How to distinguish between ichidan (ru-verb) and godan (u-verb).
Here’s a simple rule: if a verb’s dictionary form does not end in eru or iru, it is definitely an u verb. If it ends in eru or iru, it can be either a ru verb or an u verb.
Examples of u-verbs (godan) :
- 書く kaku (write)
- 読む yomu (read)
- 売る uru (sell)
- とる toru (take)
- なる naru (become)
