Mother trapped in fib about messages (1-4)
I believe the answer is:
'mother trapped in fib about messages' is the definition.
I can't judge whether this definition defines the answer.
'mother trapped in fib about' is the wordplay.
'mother' becomes 'ma' (Ma is another word for mother or mum).
'trapped in' is an insertion indicator.
'fib' becomes 'lie' (I've seen this in another clue).
'about' says the letters should be written backwards.
'lie' backwards is 'eil'.
'ma' put within 'eil' is 'E-MAIL'.
Can you help me to learn more?
(Other definitions for e-mail that I've seen before include "Send a message" , "A lime (anag.)" , "Online correspondence" , "Online message" , "Messages via the internet" .)
