Dispatch, transmit (4)
I believe the answer is:
send
I believe this clue is a double definition.
'dispatch' is the first definition.
(I know that dispatch is a kind of send)
'transmit' is the second definition.
(I know that transmit can be written as send)
(Other definitions for send that I've seen before include "Despatch, remit" , "and 2: Advise" , "Sentence to a prison term" , "broadcast" , "Forward" .)
