A London tree (6)
I believe the answer is:
poplar
This clue might be a double definition.
'a london' is the first definition.
Although both the answer and definition are singular nouns, I cannot understand how they can define each other.
'tree' is the second definition.
(poplar is a kind of tree)
Can you help me to learn more?
(Other definitions for poplar that I've seen before include "Tree of willow family" , "Tree - London district" , "Leaves producer" , "Tall tree (which may tremble?)" , "Tree with leaves that quiver" .)
