An archaic or dialect term, likely related to a type of plant or herb (possibly a variant of 'clove').
Possibly from Old French or Middle English, with uncertain etymology; may be a dialectal variant or corruption of 'clove' (the spice), though the connection is unclear and the word is rarely documented.
Words like 'colove' are linguistic fossils that appear in old texts and dictionaries but have lost all living use—they remind us that English is constantly shedding words, and for every 'selfie' or 'cryptocurrency' we add, dozens of old words die out completely.
