Beginner Grammar初級

[Noun/Adjective] です

です (desu) is the polite form of the copula, equivalent to 'is/am/are' in English. It is placed at the end of a sentence to make it polite. It can follow nouns and na-adjectives.

[Topic] は [Comment]

The particle は (pronounced 'wa') marks the topic of the sentence — the thing you are talking about. It sets up the context and is followed by a comment about the topic.

[Subject] が [Predicate]

The particle が marks the grammatical subject of a sentence. It identifies who or what performs the action or is described. Use が when introducing new information or when the subject is the focus.

[Statement] か

Adding か (ka) to the end of a sentence turns it into a question. In polite speech, the intonation rises naturally. No need to change word order like in English.

[Object] を [Verb]

The particle を (pronounced 'o') marks the direct object of a verb — the thing that receives the action. It connects the object to the verb that acts on it.

[Place/Time] に [Verb]

The particle に has several uses: marking the destination of movement, the time of an action, or the location where something exists.

[Place] で [Action Verb] / [Means] で [Verb]

The particle で marks where an action takes place or the means/tool used to do something. Unlike に, which marks existence location, で marks the location of active events.

[Noun A] の [Noun B]

The particle の connects two nouns, indicating possession, description, or a modifying relationship. It works like 's in English or 'of' in reverse order.

[Verb stem] + ます

The ます (masu) form is the polite present/future tense of verbs. It is used in formal speech and is usually the first verb form taught to beginners. The negative is ません, past is ました, past negative is ませんでした.

[Verb て-form] + ください / います

The て-form (te-form) is one of the most important verb conjugations in Japanese. It connects verbs, makes requests (〜てください), and forms progressive tense (〜ています).

[Thing] が [Place] に いる/ある

いる (iru) and ある (aru) both mean 'to exist' or 'there is.' Use いる for living things (people, animals) and ある for non-living things (objects, plants, concepts).

[い-Adjective] + Noun / [い-Adjective] です

い-adjectives (i-adjectives) end in い and can directly modify nouns or stand alone as predicates. They conjugate by changing the い ending.

[な-Adjective] な Noun / [な-Adjective] です

な-adjectives (na-adjectives) require な when modifying a noun directly. When used as a predicate, they are followed by です. They don't end in い (with a few exceptions like きれい and 有名).

[Start] から [End] まで

から means 'from' (starting point) and まで means 'until/to' (ending point). They can be used for time, place, or range.

[Verb stem] + たい

〜たい expresses the speaker's desire to do something. It conjugates like an い-adjective. It is only used for the speaker's own desires (first person), not for others.
