köken: From Dutch lakmoes, from Middle Dutch lecmoes, a compound of the cognates of German lecken (“to leak”) and Mus (“mush”). The former was later adapted to Dutch lak, German Lack (“varnish”). It seems obvious that there is a relation between Middle Dutch lecmoes and synonymous Old Norse litmosi (whence English litmus), but the nature of this relation is unsettled.
köken: From Middle Dutch lecmoes (1252), Middle Dutch lijcmoes (1459), early modern Dutch leeckmoes (1514), modern Dutch lackmoes (ca. 1620 and 1679). Equivalent to lekken + moes, the first element was later adapted by folk etymology to lak. Likely related to Old Norse litmosi, but the details of how they are related remain unclear.
