Other forms: teacups
A teacup is a small china cup with a saucer. Thinner than a mug, and it goes cold far faster.
The thinness is deliberate, since fine bone china was believed to improve the taste and certainly improves the occasion. The handle exists because the cups came from China without one and Europeans found them too hot to hold. Britain has largely moved to mugs for everyday drinking and kept teacups for visitors. A storm in a teacup is a great fuss about something trivial.
