Exclusive meal daughters missed (5)
I believe the answer is:
inner
'exclusive' is the definition.
(I've seen this before)
'meal daughters missed' is the wordplay.
'meal' becomes 'dinner' (dinner is a kind of meal).
'daughters' becomes 'd' (genealogical abbreviation for daughters).
'missed' indicates named letters should be taken away.
'dinner' with 'd' removed is 'INNER'.
(Other definitions for inner that I've seen before include "Private, not expressed" , "Situated within" , "Not quite bull's-eye" , "(Of thoughts) intimate - (of circles) privileged" , "just missing the gold" .)
