Spanish aunt in fur can be supplied to capacity (8)
I believe the answer is:
satiable
'be supplied to capacity' is the definition.
I can't tell whether this defines the answer.
'spanish aunt in fur' is the wordplay.
'spanish aunt' becomes 'tia' ('aunt' in Spanish).
'in' indicates putting letters inside.
'fur' becomes 'sable' (sable is a kind of fur).
'tia' put inside 'sable' is 'SATIABLE'.
'can' acts as a link.
Can you help me to learn more?
(Another definition for satiable that I've seen is " can be filled to capacity".)
