Common conifer (4)
I believe the answer is:
pine
'common conifer' 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 "Yen - tree" , "Long - timber" , "Yearn for evergreen tree" , "Fir tree; languish" , "Coniferous tree" .)
