Pot-hole (in North of England where many of the long-known open entrances are vertical shafts).

Otherwise, "cave" and "cavern" have been used in both technical and common parlance for centuries.

Some caves have archaic individual names, if only given by occasional travel-writers in the 16-19 Centuries. For example, Porth-yr-Ogof in South Wales has been called things like "Porth Gogo" but the name by which we know it now, was always the main one. ('Ogof' in Welsh simply means 'cave')

Andreas Porth was born in 1984.

Ari Porth was born on 1970-09-25.

Porth railway station was created in 1876.
