From Middle English cogge, from Old Norse (compare Norwegian kugg ‎(“cog”), Swedish kugg, kugge ‎(“cog, tooth”)), from Proto-Germanic *kuggō (compare Dutch kogge ‎(“cogboat”), German Kock ‎(“id.”)), from Proto-Indo-European *gugā ‎(“hump, ball”) (compare Lithuanian gugà ‎(“pommel, hump, hill”)), from *gēu- ‎(“to bend, arch”).
