どうしの ふつうけい

The plain form is casual Japanese — what you say with friends. The trick: for each tense you just reach for a form you already know. The orange つくり方column tells you exactly which one — and there's only one new form.

(That's just like the い-adjective たかい → たかかった from Unit 24 — ない behaves like an い-adjective.)

Here are more verbs in all four plain forms. The past-negative column is the new one. 🔊 Tap any form to hear it.

See the ますけい, say all four plain forms in your head, then tap the card to check. Don't forget the new past-negative!

Read the sentence and the English, then choose the correct plain form.
