From Middle English luk, lukke, related to Old Frisian luk (“luck”), West Frisian gelok (“luck”), Dutch geluk (“luck, happiness”), Low German luk (“luck”), German Glück (“luck, good fortune, happiness”), Danish lykke (“luck”), Swedish lycka (“luck”), Icelandic lukka (“luck”).
Loaned into English in the 15th century (probably as a gambling term) from Middle Dutch luc, a shortened form of: gheluc (“good fortune”) (whence Modern Dutch geluk). Middle Dutch luc, gheluc is paralleled by Middle High German lück, gelücke (modern German Glück). The word occurs only from the 12th century, apparently first in Rhine Frankish. Perhaps from an Old Frankish *galukki. The word enters standard Middle High German during the 13th century, and spreads to English and Scandinavian in the Late Middle Ages. Its origin seems to have been regional or dialectal, and there were competing German words such as gevelle or schick, or the Latinate fortune. Its etymology is unknown, although there are numerous proposals as to its derivations from a number of roots.
Use as a verb in American English is late (1940s), but there was a Middle English verb lukken "to chance, to happen by good fortune" in the 15th century.
