dejection (n.)

early 15c., dejeccioun, "unhappy condition, degradation, humiliation;" c. 1500, "state of being depressed or in low spirits," from Old French dejection "abjection, depravity; a casting down" and directly from Latin deiectionem (nominative deiectio), noun of action from past-participle stem of deicere "to cast down," from de- "down" (see de-) + -icere, combining form of iacere "to throw" (from PIE root *ye- "to throw, impel"). The literal sense "act of casting down" (1680s) is rare in English.
