Carry Mike in Ford van? (8)
I believe the answer is:
transmit
'carry' is the definition.
(I know that carry is a kind of communicate)
'mike in ford van?' is the wordplay.
'mike' becomes 'M' (phonetic alphabet: alpha, bravo, charlie etc.).
'in' means one lot of letters goes inside another.
'ford van?' becomes 'transit' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'm' inserted inside 'transit' is 'TRANSMIT'.
Can you help me to learn more?
(Other definitions for transmit that I've seen before include "Send from one place to another" , "Pass on (message)" , "F. name; Hamlet (anag.)" , "Send (a radio message)" , "Send from one to another, electronically say" .)
