Is the Latin term Trix for a female person related to the term turning tricks as related to prostitution? I have reviewed the origination of turning tricks as noted on this site. However, it did not mention anything about the Latin origin of Trix itself. It only mentions the French term trique.
The noun trick and the suffix -trix are not related in English. If they share a common origin, it would predate their Latin origin:
early 15c., "a cheat, a mean ruse,"
from Old North French trique "trick, deceit, treachery, cheating,"
from trikier "to deceive, to cheat," variant of Old French trichier "to cheat, trick, deceive," of uncertain origin,
probably from Vulgar Latin *triccare,
from Latin tricari "be evasive, shuffle,"
from tricæ "trifles, nonsense, a tangle of difficulties," of unknown origin.
Meaning "a roguish prank" is recorded from 1580s; sense of "the art of doing something" is first attested 1610s.
Meaning "prostitute's client" is first attested 1915; earlier it was U.S. slang for "a robbery" (1865).
To do the trick "accomplish one's purpose" is from 1812;
to miss a trick "fail to take advantage of opportunity" is from 1889; from 1872 in reference to playing the card-game of whist, which might be the original literal sense.
Trick-or-treat is recorded from 1942. Trick question is from 1907.
