A bird egg almost covers a bit of flesh (5)
I believe the answer is:
eagle
'a bird' is the definition.
(eagle is a type of bird)
'egg almost covers a bit of flesh' is the wordplay.
'almost' means to remove the last letter (most of the word but not all of it).
'covers' means one lot of letters goes inside another.
'bit of flesh' becomes 'le' (I can't explain this - if you can you should believe this answer much more).
'egg' with its last letter taken off is 'eg'.
'eg' going around 'a' is 'eag'.
'eag'+'le'='EAGLE'
Can you help me to learn more?
(Other definitions for eagle that I've seen before include "Bird of prey, may be golden" , "part of round that's exceptional" , "standard for the military is seen" , "somewhat under par" , "born hunter" .)
