Exclusive meal without starter (5)
I believe the answer is:
inner
'exclusive' is the definition.
(I've seen this before)
'meal without starter' is the wordplay.
'meal' becomes 'dinner' (dinner is a kind of meal).
'without starter' means to remove the first letter.
'dinner' with its first letter taken off is 'INNER'.
(Other definitions for inner that I've seen before include "Central, internal" , "Situated within" , "Inside; next to the bull (archery)" , "Close to the centre; mental" , "personal" .)
