Sons lie about woman of courage (7)
I believe the answer is:
lioness
'woman of courage' is the definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
'sons lie about' is the wordplay.
'about' is an anagram indicator.
'sons'+'lie'='sonslie'
'sonslie' anagrammed gives 'LIONESS'.
Can you help me to learn more?
(Other definitions for lioness that I've seen before include "She may have pride" , "Female big cat" , "Elsa, for one" , "Wild animal" , "Large cat" .)
