於戲

Interjection

 * 1)  ah; o; la; lo; alas; alack; well onomatopoeic of sighing and signifying relief, closure, emphasis, admiration, calling to attention, or sadness, etc.

Usage notes
Chiefly used at sentence-initial. Although is considered equivalent to  as an onomatopoeic interjection, it cannot be substituted where the latter is used as a verb that means "to die" (euphemistically or jocularly). For example, is considered idiomatic, but *一命於戲 is awkward or incorrect.
