Name a redheaded former spouse (3)
I believe the answer is:
rex
'name' is the definition.
Both the definition and answer are singular nouns.
Maybe you can see a link between them that I don't see?
'a redheaded former spouse' is the wordplay.
'a redheaded' becomes 'r' (this might be a standard abbreviation of which I'm unaware).
'former spouse' becomes 'ex'.
'r'+'ex'='REX'
Can you help me to learn more?
(Other definitions for rex that I've seen before include "See 6" , "King (L.)" , "Part of official title of a king" , "Dog's name; king" , "Oedipus - -" .)
