Origin and meaning of discreet

late-14c., "morally discerning, prudent, circumspect, wise or judicious in avoiding mistakes," from Old French discret "discreet, sensible, intelligent, wise," from Latin discretus "separated, distinct," in Medieval Latin "discerning, careful," past participle of discernere "to separate, set apart, divide, distribute; distinguish, perceive," from dis- "off, away" (see dis-) + cernere "distinguish, separate, sift" (from PIE root *krei- "to sieve," thus "discriminate, distinguish").

Meaning "separate, distinct" in English is late 14c. Spellings discrete and nativized discreet co-existed until after c. 1600, when discreet became the common word for "careful, prudent," and discrete was maintained in philosophy, medicine, music and other disciplines that remembered Latin and took some pains to show it. Related: Discreetly.

sapient (adj.)

"wise, sage, discerning," late 15c. (early 15c. as a surname), from Old French sapient and directly from Latin sapientem (nominative sapiens) "sensible; shrewd, knowing, discrete;" also "well-acquainted with the true value of things" (like Greek sophos), a specialized use of the present participle of sapere, of things, "to taste, have taste;" of persons, "to have discernment, be wise."

This is reconstructed to be from PIE root *sep- (1) "to taste, perceive;" source also of Old Saxon ansebban "to perceive, remark," Old High German antseffen, Old English sefa "mind, understanding, insight," Old Norse sefi "thought"). "[N]ow generally used ironically" [Century Dictionary]. Related: Sapiently; sapiential.

galaxy (n.)

late 14c., from French galaxie or directly from Late Latin galaxias "the Milky Way" as a feature in the night sky (in classical Latin via lactea or circulus lacteus), from Greek galaxias (adj.), in galaxias kyklos, literally "milky circle," from gala (genitive galaktos) "milk" (from PIE root *g(a)lag- "milk").

The technical astronomical sense in reference to the discrete stellar aggregate including the sun and all visible stars emerged by 1848. Figurative sense of "brilliant assembly of persons" is from 1580s. Milky Way is a translation of Latin via lactea.

See yonder, lo, the Galaxyë Which men clepeth the Milky Wey, For hit is whyt. [Chaucer, "House of Fame"]

Originally ours was the only one known. Astronomers began to speculate by mid-19c. that some of the spiral nebulae they could see in telescopes were actually immense and immensely distant structures the size and shape of the Milky Way. But the matter was not settled in the affirmative until the 1920s.
