Heard lawmen in wood (5)
I believe the answer is:
copse
'wood' is the definition.
(a copse is a small wood)
'heard lawmen' is the wordplay.
I cannot really see how this works, but
'lawmen' could be 'cops' (cop is a kind of lawman) and 'cops' is found within the answer.
A single letter 'e' remains 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' acts as a link.
Can you help me to learn more?
(Other definitions for copse that I've seen before include "Harvested woodland" , "Small group of trees" , "Dense thicket of trees" , "Coppice" , "Piece of managed woodland" .)
