Worker by Queen about to be receiver of signal (7)
I believe the answer is:
antenna
'receiver of signal' is the definition.
'antenna' can be an answer for 'receiver' (I've seen this before). I'm not sure about the 'of signal' bit.
'worker by queen about' is the wordplay.
'worker' becomes 'ant' (worker is a type of ant).
'by' is a charade indicator (letters next to each other).
'queen' becomes 'anne' (Queen Anne, 18th-century queen).
'about' says the letters should be written in reverse.
'anne' written backwards gives 'enna'.
'ant'+'enna'='ANTENNA'
'to be' is the link.
Can you help me to learn more?
(Other definitions for antenna that I've seen before include "one feels" , "Insect's feeler" , "Aerial - insect feeler" , "sensitive feeler" , "Radio aerial" .)
