Pine to be like a dandy? (6)
I believe the answer is:
spruce
'pine' is the definition.
(spruce pine is a kind of pine)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for spruce that I've seen before include "Trim - conifer" , "Smart-looking sort of fir tree" , "Evergreen pyramid-shaped trees" , "tree with needle-like leaves" , "Evergreen pyramid-shaped tree" .)
