The kind of room a chanteuse needs? (4)
I believe the answer is:
ante
'the kind of room' is the definition.
(I've seen this in another clue)
'a chanteuse needs?' is the wordplay.
'needs?' says the answer is hidden in the clue (I've seen 'needs' mean this).
'ANTE' can be found hidden inside 'chanteuse'.
(Other definitions for ante that I've seen before include "Pre-deal stake" , "Stake, bet" , "Stake put up by a poker-player before receiving cards" , "Betting stake" , "Opening bet" .)
