Father acquires a container showing signs of age (6)
I believe the answer is:
patina
'signs of age' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
'father acquires a container' is the wordplay.
'father' becomes 'pa' (pa can mean dad or father).
'acquires' indicates putting letters inside.
'container' becomes 'tin' (tin is a kind of container).
'a'+'tin'='atin'
'pa' going around 'atin' is 'PATINA'.
'showing' acts as a link.
Can you help me to learn more?
(Other definitions for patina that I've seen before include "Fine coating on surface" , "Film on copper or bronze" , "Brownish surface film on old bronze" , "Distinctive surface acquired over time" , "Film forming on bronze" .)
