Chilly, wintry (4)
I believe the answer is:
cold
I believe this clue is a double definition.
'chilly' is the first definition.
(I've seen this before)
'wintry' is the second definition.
(similar in meaning)
(Other definitions for cold that I've seen before include "Lacking affection" , "Chill" , "Chilly; minor ailment" , "Unfriendly" , "Stand-offish" .)
