dish: [OE] Like dais, desk, and disc, dish comes ultimately from Greek dískos ‘quoit’. As their diversity of form and meaning suggests, they were acquired at various times and by various routes. English got dish around 700 AD from Latin discus, in which the original meaning ‘quoit’ had been extended metaphorically to ‘tray, platter, dish’ on the basis of the semantic features ‘roundness’ and ‘flatness’. => dais, desk, disc
Old English disc "plate, bowl, platter," from Latin discus "dish, platter, quoit," from Greek diskos "disk, platter" (see disk (n.)). A common West Germanic borrowing; Old High German borrowed the word as tisc "plate," but German tisch now means "table," in common with other later Romanic forms (such as Italian desco, French dais). Meaning "particular variety of food served" is first recorded mid-15c. Meaning "what one likes" is c. 1900; that of "attractive woman" is 1920s. Meaning "concave reflector or antenna" attested from 1948.
"to serve food," late 14c., from dish (n.). Meaning "to disparage, denigrate" first recorded 1940s; probably from the same notion in figurative dish it out "administer punishment" (1934). Related: Dished; dishing.
