diatribe: [16] Diatribe’s connotations of acrimoniousness and abusiveness are a relatively recent (19th-century) development. Originally in English it meant simply ‘learned discourse or disquisition’. It comes via Latin diatriba from Greek diatribé ‘that which passes, or literally wears away, the time’, and hence, in scholarly circles, ‘study’ or ‘discourse’. This was a derivative of diatribein ‘pass, waste, while away’, a compound verb formed from the intensive prefix dia- and tríbein ‘rub’. => attrition, detriment, trite
diatribe (n.)
1640s (in Latin form in English from 1580s), "discourse, critical dissertation," from French diatribe (15c.), from Latin diatriba "learned discussion," from Greek diatribe "employment, study," in Plato, "discourse," literally "a wearing away (of time)," from dia- "away" (see dia-) + tribein "to wear, rub," from PIE root *tere- (1) "to rub, turn, twist" (see throw (v.)). Sense of "invective" is 1804, apparently from French.
