Is this the correct way to identify Group 1 verbs?


From what I have been able to find I came up with this:

Verbs ending in:

える ける せる てる ねる へる める れる げる ぜる でる べる ぺる

いる きる しる ちる にる ひる みる りる ぎる じる ぢる びる ぴる

but not these verbs:

かえる はしる きる いる はいる

I spent time looking at different web pages on verbs but from what I see none
of them seem to give a really good way to identify Group 1 and also show all
the exceptions. Can someone confirm if the checks I am making are correct or
let me know if they are aware of more exceptions that I should take into
account?

Thanks




Yes, group 1 verbs always end in ~iru and ~eru. As you said, いる (要る）as in
'need' is not group 1, nor are the other words in your list. However, いる (居る)
as in 'exist' is group 2.

The other exceptions can be found on this page:
<http://www.jgram.org/pages/viewOne.php?tagE=Group+1+Verb+Exceptions>. There
is quite a lot of them. But the examples you gave in your post are the more
commonly used ones.

To repeat what the author says on that web page: There is a rule of thumb for
judging whether a ~e/iru verb is group one or not. If there is more than one
syllable before the ~ru, you look for the expression of the word with its
kanji, e.g. 嘲る [あざける]. If the ~e/~i syllable is written in kana, it is group
2. Otherwise, it is group 1.

The author notes あぶらぎる and まじる are two exceptions to this rule. Also, if the
word is only written in kana, you can't use the rule to determine which group
it belongs to - e.g. bibi-ru and nome-ru. One syllable roots are also
problematic when using this rule - e.g. he-ru (Group 1) and mi-ru (Group 2).
ふせる could be either group, depending on how it's used.

Doesn't seem like there is a simpler rule. You just learn the exceptions from
reading, speaking, listening and writing. People will (hopefully) correct your
mistakes, so you can learn better.
