A verruca is a small, hard, rough lump that grows on the skin of your foot, usually on the sole or the toes. It is caused by a virus, so it can pass from one person to another — which is why people catch them at swimming pools, showers and changing rooms, where bare feet touch wet floors. A verruca often has tiny black dots in the middle and can hurt when you stand or walk on it, because your body weight pushes it inwards instead of letting it stick out.

A verruca is really the same thing as a wart; the difference is only where it grows. English speakers say 'wart' for the ones on hands and fingers, and 'verruca' for the ones on the bottom of the foot. Americans mostly do not use this word at all — they say 'plantar wart'.

A verruca verruca其實跟wart是同一種東西is really the same thing as a wart；the difference差別only只是where it grows長的位置不同。English speakers英語人士say會用'wart'「wart」for the ones on hands and fingers講手上和手指的，and而用'verruca'「verruca」for the ones on the bottom of the foot講腳底的。Americans美國人mostly大多do not use this word at all根本不用這個字——they他們say會說'plantar wart'「plantar wart」。

In Britain and in many places that learned English from Britain, 'verruca' is the everyday word, used by parents and school teachers, not just doctors. Doctors also say 'verruca' in a wider way, for warts anywhere on the body, but that is technical use. The plural you will see in careful writing is 'verrucae', though many people simply say 'verrucas'.
