Ichidan Verbs

Ichidan Verbs - 一段動詞

The second group of verbs are called Ichidan (一段) verbs. It is usually an Ichidan verb if it ends with the sound "iru" or "eru". Ichidan verbs also follow a simple conjugation pattern that is somewhat similar to that of the Godan verbs. Here's an example:

漢字 - Kanji ひらがな - Hiragana Romaji (English Letters) Verb Base 食べる たべる taberu (to eat) 食べ たべ tabe Base 1 食べ たべ tabe Base 2 食べる たべる taberu Base 3 食べれ たべれ tabere Base 4 食べよう たべよう tabeyou Base 5 食べて たべて tabete Base "te" 食べた たべた tabeta Base "ta"

Base 1 and Base 2: As you can see, Base 1 and 2 are the same. Just like with the Godan verbs, a negative can be made by adding -nai (ex. tabenai - I will not eat.) and this base, or root form, is also used for the formal form of the verb.

Base 3: Base 3 is the same as with Godan verbs.

Base 4: Base 4, however, can not be used by itself like with Godan verbs. It is only used for "if verb" by adding -ba. (ex. tabereba - If I eat it...) It is not the low command form for Ichidan verbs. The low command form for Ichidan verbs is Base 1 + ろ (ro).

Base 5: Base 5 is the same as with Godan verbs.

Base "te" and Base "ta": The Base "te" and "ta" forms for Ichidan verbs are a lot easier than with Godan verbs. Simply take off the "ru" and add a "te" for Base "te" and a "ta" for Base "ta". These have the same functions as with Godan verbs.

Here are some Ichidan verbs. Try conjugating them on a piece of paper using what you have just learned. Click here for the answers.

Irregular Verbs

The last type of verbs are the Irregular verbs but there are only 2 of them in the entire language so just memorize their charts below. The first one is suru (to do something). Many nouns can be used as a verb simply by putting "suru" right after them. It is probably the most used of all Japanese verbs. The second Irregular verb is kuru (to come).

漢字 - Kanji ひらがな - Hiragana Romaji (English Letters) Verb Base する する suru (to do) し し shi Base 1 し し shi Base 2 する する suru Base 3 すれ すれ sure Base 4 しよう しよう shiyou Base 5 して して shite Base "te" した した shita Base "ta"

The functions for these bases are the same as for the Godan verbs except that Base 4 can only be used as the "if verb".
The rude command form is "Shiro".

漢字 - Kanji ひらがな - Hiragana Romaji (English Letters) Verb Base 来る くる kuru (to come) 来 こ ko Base 1 来 き ki Base 2 来る くる kuru Base 3 来れ くれ kure Base 4 来よう こよう koyou Base 5 来て きて kite Base "te" 来た きた kita Base "ta"

The functions for these bases are the same as for the Godan verbs except that Base 4 can only be used as the "if verb".
The rude command form is "Koi" and really should only be used on animals.
