Causative Form (Verb Conjugation)

Causative Form (Verb Conjugation)

The Causative Form is the opposite of the Passive Form, however the conjugation for both forms is very similar (in which the Causative Form follows the exact same steps to conjugation as the Passive Form but replaces every instance of れる with せる and every instance of られる with させる).

To conjugate る-Verbs into their Causative Form, drop the final る character and replace it with させる.

Example(s):

見る (みる) = 見させる (みさせる)
食べる (たべる) = 食べさせる (たべさせる)
寝る (ねる) = 寝させる (ねさせる)

To conjugate う-Verbs that end in the vowel character う into their Causative Form, drop the final う and replace it with わせる.

Example(s):

買う (かう) = 買わせる (かわせる)
言う (いう) = 言わせる (いわせる)

To conjugate う-Verbs that end in any character other than the vowel character う into their Causative Form, drop the “u” inside the final character to isolate the respective consonant that should now be at the end of the verb and replace it with an “a” to form a new Japanese character. Then, add after it all せる.

Example(s):

死ぬ (しぬ) = 死なせる (しなせる)
行く (いく) = 行かせる (いかせる)
読む (よむ) = 読ませる (よませる)

There are two irregular verbs for the Causative Form and they are the same two for the Passive Form:

来る = 来させる
する = させる
