Amply cover own retreat? (7,4,4)
I believe the answer is:
feather ones nest
'amply cover own retreat?' is the definition.
I can't tell whether this defines the answer.
'cover own retreat?' is the wordplay.
I cannot really understand how this works, but
'cover' could be 'feather' (feather is a kind of cover) and 'feather' is found in the answer.
'retreat?' could be 'nest' (nest is a kind of retreat) and 'nest' is found in the answer.
The remaining letters 'ones' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for feather ones nest that I've seen before include "use down where you live?" , "What a chat may do!" , "Appropriate stuff" , "Enrich oneself" , "become richer" .)
