stroke

stroke: The verb stroke [OE] and the noun stroke [13] are different words, but they come ultimately from the same source – the prehistoric Germanic base *strīk-, *straik- ‘touch lightly’ (from which English also gets streak and strike). The verb has stayed very close semantically to its source, whereas the noun has followed the same path as its corresponding verb strike.
=> streak, strike

stroke (n.)

"act of striking," c. 1300, probably from Old English *strac "stroke," from Proto-Germanic *straik- (cognates: Middle Low German strek, German streich, Gothic striks "stroke"); see stroke (v.).

The meaning "mark of a pen" is from 1560s; that of "a striking of a clock" is from mid-15c. Sense of "feat, achievement" (as in stroke of luck, 1853) first found 1670s; the meaning "single pull of an oar or single movement of machinery" is from 1731. Meaning "apoplectic seizure" is from 1590s (originally the Stroke of God's Hand). Swimming sense is from 1800.

stroke (v.)

"pass the hand gently over," Old English stracian "to stroke," related to strican "pass over lightly," from Proto-Germanic *straik-, from PIE root *streig- "to stroke, rub, press" (see strigil). Figurative sense of "soothe, flatter" is recorded from 1510s. The noun meaning "a stroking movement of the hand" is recorded from 1630s. Related: Stroked; stroking.
