Wired: “Taxi was in the forefront” (6)
I believe the answer is:
cabled
'wired' is the definition.
('cable' can be a synonym of 'wire')
'taxi was in the forefront' is the wordplay.
I cannot really understand how this works, but
'taxi' could be 'cab' (synonyms) and 'cab' is present in the answer.
The remaining letters 'led' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Another definition for cabled that I've seen is " Sent a message".)
