Greek and German found in cave (6)
I believe the answer is:
grotto
'cave' is the definition.
(I've seen this before)
'greek and german' is the wordplay.
'greek' becomes 'gr'.
'and' is a charade indicator (letters next to each other).
'german' becomes 'otto' (I've seen this before).
'gr'+'otto'='GROTTO'
'found in' is the link.
(Other definitions for grotto that I've seen before include "Artificially or naturally ornamented cave" , "fancy underground area" , "Ornamental cave" , "A picturesque cave as in Lourdes (6)" , "(Imitation) cave" .)
