Difference between Ichidan and Yo^dan Japanese verbs baby steps toward mastery

In order to put verbs into bases, it’s necessary to understand the difference between Ichidan verbs and Yo^dan verbs. I was taught that there exists three types of verbs but these types are unrelated to the three types of English verbs. In English, the three types of verbs are passive, active and forms of the copula- to be.

With the exception of irregular verbs,
Ichidan verbs are any Japanese verb that end in eru or iru.

Examples of ichidan verbs

Iru
Eru
Obieru
Oshieru


Yo^dan verbs are any that do not end in eru or iru.

Examples of yo^dan verbs

Yaru
Utsu
Komu
Oyogu


The ^ carat symbol = the long vowel, or, double vowel sound, sometimes indicated with a ‘u’.
