Spicy Heat Is Not a Taste at All
Spicy means strongly flavoured or hot with chilli. The burning sensation is pain, not a flavour detected by taste buds.
Spicy means strongly flavoured with spices, or hot with chilli heat. Chilli heat is not a taste: capsaicin binds to TRPV1, the receptor that normally detects actual heat and physical damage, so the brain reports burning even though nothing is hot. That is why milk helps and water does not — capsaicin dissolves in fat, not water. *Spicy* also means slightly scandalous, from the idea of something with a sharp edge to it.

Why chilli burns
- Capsaicin binds to TRPV1, the heat and pain receptor
- The brain reads it as actual burning, though nothing is hot
- Milk works because capsaicin dissolves in fat
- Water spreads it around the mouth instead of removing it
- Birds are unaffected — their receptors do not respond, which helps chilli seeds disperse
From *spice*, Old French *espice*, from Latin *species*, plus the adjective suffix *-y*.
Is spiciness a taste?
No. Capsaicin activates the receptor for heat and pain, so the sensation is closer to a mild burn than to a flavour.
Why does milk help but water not?
Capsaicin dissolves in fat, so the fat in milk carries it away. Water simply spreads it around the mouth.
