Elm Road cut off at both ends? (4)
I believe the answer is:
tree
'elm' is the definition.
(thesaurus)
'road cut off at both ends?' is the wordplay.
'road' becomes 'street' (street is a kind of road).
'cut off at both ends?' says to take the centre (the edge letters are removed).
The middle letters of 'street' are 'TREE'.
(Other definitions for tree that I've seen before include "May" , "eg Rowan" , "Tall, woody plant" , "Plant with trunk (which families have)" , "Large shrub; family line" .)
