Japanese[edit]

Etymology 1[edit]

From Classical Japanese さす (sasu), which followed 下二段活用 (shimo nidan katsuyō, lower bigrade conjugation).

Some linguists suggest that させる is a variant of せる, where a reduplicative "s" is added to avoid vowel clusters. (e.g. 食べる + せる → *tabe- + *-ase- → *tabease- + *tabesase- → 食べさせる)

Suffix[edit]

させる (ichidan conjugation, rōmaji -saseru)

  1. (jodōshi) Used to form the causative of verbs.
    1. Expresses causation: to make ... do ...
Conjugation[edit]
Usage notes[edit]

Attaches only to the 未然形 (mizenkei, irrealis or incomplete form) of Group II (ichidan) verbs and the irregular verb  () (kuru). The result is conjugated like a Group II (ichidan) verb.

The passive form of verbs from other conjugation classes are formed with せる (-seru) instead of させる (-saseru).

In colloquial speech, させる (-saseru) can be contracted to さす (-sasu), which follows 五段活用 (godan katsuyō, quinquigrade conjugation).
