- rakish (adj.)
[rakish 词源字典] - 1706, "debauched, disreputable," from rake (n.2) + -ish. Related: Rakishly; rakishness.
The meaning "smart, jaunty, dashing" (1824) is said to be a different word, probably from rake "slant, slope" (1620s), used especially in reference to any deviation from the vertical in a ship's masts, of uncertain origin, perhaps from Scandinavian (compare Old Swedish raka "project, reach;" Danish rage "protrude, project") related to Old English reccan "stretch." "The piratical craft of former times were distinguished for their rakish build" [Century Dictionary].[rakish etymology, rakish origin, 英语词源]
