köken: Inherited from Old East Slavic лучь (lučĭ), from Proto-Slavic *lučь (“ray; torch”), from Proto-Indo-European *lowkis, which is derived from *lewk-.
köken: Diffused from Mashreqi military colloquials, presumably a borrowing from Ottoman Turkish لغم (lağım). We cannot wholly rule out, perhaps via back-formation from a plural, kinship with لَاقُومَة (lāqūme, “putty”), as both matters are fitted to the joints of a building, in which case the Ottoman Turkish term can also be borrowed from Arabic.
köken: From Middle Korean *가ᄫᆞᆯ (*kaWol), from Old Korean *kapol (*kapol) or perhaps *kapul (*kapul). First attested in Hangul form only in the seventeenth century, but regularly indirectly attested since the eighth century in Chinese-language texts produced in Korea in the phonogramic form 加火魚 /加火鱼 (jiāhuǒyú).
shaft (in a mine; in a building) · mine (an explosive device)
çekim: çoğul aknák
köken: It is attested as Acnahege (*aknahegy) (1197/1337), Akana (1222), akonájá (1621). Ultimately from a Slavic language, from Proto-Slavic *okъno (“window”). The sense ‘explosive device’ came into being by ellipsis of tűzakna (“underground tunnel filled with explosives”, literally “fire shaft”).
Learned borrowing from Ancient Greek νάρκη (nárkē, “torpor, numbness; electric ray”). The "mine, landmine" sense is a loose semantic loan from French torpille (“electric ray; torpedo”), whence also τορπίλη (torpíli, “torpedo”).
