Verb forms 施工

Present / future

Use for habits, general facts, and future actions. Context tells you when.

Past

Describe an action or event that has already happened. Compare the affirmative and negative forms below.

Te-form

Connect this action to another clause or grammar pattern. The te-form does not express tense by itself.

If · ば

State a condition with ば. The rest of the sentence describes what follows if that condition holds.

Potential

Say that someone can do something, whether through ability or because the situation allows it.

Passive

Put the person or thing affected by an action at the center of the sentence.

Causative

Say that someone makes or lets another person do something. Context distinguishes permission from force.

Causative-passive

Say that someone is made to do something by another person.

Volitional

Suggest doing something together, or express an intention to act. Often translated as “let’s” or “I’ll”.

Imperative

Give a direct command. These forms can sound forceful; use てください for an ordinary polite request.
