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' indicates putting letters inside.
'craft' becomes 'art' (both can mean cunning or trickery).
'pa' put into 'art' is 'apart'.
'tell'+'apart'='TELL APART'

'between' is the link.
