〜ます — Polite Verb Endings (ます・ません・ました)

〜ます

← Back to Unit 3 · Arc 1

Builds on 連用形(ます形)

Meaning

Plain vs ます is a register choice, not a change in meaning: 行いく and 行いきます both mean 'go'. ます is the safe default with anyone you don't know well, in service and workplace settings, and in most writing.

Key sentence

I'll go to Tokyo tomorrow.

Formation

Attaches toFormExample
Attaches to the masu-stem (連用形れんようけい) of any verb 飲のむ → 飲のみ、食たべる → 食たべ、する → し
Non-past stem + ます (affirmative) / ません (negative) 行いきます / 行いきません
Past stem + ました (affirmative) / ませんでした (negative) 行いきました / 行いきませんでした

When: The everyday polite register — default with strangers, customers, teachers, and coworkers, and in formal writing. Switch to plain forms with close friends and family; ます there can sound stiff, but it is never actually wrong.

Variants

〜ませんか — polite invitation — 'won't you ~?' (一緒いっしょに行いきませんか) 〜ましょう ・ ましょう — polite volitional — 'let's ~ / shall I ~' (its own node)

I didn't sleep well last night.
