Receiver regularly takes money to Arabs (6)
I believe the answer is:
aerial
'receiver' is the definition.
(I have seen 'Receiver of signal ' mean 'aerial' so perhaps 'receiver' could also mean 'aerial')
'regularly takes money to arabs' is the wordplay.
'regularly' indicates alternate letters (regularly take one letter, leave next etc.).
'money' becomes 'l' (L can mean 'pounds').
'to' is a charade indicator (letters next to each other) (I've seen this in other clues).
'arabs' becomes 'ria' (I can't explain this - if you can you should believe this answer much more).
The alternate letters of 'takes' are 'ae'.
'l' after 'ria' is 'rial'.
'ae'+'rial'='AERIAL'
Can you help me to learn more?
(Other definitions for aerial that I've seen before include "Antenna for capturing radio or TV signals" , "Device to send and receive radio signals" , "Signal receiver" , "What may receive" , "Device for sending or receiving signals" .)
