Hello and welcome back to our Japanese verb conjugation series were we conjugate Japanese verbs, who would have thought it! So to recap in the last online Japanese lesson we looked at conjugating Japanese masu form verbs into different tenses.

Well my friends im sorry to tell you, that was a walk in the park compared to what’s to come. However do not despair, we are here to help you get through it!

Today we are going to look at conjugating Japanese plain form verbs. These are the verbs that end in U sounds and are a little more informal compared to “Masu” form verbs. Now we already covered the different verb groups in Japanese but let’s re-cap as you are going to need this vital information.

Plain form : Japanese Verb Groups

Group 1:

IRU/ERU Verbs – Verbs that end in IRU いるand ERUえる- such as: みる Miru たべる Taberu

Group 2:

Verbs in group 2 end with syllables ku (く), gu (ぐ), su (す), mu (む), nu (ぬ), bu (ぶ), u (う), tsu (つ), or ru (る).

Group 3:

Is made up of only two verbs, Suruする and Kuru くる.

Depending on what group the verb is in the verb conjugation will be different. Some groups are easier than others as I’m sure you will soon find out. In today’s Japanese lesson we are going to be looking at how to conjugate plain form verbs into the past.

It is a big task, and possibly the hardest when it comes to Japanese verb conjugation, however once you master this the world is your oyster.

So firstly we will start with the easiest group, group 1 – Iru + Eru verbs. To conjugate this group to past tense all you do is take off the “ru” る and add “ta” た. This is one of the simplest groups to work with for verb conjugation.
