Vます／ません

Meaning

〜ます is the positive and 〜ません the negative non-past verb form in polite style.

Formation

1. Use the stem before ます: 書きます, 食べます; replace ます with ません for the negative.
2. する → します／しません; 来る → 来ます（きます）／来ません（きません）.

When to use it

Habit or regular action

Politely says what someone usually does or does not do.

Future action

Expresses a plan or future action when used with a time expression.

Important notes

• The Japanese non-past form does not itself separate present and future; context and time words supply the meaning.

Common mistakes

• Do not attach ます to the dictionary form: use 行きます, not 行くます.
• Do not add a separate negative after ません; this form is already negative.
