Verb Conjugations

Ichidan

Ichidan Verbs are easy, the ending る is replaced with the Ichidan Helper Verb in the Godan tables below for each form.

Godan

Godan verbs make use of the Conjugation Colum to identify the last sound change required to transform into each form. For simplicity every conjugation will use はなす as the example.

た and て Form

The table below shows the conjugations for all Godan verbs into both the た and て forms. The Verb Ending is replaced to make the て and た Forms.

Verb Ending	て Form	た Form
`う`, `つ`, `る`	`って`	`った`
`ぬ`, `ぶ`, `む`	`んで`	`んだ`
`す`	`して`	`した`
`く`	`いて`	`いた`
`ぐ`	`いで`	`いだ`

NOTE: Ichidan Helper Verb is excluded form this table is its literally as simple as replacing the ending る with て or た.

Conjugation Columns (Other Forms)

All Godan verbs are in the centre う row in their dictionary form. Conjugating requires moving across the kana chart (Left <–> right in the one below).

The last う sound of the Verb is replaced with the sound in the corresponding colum of each conjugation type.

    <------>
あ　い　う　え　お
か　き　く　け　こ
さ　し　す　せ　そ
た　ち　つ　て　と
な　に　ぬ　ね　の
ば　び　ぶ　べ　ぼ
ま　み　む　め　も
ら　り　る　れ　ろ
    <------>

NOTE: There is 1 single exception to this rule. う moving to the あ colum has the sound change to わ rather than あ.
