Car freshener scent (4)
I believe the answer is:
pine
'car freshener scent' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for pine that I've seen before include "Evergreen conifer" , "Long for the conifer?" , "Tree, waste away" , "Scots fir" , "Yearn for evergreen tree" .)
