What the poor don't have to be lent in extremes of poverty (6)
I believe the answer is:
plenty
'what the poor don't have to' is the definition.
I can't tell whether this definition defines the answer.
'lent in extremes of poverty' is the wordplay.
'in' means one lot of letters goes inside another.
'extremes of' says to hollow out the word (remove centre letters) (only the letters at the extremes of the word).
'poverty' with its centre removed is 'py'.
'lent' going inside 'py' is 'PLENTY'.
'be' acts as a link.
Can you help me to learn more?
(Other definitions for plenty that I've seen before include "A full supply - lots" , "Many" , "Copiousness" , "A great deal" , "Ample quantity" .)
