Recipient to talk English twice (9)
I believe the answer is:
addressee
'recipient' is the definition.
(addressee is a kind of recipient)
'talk english twice' is the wordplay.
'talk' becomes 'address' (I've seen this in another clue).
'english' becomes 'E' (abbreviation).
'twice' indicates the doubling of some letters.
'e' doubled is 'ee'.
'address'+'ee'='ADDRESSEE'
'to' is the link.
(Other definitions for addressee that I've seen before include "One contacted" , "Intended recipient of letter" , "Recipient of mail" , "Recipient of post" , "The person to whom letter is delivered" .)
