Tree seen if turning to the right (3)
I believe the answer is:
fir
'tree' is the definition.
(fir tree is a kind of tree)
'if turning to the right' is the wordplay.
'turning to' indicates anagramming the letters (the letters can turn into other words).
'the right' becomes 'r' (common abbreviation).
'if' anagrammed gives 'fi'.
'fi'+'r'='FIR'
'seen' is the link.
(Other definitions for fir that I've seen before include "Kind of cone-bearing tree" , "wood" , "Evergreen tree for Gaelic men" , "Evergreen tree for Irish men?" , "Evergreen conifer" .)
