York, say, has no hotel, but it does feature this (4)
I believe the answer is:
ouse
'it does feature this' is the definition.
The definition suggests a singular noun which matches the answer.
'york say has no hotel' is the wordplay.
'york say' becomes 'house' (as in the House of York, English royal house).
'has no' suggests deleting specific letters.
'hotel' becomes 'h' (phonetic alphabet: alpha, bravo, charlie etc.).
'house' with 'h' taken away is 'OUSE'.
'but' is the link.
(Other definitions for ouse that I've seen before include "Norfolk river" , "N English river (and S English river)" , "Name of river in Sussex or Yorkshire" , "One of several rivers" , "River at Bedford" .)
