Communicator that is twice involved in constitutional address (6-6)
I believe the answer is:
walkie-talkie
'communicator' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.
'that is twice involved in constitutional address' is the wordplay.
I cannot quite understand how this works, but
'constitutional' could be 'walk' (I've seen this in another clue) and 'walk' is found in the answer.
'address' could be 'talk' (both can mean a formal speech or presentation) and 'talk' is found in the answer.
'that is' could be 'ie' (short for Latin 'id est', 'that is') and 'ie' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for walkie-talkie that I've seen before include "Two way radio" , "Portable communication device" , "Portable two-way radio" .)
