Dwelling for top people featured in communication (8)
I believe the answer is:
messuage
'dwelling' is the definition.
(legal term for a dwelling and outbuildings)
'for top people featured in communication' is the wordplay.
I cannot really understand how this works, but
'for top people' could be 'u' (upper-class, as in U and non-U language) and 'u' is found within the answer.
'communication' could be 'message' (message is a kind of communication) and 'message' is located in the remaining letters.
This accounts for all the letters.
This may be the basis of clue (or it may be nonsense).
(Another definition for messuage that I've seen is " House with outbuildings and land (law)".)
