Sentence explanations

1. 助けが必要です。

   I need some help.

   助け

   help

   必要です

   is needed

   More detail

   助け means “help” here. It is a noun, so it can be used with が in the pattern [thing]が必要です to say that the thing is needed. For example, 水が必要です。 means “I need some water.” This is the same reusable pattern as the fixed sentence. 必要です means “is needed” or, in this sentence, “need.” 必要 is a な-adjective/noun-like word meaning “necessary” or “needed”; です gives the predicate a polite form. The plain counterpart is 必要だ, while 必要です is suitable for polite conversation. The form 必要です itself does not identify who needs something; Japanese commonly omits the subject when it is understood. Here, the fixed translation supplies “I.” The particle が marks what is needed: 助けが = “help” as the needed thing. Thus 助けが必要です。 combines as “Help is needed,” naturally expressed here as “I need some help.” The sentence does not specify an exact amount; “some” is a natural English rendering of the uncounted noun 助け.

2. 水が必要です。

   I need some water.

   水

   water

   が必要です

   is needed; need

   More detail

   水 means “water.” It is a noun and can refer to water as a substance, so it does not by itself specify a particular amount. The translation’s “some” reflects a natural English rendering; the Japanese sentence does not state a numeric quantity. が必要です expresses that something is needed. が marks the thing that is needed, while 必要 means “necessary” or “needed,” and です gives the statement a polite form. The reusable pattern is [needed thing]が必要です, literally “[needed thing] is necessary,” commonly translated as “I need [needed thing]” when the person needing it is understood from context. 必要です is not the verb “need” itself; it describes the item as necessary. Together, 水 + が必要です form 水が必要です: “Water is needed,” naturally “I need some water.” The sentence states a need but does not specify the amount.

3. これが欲しいです。

   I want this one.

   これ

   this one

   欲しい

   want; be desired

   です

   polite sentence ending

   More detail

   これ means “this one” and is a demonstrative pronoun for something relatively near the speaker. It can stand alone as the thing being referred to; it is not restricted to modifying a noun. In the supplied sentence, the fixed translation identifies it as the wanted item. A useful distance contrast is これ “this one” versus あれ “that one over there,” as in the next sentence. 欲しい means “want” in the sense “desire something.” It is an adjective in Japanese, not a verb. Its useful pattern is [thing]が欲しい, where が marks the thing desired. For example, 水が欲しいです。 means “I want water.” This differs from 必要です in the previous sentence, which expresses need or necessity rather than desire. The observed form 欲しい is the non-past form; its negative form is 欲しくない (“do not want” / “is not wanted,” depending on context). です adds a polite sentence ending here. With the adjective 欲しい, it makes the statement polite: 欲しいです means “want it” in a polite style. It does not itself mean “want,” and the desire meaning comes from 欲しい. Together, これが欲しいです。 follows the reusable pattern [desired thing]が欲しいです: これ identifies the desired item, が marks that item, 欲しい expresses the speaker’s desire, and です gives the sentence a polite form. The whole utterance therefore means “I want this one.”

4. あれが欲しいです。

   I want that one.

   あれ

   that one

   欲しい

   want; be wanted

   です

   polite sentence ending

   More detail

   あれ means “that one” and points to something away from the speaker (and typically not the immediately addressed person). In this sentence, the translation identifies the intended referent as one particular item, but the item itself is not named. これ in the preceding sentence provides the useful contrast: これ is “this one,” while あれ is “that one.” The following これは好きです uses これ with a different predicate, so it does not change the meaning of あれ here. 欲しい means “want” in this sentence. Japanese uses this adjective-like form to describe the speaker’s desire for something; it is not the ordinary lexical verb “to want.” Its basic affirmative form is 欲しい, and a useful negative form is 欲しくない, “do not want.” Example: これが欲しくないです。 — “I do not want this one.” です adds polite sentence style. With an adjective such as 欲しい, it makes the statement polite; it does not itself mean “want,” and it does not indicate the item’s number. The form です does not change here to agree with あれ. Together, あれ identifies the desired item, が marks that item in the construction with 欲しい, and 欲しいです politely states the speaker’s desire. The complete meaning is “I want that one.”

5. これは好きです。

   I like this one.

   これ

   this one

   好きです

   like; be fond of

   More detail

   これ means “this one” here. It is a demonstrative pronoun that can stand alone instead of modifying a noun. It is typically used for something near the speaker or treated as speaker-proximal. これ does not inflect for gender or number. Example: これは本です。 means “This is a book.” は follows これ and marks it as the topic, so これは presents “this one” as what the sentence is about. Japanese can leave the person whose preference is being expressed unspoken when that person is understood. Here, the fixed translation identifies that understood person as “I.” 好きです expresses liking or preference in polite style. 好き is a na-adjective, not a lexical verb meaning “like”; です supplies the polite copular ending in this expression. The polite negative counterpart is 好きではありません, as shown in the supplied next sentence. Together, これは and 好きです form the pattern これは好きです, meaning “I like this one.” The topic is “this one,” and the understood experiencer is “I”; Japanese leaves that pronoun unspoken here.

6. それは好きではありません。

   I do not like it.

   それは

   as for it

   好きではありません

   do not like

   More detail

   それは means “as for it” here. それ is a demonstrative pronoun referring to the intended “it”; the supplied translation identifies that referent without specifying what the object is. は marks それ as the topic, so the sentence is organized as “as for it, …”. In the supplied preceding example, これ means “this one,” contrasting with それ, which refers to “that/it” in the current context. The choice between これ and それ depends on the demonstrative system and context, not on whether the object is liked. 好きではありません expresses “do not like” in polite negative form. 好き is a na-adjective-like word meaning “liked” or “fond of”; in Japanese, the liked object is commonly marked with が, although that marker is not present in this sentence because the topic has been marked with は. The polite affirmative pattern is 好きです (“like it / am fond of it”), while 好きではありません negates it politely. Here, ではありません is the polite negative form of the copular pattern; the observed form is not a negative conjugation of a verb meaning “like.” A less formal negative alternative is 好きではない. Together, それは + 好きではありません gives “As for it, [I] do not like [it],” naturally translated as “I do not like it.” Japanese leaves the subject “I” unspoken here; the fixed translation supplies that intended perspective. The sentence is polite and negative.
