Make a world that’s fitting for US singer (10)
I believe the answer is:
meadowlark
'us singer' is the definition.
'meadowlark' can be an answer for 'singer' (meadowlark is a kind of birdanimal). I am not sure about the 'us' bit.
'make a world that's fitting' is the wordplay.
'that's fitting' is an anagram indicator (letters fit or arranged differently).
'make'+'a'+'world'='makeaworld'
'makeaworld' with letters rearranged gives 'MEADOWLARK'.
'for' is the link.
Can you help me to learn more?
(Other definitions for meadowlark that I've seen before include "Songbird" , "Bird" .)
