Would echo in the forest (4)
I believe the answer is:
'forest' is the definition.
(synonyms)
'would echo' is the wordplay.
I cannot really understand how this works, but
'would' could be 'd' (as in 'we'd' - 'we would') and 'd' is found within the answer.
The remaining letters 'woo' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'in the' is the link.
Can you help me to learn more?
(Other definitions for wood that I've seen before include "Dense growth of trees" , "What you might need to play golf" , "Large group of trees" , "Small forest; golf club" , "Old conductor" .)
