Unit 1 - Section 3: Teineigo (Polite Language)

Teineigo — polite language

丁寧語 is the です/ます layer. It is polite to the listener. It is not the same as 尊敬語 (raising the other person) or 謙譲語 (lowering yourself).

Three layers

LayerWho it marksExample
丁寧語Politeness to the listener行きます / 本です
尊敬語The other person’s actionいらっしゃいます
謙譲語The speaker’s action参ります

You can stack them: 参ります is humble + polite. いらっしゃいます is honorific + polite.

Everyday polite choices

  • です/ます for strangers, service, and most classrooms.
  • Plain form (だ/辞書形) with close friends and in diary or news style.
  • Do not mix です at the end with a casual だ in the same sentence without a reason.
これは宿題です。後で出します。
This is homework. I will hand it in later. (consistent です/ます)
先生はもうお帰りになりました。
The teacher has already gone home. (sonkeigo + ます)
