Limited or confined (10)
I believe the answer is:
restricted
I believe this clue is a double definition.
'limited' is the first definition.
(similar in meaning)
'confined' is the second definition.
(restricting is a kind of confining)
(Other definitions for restricted that I've seen before include "Limited in scope" , "Small - exclusive" , "Limited in extent" , "to be kept from general circulation" .)
