About 10 minutes · written and reviewed by Haruki Yamamoto

Section 1 of 3

Build the volitional from verb type

The volitional form means “let’s,” “shall,” or “I will,” depending on context. Ichidan verbs usually replace る with よう. Godan verbs change the final sound to the o-row plus う. する becomes しよう.

    食べる → 食べよう

    eat → let’s eat / I will eat

    For ichidan verbs, replace る with よう.
