köken: Unadapted borrowing from English bacon, from Middle English bacon (“meat from the back and sides of a pig”), from Old French bacon, bacun (“ham, strip of lard”), from Frankish *bakkō, from Proto-Germanic *bakō, *baką, *bakaz (“back”), from Proto-Indo-European *bʰeg- (“back, buttocks; to vault, arch”). Attested since 1899.
side (of a human or an animal) · side, belly (cut of pork meat) · loin (cut of beef)
çekim: çoğul kyljet · tamlayan kyljen
köken: From Proto-Finnic *külki (compare Estonian külg, Veps külʹg). Initially likely an anatomical term, although it has also developed the more abstract meaning “side” in most other Finnic languages as well.
From the same word family as lašė́ti (“to drip, flow in drops”), i.e. "meat that drips (with oil)", though the exact morphological details are unclear. Either analyzed as laš-iniai, in which case directly from lašė́ti, or analyzed as lašin-iai, in which case from the related lãšinti (“to drip, pour in drops”).
