cave from (Middle English):
Latin cavus, ‘hollow’, is the origin of a number of English words, including cave, cavern (Late Middle English), cavity (mid 16th century), and excavate (late 16th century). Concave (Late Middle English) is from cavus preceded by con ‘with’, while convex (late 16th century) is from the Latin for ‘vaulted, arched’. In the days when more people knew Latin, there was a second English word spelled cave. This one, pronounced kah-vay, meant ‘beware!’, and was used from the mid 19th century by schoolchildren to warn their friends that a teacher was coming.
