His daughter appeared in film - and managed to ensnare Yankee (4)
I believe the answer is:
ryan
'his daughter appeared in film' is the definition.
I don't know anything about this answer so I cannot judge whether this works.
'managed to ensnare yankee' is the wordplay.
'managed' becomes 'ran' (both can mean organised or was in charge of).
'to ensnare' is an insertion indicator.
'yankee' becomes 'Y' (phonetic alphabet: alpha, bravo, charlie etc.).
'ran' enclosing 'y' is 'RYAN'.
'and' is the link.
Can you help me to learn more?
(Other definitions for ryan that I've seen before include "Boy" , "Irishman" , "Gosling, perhaps" , "one associated with private saving account" , "US private" .)
