Japanese consanant verbs that end with eru/iru

Japanese has two verb types, consonant (godan) verbs and vowel (ichidan) verbs, each with their corresponding conjugations. Here is an example of each with conjugation into the past and -masu forms.

Vowel (ichidan)

• 食べる (taberu) – to eat
  • Past: 食べた (tabeta)
  • ~Masu (polite): 食べます (tabemasu)

Consonant verb (godan)

• 分かる (wakaru) – to understand
  • Past: 分かった (wakatta)
  • ~Masu (polite): 分かります (wakarimasu)

The vowel verbs typically end with eru/iru, however there are some verbs that end in eru/iru which are consonant verbs. These can be looked up in a dictionary, but I’ve listed some of the most common ones below.

• 走る (hashiru) – to run
• 帰る (kaeru) – to return (home)
• つねる (tsuneru) – to pinch
• 要る (iru) – to need
• 喋る (shaberu) – to speak, to chat
• 切る(kiru) – to cut
• 知る (shiru) – to know
• 蹴る (keru) – to kick
• 散る (chiru) – to scatter
• 焦る (aseru) – to hurry
• 握る (nigiru) – to grasp
• 弄る（ijiru) – to fiddle with
• 入る (hairu) – to enter

Supposedly there are roughly 100 of these in total, and if you want to see a bigger list check here.
