How To Conjugate The Japanese Verb: 'To Do'

Like the verb 'to come' (kuru 来る), the verb suru "する" (to do) is also an important irregular verb in Japanese.

This is one of the easiest verbs to conjugate.

There are several different verbs which are formed as a combination between a noun and the verb suru. As an example, we can mention the verb Kaiketsu suru (解決する) that means 'to resolve a problem'.

In addition, Suru as a verb has other interesting combinations, formed with the ending 'jiru'.

For example the verb ronjiru (論じる) that means 'to debate'.
