# Japanese Verb Conjugation (Ichidan + Irregular)

## Ichidan Verbs - ไธๆฎตๅ่ฉ

The second group of Japanese verbs are called Ichidan (ไธๆฎต) verbs.

It is usually an Ichidan verb if it ends with the sound "iru" or "eru". Some well used Japanese verbs which appear to be Ichidan but are really Godan are listed below. Ichidan verbs also follow a simple conjugation pattern that is somewhat similar to that of the Godan verbs.

Below is a verb conjugation chart for Japanese Ichidan verbs:

ๆผขๅญ - Kanji | ใฒใใใช - Hiragana | Romaji (English Letters) | English Meaning |
---|---|---|---|

้ฃในใ | ใในใ | taberu (to eat) | |

้ฃใน | ใใน | tabe | Base 1 |

้ฃใน | ใใน | tabe | Base 2 |

้ฃในใ | ใในใ | taberu | Base 3 |

้ฃในใ | ใในใ | tabere | Base 4 |

้ฃในใใ | ใในใใ | tabeyou | Base 5 |

้ฃในใฆ | ใในใฆ | tabete | Base "te" |

้ฃในใ | ใในใ | 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 + ใ (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.

See the tables below for conjugations.

## 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).
