Possibly a devoiced variant of gungë + -ull, from Proto-Indo-European*geng-, *gong- 'lump'. Close to Lithuanian gungulỹs(“ball”), Old Norse kǫngull(“bundle of berries”), Ancient Greek γογγύλος(gongúlos, “round”), Latin conucla(“staff for holding flax, wool, etc.”). Alternatively from Proto-Albanian *kunkula similar to Lithuanian kunkulas, "bubble".
