Distinguish between archer and old man in craft (4,5)

'distinguish' is the definition.
(I know that distinguish can be written as tell apart)

'archer and old man in craft' is the wordplay.
'archer' becomes 'tell' (folk hero William Tell).
'and' is a charade indicator (letters next to each other).
'old man' becomes 'pa' (both can mean someone's father).
'in' means one lot of letters goes inside another.
'craft' becomes 'art' (both can mean cunning or trickery).
'pa' inserted within 'art' is 'apart'.
'tell'+'apart'='TELL APART'

'between' is the link.
