native people of Peru and surrounding regions, 1811, from Spanish, from Quechua (Inca) kechua "plunderer, destroyer." Also the name of their language. Related: Quechuan.

Old English cwen "queen, female ruler of a state, woman, wife," from Proto-Germanic *kwoeniz (source also of Old Saxon quan "wife," Old Norse kvaen, Gothic quens), ablaut variant of *kwenon (source of quean), from PIE root *gwen- "woman."

The original sense seems to have been "wife," specialized by Old English to "wife of a king." In Old Norse, still mostly of a wife generally, as in kvan-fang "marriage, taking of a wife," kvanlauss "unmarried, widowed," kvan-riki "the domineering of a wife."

English is one of the few Indo-European languages to have a word for "queen" that is not a feminine derivative of a word for "king." The others are Scandinavian: Old Norse drottning, Danish dronning, Swedish drottning "queen," in Old Norse also "mistress," but these also are held to be ultimately from male words, such as Old Norse drottinn "master."

Used of chess piece from mid-15c. (as a verb in chess, in reference to a pawn that has reached the last rank, from 1789), of playing card from 1570s. Of bees from c. 1600 (until late 17c., they generally were thought to be kings; as in "Henry V," I.ii, but the Anglo-Saxons knew better: their word was beomodor); queen bee in a figurative sense is from 1807. Meaning "male homosexual" (especially a feminine and ostentatious one) first certainly recorded 1924; probably here an alteration of quean, which is earlier in this sense. Queen Anne first used 1878 for "style characteristic of the time of Queen Anne of Great Britain and Ireland," who reigned 1702-14. Cincinnati, Ohio, has been the Queen City (of the West) since 1835.

"to spoil, ruin," 1812, from queer (adj.). Related: Queered; queering. Earlier it meant "to puzzle, ridicule, cheat" (1790). To queer the pitch (1846) is in reference to the patter of an itinerant tradesman or showman (see pitch (n.1)).

These wanderers, and those who are still seen occasionally in the back streets of the metropolis, are said to 'go a-pitching ;' the spot they select for their performance is their 'pitch,' and any interruption of their feats, such as an accident, or the interference of a policeman, is said to 'queer the pitch,'—in other words, to spoil it.
