smart

smart: [OE] Smart originated as a verb, meaning ‘be painful’. It came from a West Germanic base *smert-, *smart- (source also of German schmerz and Dutch smart ‘pain’), which may go back ultimately to the same Indo-European ancestor that produced Greek smerdnós ‘terrible’ and Latin mordēre ‘bite’ (source of English morsel, remorse, etc). The adjective smart was derived from the verb in the 11th century, and at first meant ‘stinging, painful’. Its modern senses ‘clever’ and ‘neat’ emerged in the 17th and 18th centuries respectively.
=> morsel, remorse

smart (v.)

Old English smeortan "be painful," from Proto-Germanic *smarta- (cognates: Middle Dutch smerten, Dutch smarten, Old High German smerzan, German schmerzen "to pain," originally "to bite"), from PIE *smerd- "pain," an extension of the root *mer- (2) "to rub; to harm" (cognates: Greek smerdnos "terrible, dreadful," Sanskrit mardayati "grinds, rubs, crushes," Latin mordere "to bite"). Related: Smarted; smarting.

smart (adj.)

late Old English smeart "painful, severe, stinging; causing a sharp pain," related to smeortan (see smart (v.)). Meaning "executed with force and vigor" is from c. 1300. Meaning "quick, active, clever" is attested from c. 1300, from the notion of "cutting" wit, words, etc., or else "keen in bargaining." Meaning "trim in attire" first attested 1718, "ascending from the kitchen to the drawing-room c. 1880" [Weekley]. For sense evolution, compare sharp (adj.).
