#### Usage notes

This is the ancient form, also used somewhat in Classical Japanese. The modern equivalents are 出る (deru, intransitive) and 出す (dasu, transitive).
Although the conjugation pattern is consistently described in references as 下二段活用 (shimo nidan katsuyō, “lower bigrade conjugation”), the existence of causative / transitive form 出だす (idasu) and compound forms such as 泉 (izumi, “spring, water source”, literally “come out + water”) and 出石 (Izushi, a place in Hyogo Prefecture, literally “come out + stone”) suggest an earlier 四段活用 (yodan katsuyō, “quadrigrade conjugation”) pattern.
