Word History

Etymology

Verb (1)

Middle English lacchen "to catch, seize, take, obtain (transitive or with on, up)," going back to Old English læccan "to take hold of, snatch, seize" (class I weak verb), perhaps going back to Indo-European *sleh₂g^w- "take, seize," whence also Greek lázomai, lázesthai "to take hold of," lambánō, lambánein "to grasp, take hold of"

Note: The Old English verb is without evident Germanic congeners. If cognate with the Greek verb, whose dialect forms show traces of an initial s, the outcome *lak-i̯e- in Germanic rather than *(s)lok-i̯e- or *(s)ulk-i̯e- (with loss of mobile s) must somehow be analogical.

Noun

Middle English lacche, probably derivative of lacchen "to catch, seize" — more at latch entry 1
