Sentence explanations

1. グループプロジェクトのために学習室を予約したいです。

   I'd like to reserve a study room for a group project.

   グループプロジェクト

   group project

   のために

   for; for the purpose of

   学習室

   study room

   予約したいです

   would like to reserve

   More detail

   グループプロジェクト means “group project.” It is a noun phrase: グループ (“group”) modifies プロジェクト (“project”). Japanese commonly places a modifying noun before the noun it describes, as in 英語の授業 (“English class”), though this particular phrase uses a direct compound rather than の. のために marks purpose here: “for” or “for the purpose of.” In this sentence, グループプロジェクトのために means “for a group project.” The pattern Nのために can express doing something for a purpose: 試験のために勉強します。 means “I study for an exam.” 学習室 means “study room.” It is a compound noun: 学習 means “study” or “learning,” and 室 means “room.” The compound identifies a room intended for studying; 部屋 is the more general word for “room.” 予約したいです expresses “would like to reserve.” The verb is 予約する, “to reserve” or “to make a reservation.” Its polite nonpast form is 予約します; replacing the polite ending with the desiderative form gives 予約したい, “want to reserve,” and です adds polite sentence-final style: 予約したいです. The たい form usually expresses the speaker’s desire, so the fixed translation naturally uses “I’d like to.” For example, 水を飲みたいです。 means “I’d like to drink water.” Together, グループプロジェクトのために gives the purpose, 学習室を marks the study room as the object, and 予約したいです says that the speaker would like to reserve it. Japanese does not state the subject explicitly here; the fixed translation identifies the intended subject as “I.” The complete meaning is “I’d like to reserve a study room for a group project.”

2. どのくらいの広さの部屋が必要ですか。

   What size room do you need?

   どのくらい

   how much; to what extent

   広さ

   size; area

   部屋

   room

   必要ですか

   do you need it?

   More detail

   どのくらい asks about degree or amount. With a noun through の, it forms a reusable pattern: どのくらいの + noun = “what … / how much ….” For example, どのくらいの時間が必要ですか。 means “How much time is needed?” 広さ means “size” or “area” here, specifically the extent of a space. It is the noun formed from 広い “spacious/wide” with さ, which turns a descriptive property into a noun: 広い → 広さ. Thus どのくらいの広さ asks “of what size/area?” 部屋 means “room.” The sequence 広さの部屋 places the size description before the noun: literally, “a room of [that] size.” In the full question, どのくらいの広さの部屋 means “what size room.” 必要ですか is a polite question built from 必要 “necessary/needed,” polite です, and question marker か. In this context, the understood item is the room being arranged, so the intended meaning is “do you need [a room]?” The form ですか makes the statement a polite question; it does not itself specify a quantity. Combining the parts gives どのくらいの広さの部屋 “a room of what size” plus 必要ですか “is needed?/do you need it?” Japanese places the size description before 部屋, producing the natural meaning “What size room do you need?”

3. いつ使いたいですか。

   When do you want to use it?

   いつ

   when

   使いたい

   want to use

   More detail

   いつ asks about time: “when?” It can be used for a point or period without changing form. Example: いつ来ますか。 = “When will you come?” 使いたい means “want to use” here. It is built from 使う (“to use”) plus たい, a form that expresses the speaker’s or, in a question, the addressee’s desire: 使う → 使いたい. The たい form behaves like a descriptive predicate; for example, 食べたいです。 means “I want to eat.” The final ですか makes the utterance a polite question. Japanese commonly leaves participants and objects unspoken when context makes them understood. Here, the fixed translation identifies the addressee as the person whose desire is being asked about and the object as “it”; the sentence itself does not state those words. Together, いつ + 使いたい + ですか asks politely, “When do you want to use it?” The time question comes first, followed by the desire to use the understood object and the polite question ending.

4. 私たちは今日の午後、4人で使える静かな部屋が必要です。

   We need a quiet room this afternoon for four people.

   私たちは

   we

   今日の午後

   this afternoon

   4人で

   for four people

   使える

   can be used

   静かな

   quiet

   部屋

   room

   必要です

   is needed

   More detail

   私たちは means “we” and marks the topic with は. 私たち is the first-person plural pronoun; unlike English, Japanese often omits such pronouns when the context is clear. Here it identifies the people who need the room. 今日の午後 means “this afternoon.” The の links 今日 (“today”) and 午後 (“afternoon”): the first noun specifies the second. The same pattern is reusable in expressions such as 明日の朝 (“tomorrow morning”). 4人で means “with four people” or, in this sentence, “for four people.” The counter 人 counts people, and で marks the group or arrangement involved in an action or situation. Here it combines with 使える to describe a room usable by a group of four; it does not by itself assert that four people are currently present. 使える is the non-past potential form of 使う (“to use”), meaning “can use” or “usable.” Its ending -える expresses ability or usability for this verb. In 4人で使える部屋, the whole clause 4人で使える comes before 部屋 and describes the room: “a room that four people can use.” This form is different from 使う, which simply means “use.” 静かな means “quiet” before a noun. Its base form is the na-adjective 静かだ; before a noun, だ changes to な, giving 静かな部屋 (“a quiet room”). For example, 静かな場所 means “a quiet place.” 部屋 means “room.” In this sentence it is the noun modified by both 4人で使える and 静かな: it is a room that four people can use and that is quiet. Japanese normally places these modifiers before the noun they describe. 必要です means “is needed” or “need.” 必要 is a na-adjective/noun expressing necessity, and です is its polite non-past form. The construction Nが必要です means “N is necessary”; with the topic structure here, 私たちは部屋が必要です means “As for us, a room is needed,” naturally translated as “We need a room.” 必要です is not the verb “need” itself; it states that something is necessary. Putting the parts together: 私たちは sets “we” as the topic, 今日の午後 specifies the time, and 4人で使える静かな部屋 identifies the needed item as “a quiet room that four people can use.” 必要です completes the polite statement: “We need a quiet room this afternoon for four people.”

5. 今日の午後、2時間使える部屋が一つ空いています。

   There is one available for two hours this afternoon.

   今日の午後

   this afternoon

   2時間

   two hours

   使える

   can be used

   部屋

   room

   一つ

   one

   空いています

   is available

   More detail

   今日の午後 means “this afternoon.” 今日 means “today” and 午後 means “afternoon”; together they make a time expression at the beginning of the sentence. A similar pattern is 明日の朝 (“tomorrow morning”). 2時間 means “two hours.” 時間 measures a duration of time, so here it specifies how long the room can be used. For example, 3時間使えます means “It can be used for three hours.” 使える means “can be used” here. Its base verb is 使う (“use”), and 使える is its plain non-past potential form. Used before a noun, it describes something that can be used: 使える部屋 means “a room that can be used.” This is a possibility or suitability statement, not an instruction. 部屋 means “room.” In 2時間使える部屋, it is the noun described by the preceding clause: “a room that can be used for two hours.” 一つ means “one” when counting a general object. つ is a general-purpose counter; people, for example, are counted with 一人, not 一つ. Here 一つ counts one available room. 空いています means “is available” here. Its base verb is 空く, “to become vacant” or “to become available.” The ている form presents the resulting available state politely. This differs from 開いています, which commonly describes something being open, such as a door or shop. The sentence combines 今日の午後 (“this afternoon”) + 2時間使える部屋 (“a room that can be used for two hours”) + が一つ (“one [such room]”) + 空いています (“is available”). The whole utterance means: “There is one room available for two hours this afternoon.”

6. それなら、スライドを見直して、それぞれの部分を誰が発表するか決める時間が十分あります。

   That gives us enough time to review the slides and decide who will present each part.

   それなら

   in that case; then

   スライド

   slides

   見直して

   review; look over again

   それぞれ

   each; respectively

   部分

   part; section

   誰が

   who

   発表する

   present

   決める

   decide

   時間

   time

   十分

   enough; sufficient

   あります

   there is; is available

   More detail

   それなら means “if that is the case” or “then,” linking this sentence to the preceding situation. それ refers to the established situation, while なら presents that situation as the basis for the conclusion that follows. スライド is the noun “slide,” written in katakana as a loanword. With を, スライドを marks the slides as the object of 見直す. 見直して is the て-form of 見直す, “to review” or “to look over again.” Here the て-form links reviewing with the following decision: 見直して、決める means “review and decide.” It does not itself mark past time. それぞれ means “each” or “respectively,” distributing attention individually. In それぞれの部分, it combines with の to mean “each part.” 部分 means “part” or “section.” In それぞれの部分を誰が発表するか, 部分を marks each part as the object of 発表する within the embedded question, not as the object of 決める. 誰が means “who” as the subject of an embedded question. The particle が marks the person performing the action, so 誰が発表するか means “who will present.” This contrasts with 誰を, where を marks a person as an object. 発表する is the dictionary form of “to present” or “to give a presentation.” Its nonpast form is used here inside the embedded question before か; the time is understood from the situation rather than marked as past. The subject is 誰が, meaning “who.” 決める means “to decide” or “to determine.” The clause 誰が発表するか comes before 決める and functions as what is decided: “decide who will present.” Japanese commonly places an embedded question directly before the verb that applies to it. 時間 means “time.” With が, 時間が marks the time as what is available or exists in the sentence. No numerical amount is stated; sufficiency is expressed by 十分. 十分 means “enough” or “sufficient.” In 時間が十分あります, it says that the available time is sufficient. A related pattern is 十分な時間, “sufficient time,” where 十分な directly modifies the noun. あります is the polite nonpast form of ある, used for the existence or availability of an inanimate thing. Here it says that sufficient time is available. The polite form fits ordinary respectful conversation. Together, それなら introduces a conclusion based on the established situation. スライドを見直して expresses reviewing the slides, and それぞれの部分を誰が発表するか決める expresses deciding who will present each part. 時間が十分あります says that enough time is available for these activities. The whole utterance means: “That gives us enough time to review the slides and decide who will present each part.”

7. あなたの図書館アカウントで予約します。

   I'll reserve it under your library account.

   あなたの

   your

   図書館

   library

   アカウント

   account

   で

   with; using

   予約します

   reserve; book

   More detail

   あなたの means “your.” The ending の links a possessor to the noun that follows: あなたの図書館 means “your library.” あなた is the ordinary second-person pronoun “you,” and の marks the relationship here; it does not itself express a number. 図書館 means “library.” It is a noun and can be combined with other nouns in a compact noun phrase, as in 図書館アカウント, “library account.” アカウント is the loanword “account.” In this utterance it refers to the account used for the reservation. Together, あなたの図書館アカウント means “your library account.” で marks the means or service through which an action is carried out here: あなたの図書館アカウントで means “using your library account” or “under your library account.” The same particle can have other functions in other sentences, so its contribution is determined by the surrounding phrase and verb. 予約します means “will reserve” or, in the intended translation, “will reserve it.” 予約 is the noun “reservation” or “booking,” and する is the verb “to do”; 予約する is the reusable compound verb “to make a reservation.” します is the polite nonpast form of する, so 予約します is the polite form of 予約する. Japanese nonpast forms can describe a future action when the context does so. The subject is omitted in the Japanese sentence; the fixed translation supplies the intended first-person subject “I,” and the object corresponding to “it” is also understood rather than stated. The pattern is [person’s] [service/account]で [action]します: the first part identifies whose account is involved, で marks the means or account used, and 予約します states the polite reservation action. Thus あなたの図書館アカウントで予約します means “I’ll reserve it under your library account.”

8. 予定が変わったら、オンラインで予約をキャンセルできます。

   You can cancel online if plans change.

   予定

   plans; schedule

   変わったら

   if plans change

   オンラインで

   online

   予約

   reservation; booking

   キャンセルできます

   can cancel

   More detail

   予定 means a plan or schedule. Japanese nouns do not normally mark singular versus plural, so this can correspond to “a plan,” “plans,” or “the schedule” when context supplies that reading. Here, the fixed translation supports “plans.” 変わったら comes from 変わる (“to change”). The observed form combines the past form 変わった with ら to make a condition: “if/when it changes.” The subject is not repeated in Japanese; in this sentence, the intended subject is the plans or schedule expressed by 予定が. Compare the related conditional pattern 変われば, which is another conditional form, while 変わったら presents the change as a condition that occurs. オンラインで means “online.” The particle で marks the means or setting used for an action. For example, オンラインで申し込む means “apply online.” 予約 means a reservation or booking. It is a noun here and is marked by を as the object of the following action. It can also appear in the useful verb-like compound 予約する, “to make a reservation” or “to book.” キャンセルできます means “can cancel.” キャンセルする is the verb “to cancel,” and できます is the polite non-past form of できる, expressing ability or possibility. In this sentence, the cancelable object is 予約: 予約をキャンセルできます means “you can cancel the reservation.” The polite ending makes the statement suitable for a service or instruction context. The structure is 予定が変わったら (“if plans change”) + オンラインで (“online”) + 予約をキャンセルできます (“you can cancel the reservation”). Together: “You can cancel online if plans change.” The Japanese condition comes first, followed by the available action.

9. 私たちはこのカウンターで鍵を受け取りますか。

   Do we pick up the key at this desk?

   私たちは

   we

   この

   this

   カウンター

   counter; desk

   で

   at; in

   鍵

   key

   を受け取ります

   pick up; receive

   か

   question marker

   More detail

   私たちは means “we” as the topic. 私たち is a first-person plural pronoun; は marks what the question is about. Japanese does not require this form to specify whether the listener is included. この means “this” and is a demonstrative placed before the noun it describes. Here it identifies the counter as the one intended by the fixed translation. Related forms include その “that near you” and あの “that over there.” カウンター is a loanword meaning “counter” or “desk” in this setting. It is a noun, so このカウンター forms the noun phrase “this counter/desk.” で marks the place where an action occurs. Thus このカウンターで means “at this counter.” This differs from に, which commonly marks a destination or the location where something exists; で focuses here on the action of receiving. 鍵 means “key.” The particle を after it marks it as the direct object: the thing being received. 鍵を therefore means “the key” as the object of the following verb. 受け取ります is the polite nonpast form of 受け取る, “to receive” or “to pick up.” The nonpast form can describe a present or future action depending on context, so in this question it asks whether the speakers will pick up the key. The polite ending makes the question suitable for a service interaction. For example, 荷物を受け取ります。 means “I will receive the package” or “I receive the package,” depending on context. か at the end turns the preceding statement into a question. With the rising or questioning intonation typical of speech, 受け取りますか asks “Will [someone] receive/pick up it?” Here the subject is supplied by 私たちは, so the meaning is “Do we pick it up?” Putting the parts together: 私たちは sets “we” as the topic, このカウンターで gives the place of the action, and 鍵を受け取りますか asks whether we receive or pick up the key there. The complete meaning is “Do we pick up the key at this desk?”

10. ここで受け取って、次の予約が始まる前に返してください。

    Pick it up here, then return it before the next booking starts.

    ここで

    here

    受け取って

    pick up and

    次の

    next

    予約

    booking

    始まる前に

    before it starts

    返してください

    please return it

    More detail

    ここで means “here,” with で marking the place where an action takes place. The location is attached to the action that follows: ここで受け取る means “pick it up here.” For a place where something exists, Japanese commonly uses に instead, as in ここにあります (“It is here”); that is a different pattern. 受け取って is the te-form of 受け取る, “to receive” or “to pick up.” The te-form connects this action to what follows, giving the sequence “pick it up, and then …” here. 受け取る is more specific than simply 取る: it commonly involves receiving or taking possession of something. Example: 荷物を受け取ってください。 — “Please pick up the package.” 次の is the attributive form meaning “next” or “the following.” It comes directly before the noun it describes: 次の予約 means “the next booking.” The same form can describe other nouns, for example 次の電車 (“the next train”). 予約 means “booking” or “reservation.” It is a noun and can combine with する to make the verb 予約する, “to book” or “to make a reservation.” In this utterance, however, 予約 is the noun modified by 次の. 始まる前に means “before [it] starts.” 始まる is the intransitive verb “to begin” or “to start”; its subject is the event that begins, here the next booking. 前に is the reusable pattern “before …,” placed after a clause in the plain form: 始まる前に = “before it starts.” For example, 映画が始まる前に入りましょう。 — “Let’s go in before the movie starts.” 返してください is a polite request meaning “please return it.” It consists of 返す, “to return something,” in its te-form 返して, followed by ください, which makes a polite request. The object is understood from the situation and is not stated in this phrase. 返す is transitive, so a stated object can be marked with を: 本を返してください。 — “Please return the book.” Taken in order, ここで受け取って sets the first action and its place: “pick it up here.” 次の予約が始まる前に sets the deadline: “before the next booking starts.” 返してください gives the polite requested action. Together, the utterance means: “Pick it up here, then return it before the next booking starts.”

11. 私たちは部屋をきれいに使って、時間どおりに出ます。

    We'll keep the room clean and leave on time.

    私たちは

    we

    部屋

    room

    きれいに

    cleanly; neatly

    使って

    use, and then

    時間どおりに

    on time

    出ます

    leave; go out

    More detail

    私たちは means “we” and marks the topic. 私たち is the first-person plural pronoun, and は presents it as the topic; the same topic applies to the actions that follow. Example: 私たちは帰ります。 — “We will go home.” 部屋 means “room.” With を, as in 部屋を, it is the object of 使う: the room is what is used. Example: 部屋を使います。 — “We use the room.” きれいに is the adverbial form of the na-adjective きれい, meaning “clean” or “neat” here. The に form lets it describe how an action is performed, so きれいに使う means “use [something] cleanly/neatly,” with the practical sense of keeping it clean. Example: 机をきれいに使ってください。 — “Please keep the desk clean.” 使って comes from the verb 使う, “to use.” It is the verb’s te-form. Here, the te-form links this action with the following action; it does not by itself always mean that the first action is completed before the next one. In this sentence, the linked actions are using the room cleanly and leaving on time. Example: 部屋を使って、窓を閉めます。 — “I use the room and close the window.” 時間どおりに means “on time” or “as scheduled.” 時間どおり is a fixed expression meaning that something happens according to the planned time, and に marks the timing of the action. Example: 電車は時間どおりに来ます。 — “The train arrives on time.” 出ます comes from 出る, “to leave” or “to go out.” ます is the polite nonpast form; in this context, the fixed translation makes its intended time future or planned: “will leave.” The relevant meaning here is leaving the room, not merely appearing or coming out in some other context. Example: 八時に出ます。 — “I will leave at eight.” Together, 私たちは sets “we” as the topic, 部屋をきれいに使って expresses using the room while keeping it clean, and 時間どおりに出ます expresses leaving on schedule. The whole utterance therefore means: “We’ll keep the room clean and leave on time.”

12. そうすれば、次のグループは待たずに始められます。

    That way, the next group can start without waiting.

    そうすれば

    that way; if so

    次の

    next; following

    グループ

    group

    待たずに

    without waiting

    始められます

    can start

    More detail

    そうすれば means “if that is done” or, naturally here, “that way.” It is built from そう (“so; in that manner”) and the conditional form すれば of する (“do”). This connective presents the preceding action or situation as the condition for the result that follows. 次の means “next” or “following.” 次 means “next; the following one,” and の links it to the noun after it: 次の + noun = “the next [noun].” Here it describes グループ, rather than functioning as a noun by itself. グループ is the noun “group,” written in katakana. In this sentence it is the participant that can begin; the translation identifies it as the next group. 待たずに means “without waiting.” It comes from 待つ (“wait”): its negative ず-form is 待たず, followed by に. The pattern verb-ずに expresses doing something without doing the verb: for example, 朝ご飯を食べずに出かけました。 means “I went out without eating breakfast.” This form is somewhat more formal than the everyday pattern 待たないで. 始められます means “can start” in this sentence. The base verb is 始める (“start; begin”), and its potential form is 始められる (“can start”), here in the polite form 始められます. The potential form presents starting as possible or permitted; it is not the same as the simple form 始めます, “will start” or “starts.” Together, そうすれば sets up the result, 次のグループ identifies the participant, 待たずに says that waiting is omitted, and 始められます says that starting is possible. The whole utterance means: “That way, the next group can start without waiting.”
