Luck
late Middle English (as a verb): perhaps from Middle Low German or Middle Dutch lucken . The noun use (late 15th century) is from Middle Low German lucke, related to Dutch geluk, German Glück, of West Germanic origin and possibly related to lock1.
wiktionary
From Middle English luk, lukke, related to Old Frisian luk(“luck”), West Frisian gelok(“luck”), Saterland Frisian Gluk(“luck”), Dutch geluk(“luck, happiness”), Low German luk(“luck”), German Glück(“luck, good fortune, happiness”), Danish lykke(“luck”), Swedish lycka(“luck”), Icelandic lukka(“luck”). According to the OED, it may be related to lock.
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 lücke, gelücke (modern German Glück). The word occurs only from the 12th century, apparently first in Rhine Frankish. Perhaps from a 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 fortūne from Latin fortūna. 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.
etymonline
luck (n.)
c. 1500, "fortune good or bad, what happens to one by chance (conceived as being favorable or not); good luck, quality of having a tendency to receive desired or beneficial outcomes," not found in Old English, probably from early Middle Dutch luc, shortening of gheluc "happiness, good fortune," a word of unknown origin. It has cognates in Modern Dutch geluk, Middle High German g(e)lücke, German Glück "fortune, good luck."
Perhaps first borrowed in English as a gambling term. To be down on (one's) luck is from 1832; to be in luck is from 1857; to push (one's) luck is from 1911. Good luck as a salutation to one setting off to do something is from 1805. Expression no such luck, expressing disappointment that something did not or will not happen, is by 1835. Better luck next time as an expression of encouragement in the face of disappointment is from 1858, but the expression itself is older:
A gentleman was lately walking through St Giles's, where a levelling citizen attempting to pick his pocket of a handkerchief, which the gentleman caught in time, and secured, observing to the fellow, that he had missed his aim, the latter, with perfect sang-froid, answered, "better luck next time master." [Monthly Mirror, London, September 1802]
Luck of the draw (1892) is from card-playing. In expressions often ironical, as in just (my) luck (1909). To be out of luck is from 1789; to have one's luck run out is from 1966.
luck (v.)
"to have (good) luck," by 1945, from luck (n.). To luck out "succeed through luck" is American English colloquial, attested by 1946; to luck into (something good) is from 1944. Lukken (mid-15c.) was a verb in Middle English meaning "to happen, chance;" also "happen fortunately" (from the noun or from Middle Dutch lucken), but the modern word probably is a new formation.
