Japanese/Ichidan verb conjugations

Ichidan Verbs are most verbs that end with the letters -iru and -eru only (some verbs that end with them are actually godan verbs). This includes the verb "Iru" (to be in a place) itself. We will use the verb Taberu (to eat) to illustrate the different forms of conjugation for an Ichidan verb. Ichidan is so named due to the fact that it has only one phase. Not many letters are changed, the ending is simply dropped and a suffix is tacked on.

Negative:

Drop the "-ru" ending and add "-nai." Thus Taberu becomes Tabenai: "not eat."

Infinitive:

Drop the "-ru" ending and add "-masu." Taberu becomes Tabemasu: "eat". This verb form may be modified just like in Godan form to Tabemasen and Tabemashou.

Dictionary:

Keep the verb the same.

Imperative/Conditional:

Drop the "-ru" and add "-ro." Taberu becomes Tabero "eat!!" For conditional, change "-ru" to "-reba." Taberu becomes Tabereba - "what if you ate?"

Volitional:

Drop the "-ru" and add "-you". Taberu becomes Tabeyou: "let's eat." It's very easy once you have seen the godan conjugation form.
