Received with thanks, boy (5)
I believe the answer is:
taken
'received' is the definition.
(taking is a kind of receiving)
'with thanks boy' is the wordplay.
'with' says to put letters next to each other.
'thanks' becomes 'ta' (UK informal version of 'thank you').
'boy' becomes 'ken' (man's name).
'ta' put next to 'ken' is 'TAKEN'.
(Other definitions for taken that I've seen before include "Charmed" , "Removed; occupied" , "Seized" , "Captured" , "Removed (from a place)" .)
