the.com/taste bud

means A cluster of sensory receptor cells on the tongue (and nearby surfaces) that detects chemicals in food and signals flavors like sweet, salty, sour, bitter, and umami to the brain.

from Straightforward English compounding, not borrowed finery: 'taste' traces back through French to Latin 'taxare,' meaning to touch or assess, while 'bud' comes from Old English/Germanic roots for a small swelling shoot, like a flower about to open. Scientists in the 1800s, peering through microscopes at the tiny onion-shaped clusters on the tongue's surface, simply named what they saw — a bud whose job is tasting. No myth needed; the word is as literal as the biology.
