Japanese verbs do not change according to who does the action. However, they do change according to tense (when an action happens), whether one is saying an action happened or did not happen, and various other things (to be discussed below).
The plain form of a regular verb always ends in a vowel succeeded by one of the following: u, tsu, mu, bu, ku gu, su or ru. Each of these, except ru, corresponds to a different conjugation. Ru can be either of two conjugations. If the vowel before the ru is a, o or u, the verb must be an regular ru verb. If the vowel is i or e, it can be either an regular ru verb or irregular ru verb. Now we can start with the most useful verb forms: the i form and te form. This is conjugated as follows:
|Verb conjugation||Plain suffix||i form suffix||te form suffix|
|ru||(i or e)-ru||No suffix||-te|
