köken: Uncertain. Most Romanists conclude that the word ultimately comes from Latin coactāre, but they are uncertain how exactly it evolved due to phonological problems and the early attestation in Portuguese and Galician. It could possibly be: * From Spanish agachar; * From an unattested Vulgar Latin *coactiāre through a Mozarabic word. Cognate with Galician and Spanish agachar and Catalan acotar.
köken: From Proto-Vietic *guːrʔ ~ *kuːrʔ; cognates with Muong củi, Chut cûl, Chut [Maleng] kuːl⁴ and Tho [Pong] kuːl⁴. Also compare Angkorian Old Khmer កុរ៑ (kur), a loan from an unidentified Vietic source, whence Khmer កុរ (kol, “Year of the Pig”) and Thai กุน (gun, “Year of the Pig”). (Ferlus, 2013) Additionally, 亥 (OC *[ɡ]ˤəʔ) (B-S) (SV: hợi) is a possible cognate, see there for more.
