Want to save money, showing frugality (10)
I believe the answer is:
abstinence
'frugality' is the definition.
The answer and definition can be both human attributes as well as being singular nouns.
Maybe there's an association between them I don't understand?
'want to save money' is the wordplay.
'want' becomes 'absence' (I've seen this before).
'to save' means one lot of letters goes inside another.
'money' becomes 'tin' (I've seen this before).
'absence' enclosing 'tin' is 'ABSTINENCE'.
'showing' acts as a link.
Can you help me to learn more?
(Other definitions for abstinence that I've seen before include "Not drinking" , "Practice of refraining from indulging an appetite" , "Temperance" , "Non-partaking (of liquor)" , "Staying away from" .)
