한 상황 “a situation in which [one] used [them]” and 사용하는 상황 “a situation in which [one] uses/is using [them].” 상황과 is 상황 “situation” plus -과, which marks a relation comparable to “with” or “in relation to” in this construction. Together with the following connected-state expression, it identifies the situations to which the words may or may not be connected. -과/-와 is selected according to the final sound of the preceding noun; the choice here is -과 after 상황. 연결되어 있지 않을 수도 있어요 is a possibility-and-negation construction meaning “may not be connected.” 연결되다 is the base verb “to become/be connected”; -어 있다 presents the resulting connected state, -지 않다 negates it, and -(으)ㄹ 수도 있다 expresses possibility. The polite ending -어요 makes the statement polite. The possibility applies to the whole negative state: the words might not be connected to the situations where one would actually use them. Example: 이 정보가 서로 연결되어 있지 않을 수도 있어요. — “This information may not be connected to each other.” As a whole, 그 단어들을 supplies the words under discussion, 실제로 사용할 specifies real situations in which they would be used, and 상황과 연결되어 있지 않을 수도 있어요 says that a connection to those situations may be absent. Thus the utterance means: “The words may not be connected to situations where you would actually use them.”

4. 나는 보통 번역을 적고 나중에 같은 목록을 다시 복습해요.

   I usually write the translation and review the same list later.

   보통

   usually

   번역

   translation

   적고

   write, and

   나중에

   later

   같은

   same

   목록

   list

   다시

   again

   복습해요

   review

   More detail

   보통 means “usually” here. It is an adverb describing how regularly the action happens. A useful contrast is 항상 (“always”) and 가끔 (“sometimes”); these express different frequencies. 번역 means “translation.” It is a noun and can combine with action verbs: 번역을 하다 means “to translate,” while 번역을 적다 means “to write down a translation.” In this sentence, the object particle 을 marks 번역 as what is written. 적고 comes from 적다, “to write” or “to write down,” plus connective -고. The form links this action to the next one; here, 나중에 makes the later sequence clear. The subject is 나는, “as for me/I”; 는 marks the topic. Example: 이름을 적고 서명해요. — “I write my name and sign.” 나중에 means “later” or “afterward.” It places the reviewing action later than the writing action. It does not itself specify exactly when later is. 같은 is the form of 같다, “to be the same,” used before a noun. It describes 목록, so 같은 목록 means “the same list.” The sentence presents the list as one that is the same as a previously identifiable list, without specifying that list further here. Example: 같은 책을 다시 읽어요. — “I read the same book again.” 목록 means “list.” It is the noun inside 같은 목록을; the particle 을 marks it as the object of the reviewing action. 목록 is useful for an ordered collection of items, such as words or tasks. 다시 means “again” or “back.” Here it shows that the list is reviewed another time, not for the first time. Example: 다시 확인해요. — “I check it again.” 복습해요 comes from 복습하다, “to review” or “to study again.” 복습해요 is the polite -해요-style form used in ordinary conversation. The ending makes the statement polite; it does not by itself mean that the reviewing is happening at this exact moment. Example: 저녁에 단어를 복습해요. — “I review vocabulary in the evening.” Together, 나는 보통 번역을 적고 means “I usually write down the translation,” 나중에 places the next action later, and 같은 목록을 다시 복습해요 means “review the same list again.” The complete utterance is: “I usually write the translation and review the same list later.”

5. 유용한 단어마다 간단한 예문을 하나씩 써 보세요.

   Try adding one simple example sentence for each useful word.

   유용한

   useful

   마다

   each; every

   간단한

   simple

   예문

   example sentence

   하나씩

   one each

   써 보세요

   try writing

   More detail

   유용한 means “useful” here and modifies the noun 단어. Its base form is 유용하다 (“to be useful”); the -한 form is the attributive form used before a noun. Example: 유용한 표현 — “a useful expression.” 단어 means “word.” It is a noun, so 유용한 단어 forms the noun phrase “useful word.” Example: 새 단어를 배워요. — “I learn a new word.” 마다 is attached to a noun to express “each” or “every.” Thus 단어마다 means “for each word,” rather than referring to the words as one undivided group. Example: 사람마다 생각이 달라요. — “Each person’s thoughts are different.” 간단한 means “simple” here and modifies 예문. Its base form is 간단하다; 간단한 is the form used before a noun. Example: 간단한 질문 — “a simple question.” 예문 means “example sentence.” It is a noun commonly used for a sentence that demonstrates a word or grammar pattern. Example: 예문을 읽어요. — “I read an example sentence.” 하나씩 expresses distribution: “one each” or “one at a time.” 하나 means “one,” and -씩 marks an equal amount assigned or done per unit. In this sentence, it means one example sentence for each useful word. Example: 사과를 하나씩 드세요. — “Please take one apple each.” 써 보세요 is a polite request meaning “try writing.” 쓰다 is the base form “to write”; before -어, it becomes 써. 보다 after another verb can mean “try doing that action,” and 보세요 makes the request polite. This is different from 쓰세요 (“please write”), which does not explicitly add the idea of trying. Example: 이 문장을 써 보세요. — “Try writing this sentence.” Together, 유용한 단어마다 sets the distribution—“for each useful word”—and 간단한 예문을 하나씩 specifies the object and amount—“one simple example sentence each.” The polite request 써 보세요 completes the utterance: “Try adding one simple example sentence for each useful word.”

6. 일이나 쇼핑, 또는 친구에게 보내는 메시지에 관한 문장을 쓸 수 있어요.

   I can write sentences about work, shopping, or messages to friends.

   일

   메시지

   message

   에 관한

   about; concerning

   문장

   sentence

   쓸

   write

   수 있어요

   can; be able to

   More detail

   일 means work or a job here. It is a noun, and the following 이나—visible in 일이나—links alternatives: 일이나 쇼핑 means “work or shopping.” 이나 is an alternative marker used after a form ending in a consonant; after a vowel, 나 is used. The list is then extended by 또는, meaning “or.” 쇼핑 is the noun “shopping.” It is a borrowed noun commonly used for the activity of shopping. In this sentence, 일이나 쇼핑, 또는 ... presents it as another topic for the sentences the speaker can write. 친구 means friend. In 친구에게, 에게 marks the recipient or target of an action, so the phrase means “to a friend” or, in the plural-compatible meaning supplied by the translation, “to friends.” The noun itself does not indicate whether there is one friend or more than one; that number is not stated by this form alone. 보내는 comes from 보내다, “to send.” The ending -는 makes a present attributive form, which describes a noun: 보내는 메시지 means “messages that [someone] sends” or “messages for sending.” Here it connects 친구에게 with 메시지, giving the intended meaning “messages to friends.” The form 보내는 does not by itself identify the sender. 메시지 means message. Together, 친구에게 보내는 메시지 is a noun phrase referring to messages sent to friends. 메시지 is the noun being described by 보내는; 친구에게 identifies the recipient relationship. 에 관한 means “about” or “concerning.” It follows the noun phrase it describes: 메시지에 관한 means “about messages.” In the full sentence, the larger phrase 일이나 쇼핑, 또는 친구에게 보내는 메시지에 관한 means “about work, shopping, or messages to friends.” 문장 means sentence. In 문장을, the object marker 을 shows that sentences are what the speaker can write. The noun 문장 ends in a consonant, so 을 is used; after a vowel-ending noun, 를 is used. 쓸 comes from 쓰다, “to write.” It is the form 쓰다 combined with -(으)ㄹ, which makes the form used before 수 in the ability construction. The spelling changes to 쓸, not 쓰을. In this sentence, 문장을 쓸 means “write sentences” as part of “be able to write sentences.” 수 있어요 completes the ability construction -(으)ㄹ 수 있다. After 쓸, 쓸 수 있어요 means “can write” or “am able to write.” 있어요 is the polite present form of 있다; in this construction, it expresses that the possibility or ability exists. The polite ending -어요 makes the statement suitable for ordinary polite conversation. Putting the parts together: 일이나 쇼핑, 또는 친구에게 보내는 메시지 lists work, shopping, and messages to friends as topics. 에 관한 문장 means “sentences about” those topics, and 쓸 수 있어요 says that the speaker can write them. Thus the whole utterance means, “I can write sentences about work, shopping, or messages to friends.”

7. 그런 상황을 떠올리면 대화 중에 그 의미를 더 쉽게 기억할 수 있을 거예요.

   Those situations will make the meaning easier to recall during conversation.

   그런

   such; like that

   상황

   떠올리면

   when you think of; when you bring to mind

   대화

   that; the mentioned

   의미

   meaning

   더 쉽게

   more easily

   기억할

   remember

   수 있을 거예요

   will be able to

   More detail

   그런 means “such” or “like that” and describes the kind of thing being discussed. It is a form of 그렇다 used before a noun. With 상황, 그런 상황 means “such a situation” or, as translated here, “those situations.” 상황 is a noun meaning “situation” or “circumstances.” Korean nouns do not normally change form to mark singular versus plural, so 상황 can refer to one situation or to situations more generally; the surrounding meaning supplies the number. 떠올리면 comes from 떠올리다, “to bring to mind” or “to recall.” The ending -면 makes a condition such as “when” or “if”: 떠올리면 is “when you bring it to mind” here. Example: 그 장면을 떠올리면 웃음이 나요. — “When I think of that scene, I smile.” 대화 means “conversation.” It is a noun that can be used in compounds and time expressions, for example 대화 연습 (“conversation practice”). 중에 is used after a noun to mark a period or activity during which something happens. Thus 대화 중에 means “during a conversation.” Example: 수업 중에 질문했어요. — “I asked a question during class.” 그 modifies 의미 and means “the” or “that” in the sense of an already identified meaning. The translation supports “the meaning” here; the form itself does not supply a separate English article system. 의미 means “meaning.” In 그 의미, it is the noun being remembered, while 그 identifies it as the relevant meaning in context. 더 쉽게 means “more easily.” 쉽다 is the base form of the adjective “to be easy,” and 쉽게 is its adverbial form, “easily.” 더 adds comparison, so 더 쉽게 means that the action is easier than before or easier under the stated condition. Example: 이 방법으로 더 쉽게 배울 수 있어요. — “You can learn more easily with this method.” 기억할 comes from 기억하다, “to remember.” The ending -ㄹ makes an attributive prospective form, so 기억할 수 literally has the pattern “the possibility/capacity to remember.” It is not the completed past form; the remembering is presented as something possible in the relevant situation. 수 있을 거예요 completes the pattern -ㄹ 수 있다, “can/be able to,” followed by -을 거예요, which presents an expected or predicted future situation. In this sentence, 기억할 수 있을 거예요 means “will be able to remember.” Example: 내일 만날 수 있을 거예요. — “I will probably be able to meet [you] tomorrow.” Together, 그런 상황을 떠올리면 means “when you bring such situations to mind,” and 대화 중에 specifies the time or setting, “during conversation.” The object 그 의미 is “the meaning,” and 더 쉽게 기억할 수 있을 거예요 says that it will be possible to remember it more easily. The whole utterance therefore means: “Those situations will make the meaning easier to recall during conversation.”

8. 아마 단어를 더 적게 공부하고 더 자주 사용해야겠어요.

   I should probably study fewer words and use them more often.

   아마

   probably

   단어

   word

   더 적게

   fewer; in a smaller amount

   공부하고

   study and

   더 자주

   more often

   사용해야겠어요

   should use

   More detail

   아마 means “probably” here. It marks the speaker’s conclusion as tentative rather than certain. It commonly appears near the beginning of a sentence, as in 아마 내일 올 거예요 (“They will probably come tomorrow”). 단어 means “word.” Its plural is often left unmarked in Korean when the context is clear; 단어들 explicitly presents multiple words. In this sentence, 단어를 is the noun plus the object marker 를, showing that words are what the speaker studies. 더 적게 means “fewer” here: 적다 is the base form meaning “to be few” or “to be small in amount,” and 적게 is its adverbial form. 더 adds comparison, so the phrase means studying a smaller number than before or than an understood alternative. The form describes the amount of 단어, not the words’ quality. For example, 커피를 적게 마셔요 means “I drink less coffee.” 공부하고 comes from 공부하다 (“to study”) plus the connective ending -고. It links studying with the following action as “study and ...”; -고 does not by itself require a “then” interpretation. For example, 읽고 써요 means “I read and write.” 더 자주 means “more often.” 자주 is an adverb meaning “often,” and 더 makes the frequency higher in comparison with an understood previous or alternative level. This modifies the following action, 사용하다, rather than the number of words. 더 자주 만나요 means “We meet more often.” 사용해야겠어요 uses 사용하다 (“to use”) with the pattern -아/어야겠다, here realized as 사용해야겠어요. This pattern presents the speaker’s conclusion or intention that something should be done, giving “I should use [them]” in this context. It is not simply the ordinary present form “I use.” The object is understood from 단어를 and the fixed translation: the words are what should be used. A reusable example is 이제 쉬어야겠어요 (“I guess I should rest now”). Together, 아마 단어를 더 적게 공부하고 sets up the tentative plan to study a smaller number of words, while 더 자주 사용해야겠어요 says that those words should be used more frequently. The whole utterance therefore means: “I should probably study fewer words and use them more often.”

9. 반복해서 사용하면 그 단어들이 실제로 사용할 수 있는 어휘의 일부가 될 거예요.

   Repeated use will help the words become part of your active vocabulary.

   일부

   part

   될 거예요

   will become

   More detail

   반복해서 means “repeatedly” here. It comes from 반복하다 (“to repeat”) in an adverbial form that links this action to what follows: 반복해서 사용하다 = “to use repeatedly.” Example: 이 문장을 반복해서 읽으세요. — “Read this sentence repeatedly.” 사용하면 is 사용하다 (“to use”) plus -면, which presents a condition or a time-triggered situation: “if/when [someone] uses [it].” Korean often leaves the subject unstated when context makes it unnecessary. Example: 매일 사용하면 익숙해져요. — “If you use it every day, you become familiar with it.” 그 is a demonstrative determiner meaning “that” or “the” before a noun. It does not change for number; here it modifies 단어들, translated as “the words.” 단어들이 consists of 단어 (“word”), the plural marker 들, and the subject marker 이. 단어들 means “words,” and -이 marks them as the grammatical subject. Korean can leave number unmarked when context is sufficient, so 단어 can also mean “word” or “words” in another context. 실제로 means “actually” or “in practice.” Here it emphasizes real usability rather than merely theoretical knowledge. Example: 그 방법은 실제로 효과가 있어요. — “That method is actually effective.” 사용할 수 있는 is a relative form meaning “that can be used.” It contains 사용하다 (“to use”) + -(으)ㄹ 수 있다 (“can/be able to”); the final 있는 is the attributive form of 있다 and lets the ability phrase modify a following noun: 사용할 수 있는 어휘 = “vocabulary that can be used.” This is different from 사용하는, which describes using or being in the process of using something, without the same ability meaning. 어휘 means “vocabulary.” Here it occurs in 사용할 수 있는 어휘, referring to vocabulary that can actually be used by the learner. Example: 새 어휘를 문장으로 연습해요. — “I practice new vocabulary in sentences.” 일부 means “part” or “portion.” The pattern 어휘의 일부 uses 의 to connect a whole and a part: “part of the vocabulary.” Example: 이 단어는 중요한 표현의 일부예요. — “This word is part of an important expression.” 될 거예요 comes from 되다 (“to become”) plus -(으)ㄹ 거예요, a polite form commonly used for a prediction or expected future result. 되다 carries the meaning “become”; 거예요 does not mean “part” by itself. Example: 곧 좋은 습관이 될 거예요. — “It will soon become a good habit.” Together, 반복해서 사용하면 sets the condition “when/if [someone] uses [the words] repeatedly.” 그 단어들이 is the subject, followed by 실제로 사용할 수 있는 어휘, “vocabulary that can actually be used.” Finally, 어휘의 일부가 될 거예요 means “will become part of the vocabulary.” The whole utterance means: “Repeated use will help the words become part of your active vocabulary.” It presents repeated use as the condition leading to that expected result.

10. 나는 단어를 몇 개만 골라서 수업 후에 내 생활과 관련된 예문을 쓸게요.

    example sentence(s)

    쓸게요

    I will write

    More detail

    나는 combines 나 (“I”) with the topic marker 는. It presents the speaker as the topic; 나 is the base form, and its possessive form is 내 before a noun. 단어 means “word.” Its plural meaning can be understood from context without a separate plural ending. Example: 새 단어를 배워요. — “I learn new words.” 몇 개만 means “only a few.” 몇 indicates an unspecified small number, and 개 is a general counter for individual items such as words. 만 limits the quantity to that amount. The phrase does not specify an exact number. Example: 몇 개만 골라요. — “Choose only a few.” 골라서 comes from 고르다, “to choose.” The form 골라서 uses -아서/어서 to connect this action to the next one, giving the sequence “choose and then …” or “after choosing …”. 고르다 changes to 골라서 in this form; it is not derived from a separate base 골라. 수업 후에 means “after class.” 후 means “after” or “the time following,” and 에 marks the time when the writing takes place. Example: 수업 후에 복습해요. — “I review after class.” 내 is the contracted possessive form of 나의, meaning “my.” It modifies the following noun. 나 means “I,” while 내 means that something belongs or relates to the speaker. 생활 means “life” or “daily life.” In this sentence, it refers to the speaker’s own life or everyday circumstances, rather than to life in general. Example: 생활이 바빠요. — “My daily life is busy.” 관련된 means “related.” It is the noun-modifying form of 관련되다, “to be related.” Here it modifies 예문, so it describes examples connected with the speaker’s daily life. Example: 이 주제와 관련된 자료 — “materials related to this topic.” 예문 means “example sentence.” It is a useful term for a sentence created to show how a word or pattern is used. Example: 예문을 읽어요. — “I read an example sentence.” 쓸게요 comes from 쓰다, “to write,” plus -(으)ㄹ게요. 쓰다 changes to 쓸게요 because the verb stem ends in a vowel. -(으)ㄹ게요 presents the speaker’s intention or commitment to do something, often with the listener in mind; here it means “I will write.” It is different from simply describing a scheduled future event. Together, 나는 단어를 몇 개만 골라서 means “I will choose only a few words,” with 골라서 linking the choosing to the later action. 내 생활과 관련된 예문 means “example sentences related to my life”: 내 생활 is “my life,” and 과 connects that noun with the relation expressed by 관련된. Finally, 수업 후에 ... 쓸게요 places the writing after class and expresses the speaker’s intention to do it. The whole utterance means: “I will choose a small set and write personal examples after class.”

11. 그 습관을 따르면 어휘 연습이 더 실용적이 될 거예요.

    될 거예요

    should become

    More detail

    그 means “that” and is a demonstrative placed before a noun. Here it specifies 습관, giving 그 습관 “that routine/habit.” Its exact referent is supplied by the fixed meaning, but the form itself does not identify a particular person or object independently. 습관 is a noun meaning a habit or routine. The following 을 in the full sentence marks it as the object of 따르다: 그 습관을 따르다, “follow that routine.” Example: 좋은 습관을 만들어요. — “I form a good habit.” 따르면 comes from the verb 따르다, “to follow,” plus the conditional form -면. The resulting pattern N을/를 따르면 means “if/when [someone] follows N.” The person who follows is understood from context rather than expressed in this form. Example: 이 방법을 따르면 쉬워요. — “If you follow this method, it is easy.” 어휘 is a noun meaning vocabulary, especially the words known or studied in a language. It combines with another noun in 어휘 연습, “vocabulary practice.” 연습 is a noun meaning practice or training. With the subject marker 이 in the full sentence, 어휘 연습이 is the thing described as becoming more practical. Example: 발음 연습을 해요. — “I practice pronunciation.” 더 means “more” and increases the degree of the following description. Here it makes 더 실용적이다 mean “to be more practical,” rather than simply “to be practical.” 실용적 means practical or useful in application. In the sentence, 실용적이 is followed by 되다, so the meaning is “become practical.” The 이 here is part of the form used before 되다; it is not the subject marker attached to 연습. 될 거예요 is the polite form of 되다 (“become”) with -(으)ㄹ 거예요. This construction presents a future expectation or prediction: “will become” or, in this translation, “should become.” The form 되다 is irregular in some other conjugations, such as 돼요, but 될 거예요 uses the future-looking form 될 directly before 거예요. Together, 그 습관을 따르면 sets the condition “if you follow that routine,” and 어휘 연습이 더 실용적이 될 거예요 says that vocabulary practice will become more practical. The complete meaning is: “That routine should make your vocabulary practice more practical.”
