Large cave (6)

Ross

I believe the answer is:

cavern

'large cave' is the definition.
(I've seen this before)

This is the entire clue.

(Other definitions for cavern that I've seen before include "Subterranean chamber" , "Large underground hollow" , "Large 24 chamber" , "vast enclosed space" , "Craven in a cave" .)

I've seen this clue in The Times.
