There aren't many for whom I might leave the wife! (3)
I believe the answer is:
few
'wife' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for few that I've seen before include "Hardly anyone" , "Considerable number, ironically" , "Only one or two" , "Indefinite small amount" , "'''Many are called but ... are chosen'' (Bible) (3)'" .)
