Selected source glosses provide context, not a complete modern definition inventory

From earlier cubbe. Origin unknown. According to Pokorny, from Proto-Germanic *kubb-, from Proto-Indo-European *gup- (“round object, knoll”), from *gew- (“to bend, curve, convex, arch, vault”). Related terms include cup (cf. cupboard), coffin, cove, etc, essentially “chamber”, thus cub maybe initially derived from the sense “den”, or maybe “womb”. A probable cognate is also found in North Germanic: dialectal Swedish kubbe, kybbe, köbbe, kibb, Danish kippe (“calf”). Also compare Icelandic and Old Norse kobbi (“seal”), Old Irish cuib (“whelp”). Compare also English cob. Originally, the meaning was specifically "young fox", in which sense it has largely replaced English whelp.

Where this record stops

This page does not supply an independently verified sound-change sequence, first-use manuscript or complete family tree unless a cited analysis explicitly establishes one. Missing detail here is a limit of this record—not a claim that humanity knows nothing more.

An older meaning does not determine what a word must mean today. Follow the sources, preserve disagreements, and keep ancestry separate from interpretation.
