köken: Inherited from Proto-Slavic *žukъ. Per Vasmer (and others) likely related to жужжа́ть (žužžátʹ), жу́желица (žúželica). Per Chernykh, however, likely related to Proto-Slavic *govędo (denied by Anikin).
köken: From *bȫgček, where -ček is a diminutive suffix, from Proto-Turkic *bȫg (“insect”). Cognate with Tatar бөҗәк (böcäk, “insect”), Kazakh бөжек (böjek, “insect”), Azerbaijani böcək, Turkmen möjek, Crimean Tatar böcek, Turkish böcek (“insect”), etc.
köken: Cognate with Old Norse and Icelandic baggi, Old Norse bǫggr, Middle English bagge. The hypothesis for the shift in sense from "bag" to "ram" is by reference to the testicles of an unneutered ram. Doublet of bagage and packe.
From Proto-Southwestern Tai *mlɛːŋᴬ (“insect”) which /-l-/ is dropped, from Proto-Tai *m.leːŋᴬ (“insect”), which is either from Middle Chinese 螟蛉 (MC meng leng, “caterpillar”) or native Tai borrowed into Chinese. Doublet of แมลง (má-lɛɛng). Cognate with Lao ແມງ (mǣng), Tai Dam ꪵꪣꪉ, Tai Nüa ᥛᥦᥒᥰ (mäeng), Zhuang nengz.
