noun
words of parting; farewells
A formal, literary term for parting words or farewell expressions. Rare in everyday speech; more common in classical or poetic contexts.

He left after a brief farewell.
卒業式で心のこもった訣辞を述べた。

From the kanji 訣 (parting, separation) and 辞 (word, speech). The exact historical derivation is uncertain; it is a Sino-Japanese compound (kango) likely coined in literary or classical Chinese-influenced writing.
