The little chap always has a kiss for mum (3)
I believe the answer is:
max
'the little chap always' is the definition.
I can't tell whether this definition defines the answer.
'a kiss for mum' is the wordplay.
'a kiss' becomes 'x' (X can represent a kiss).
'for' is a charade indicator (letters next to each other) (I've seen this in other clues).
'mum' becomes 'ma' (ma can mean mother).
'x' after 'ma' is 'MAX'.
'has' acts as a link.
Can you help me to learn more?
(Another definition for max that I've seen is " The greatest".)
