Wolf inhabiting lair, most dapper (7)
I believe the answer is:
neatest
'most dapper' is the definition.
(dapper can mean neat or stylish)
'wolf inhabiting lair' is the wordplay.
'wolf' becomes 'eat' (wolf can informally mean to eat or consume).
'inhabiting' indicates putting letters inside (I've seen this in other clues).
'lair' becomes 'nest' (an animal's nest).
'eat' inserted inside 'nest' is 'NEATEST'.
(Other definitions for neatest that I've seen before include "best-looking desk, say?" , "Most smart" , "Most orderly" , "Most tidy" , "Seat ten (anag)" .)
