'just what apparently a' is the definition.
I can't tell whether this defines the answer.

'skinhead isn't' is the wordplay.
'skinhead' becomes 's' (head letter of 'skin').
'isn't' becomes 'aint' (non-standard version of 'isn't').
's'+'aint'='SAINT'

Can you help me to learn more?

(Other definitions for saint that I've seen before include "paragon!" , "Holy person" , "Very virtuous person" , "Beatified person" , "Good woman" .)
