Examples of the -eru form use ___

____________________

Construction:

It is derived from the dict-form.

Group 1: final "u" becomes "eru"

飲む → 飲める nomu → nomeru

行く → 行ける iku → ikeru

会う → 会えす au → aeru

直す → 直せる naosu → naoseru

立つ → 立てる tatsu → tateru

Group 2: final "ru" becomes "[ra]reru"

食べる → 食べられる taberu → tabe[ra]reru

Group 3

来る → 来らみる kuru → ko[ra]reru

する → できる suru → dekiru

____________________

Note: The potential form is conjugated like a group 2 verb, therefore:

飲める → 飲めます, 飲めました nomeru → nomemasu, nomemashita

____________________

Note: Group 2 verbs and verb 来る kuru have the same ending られる -rareru in both the passive form and the potential form.
