I believe the answer is:

prodigal son

I'm a little stuck... Click here to teach me more about this clue!

'pig-lad restored with touch of repentance and so on?' is the definition.
I don't know anything about this answer so I can't tell whether this works.

'pig-lad restored with touch of repentance and so on?' is the wordplay.
'restored with' indicates anagramming the letters.
'touch of' indicates taking the first letters.
'and' is a charade indicator (letters next to each other).
'on?' becomes 'on' ().
The initial letter of 'repentance' is 'r'.
'pig'+'lad'='piglad'
'r' after 'so' is 'sor'.
'piglad' anagrammed with 'sor' makes 'prodigals'.
'prodigals'+'on'='PRODIGAL SON'

Can you help me to learn more?
