kirsch-wasser n.

pulpy drupe of a well-known type of tree, c. 1300, earlier in surname Chyrimuth (1266, literally "Cherry-mouth"); from Anglo-French cherise, from Old North French cherise (Old French, Modern French cerise, 12c.), from Vulgar Latin *ceresia, from late Greek kerasian "cherry," from Greek kerasos "cherry tree," possibly from a language of Asia Minor. Beekes writes, "As the improved cherry came from the Pontos area ..., the name is probably Anatolian as well."

Mistaken in Middle English for a plural and stripped of its -s (compare pea). Old English had ciris "cherry" from a West Germanic borrowing of the Vulgar Latin word (cognate with German Kirsch), but it died out after the Norman invasion and was replaced by the French word.

Short for cherry-tree from 1620s. As an adjective, "of the color of a cherry," mid-15c.

The meaning "maidenhead, virginity" is by 1928, U.S. slang, from supposed resemblance to the hymen, but perhaps also from the long-time use of cherries as a symbol of the fleeting quality of life's pleasures (and compare English underworld slang cherry "young girl," attested from 1889). Cherry-bounce, popular name of a cordial made from fermented cherries, is from 1690s.

Old English wæter, from Proto-Germanic *watr- (source also of Old Saxon watar, Old Frisian wetir, Dutch water, Old High German wazzar, German Wasser, Old Norse vatn, Gothic wato "water"), from PIE *wod-or, suffixed form of root *wed- (1) "water; wet."

To keep (one's) head above water in the figurative sense is recorded from 1742. Water cooler is recorded from 1846; water polo from 1884; water torture from 1928. Linguists believe PIE had two root words for water: *ap- and *wed-. The first (preserved in Sanskrit apah as well as Punjab and julep) was "animate," referring to water as a living force; the latter referred to it as an inanimate substance. The same probably was true of fire (n.).

Proto-Indo-European root meaning "water; wet."
