deject (v.)

early 15c., dejecten, "to throw or cast down," a sense now obsolete, from Latin deiectus "a throwing down, felling, fall," past participle of deicere "to cast down, destroy; drive out; kill, slay, defeat," from de- "down" (see de-) + -icere, combining form of iacere "to throw" (from PIE root *ye- "to throw, impel"). The figurative sense of "depress in spirit, discourage, dispirit" is from c. 1500.
