Plural of cob; the woody central cores of corn ears, male swans, rounded lumps, or types of horses.
From Middle English 'cob' meaning lump or rounded thing, likely from Old Norse 'kobbalr.' The term expanded to cover multiple meanings including corn cobs and male swans.
Corn cobs are the unsung heroes of industry—they're used to make charcoal, clean metal parts, process seeds, and even create biofuel, which means most cobs never go to waste anymore.
