A striking tree? (5)
I believe the answer is:
birch
This clue could be a double definition.
'a striking' is the first definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.
'tree?' is the second definition.
(I know that birch is a type of tree)
Can you help me to learn more?
(Other definitions for birch that I've seen before include "Flog" , "Wood" , "Tree with silvery bark" , "Flogging rod" , "Hardy tree" .)
