egest (v.)[egest 词源字典]: "to discharge, pass off, expel," especially "defecate," c. 1600, from Latin egestus, past participle of egerere "to bring out, discharge, vomit," from assimilated form of ex- "out" (see ex-) + gerere "to carry, bear" (see gest). The opposite of ingest. Related: Egested; egesting; egesta.[egest etymology, egest origin, 英语词源]
lemon (n.2): "worthless thing," 1909, American English slang; from lemon (n.1), perhaps via criminal slang sense of "a person who is a loser, a simpleton," which is perhaps from the notion of someone a sharper can "suck the juice out of." A pool hall hustle was called a lemon game (1908); while to hand someone a lemon was British slang (1906) for "to pass off a sub-standard article as a good one." Or it simply may be a metaphor for something which leaves a bad taste in one's mouth.
transpire (v.): 1590s, "pass off in the form of a vapor or liquid," from Middle French transpirer (16c.), from Latin trans- "through" (see trans-) + spirare "to breathe" (see spirit (n.)). Figurative sense of "leak out, become known" is recorded from 1741, and the erroneous meaning "take place, happen" is almost as old, being first recorded 1755. Related: Transpired; transpiring.
