Why turkey has the same name as Turkey
"a line or band in cloth," 1620s (but probably much older), from Middle Dutch or Middle Low German stripe "stripe, streak," from Proto-Germanic *stripanan (cf. Danish stribe "a striped fabric," German Streifen "stripe"), cognate with Old Irish sriab "stripe," from PIE root *streig- (see strigil). Of soldiers' chevrons, badges, etc., attested from 1827.
"a stroke or lash," mid-15c., probably a special use of stripe (n.1), from the marks left by a lash. Cf. also Dutch strippen "to whip," West Frisian strips, apparently cognate but not attested as early as the English word.
