European gets Irishman maybe back on message (5)
I believe the answer is:
'message' is the definition.
(email is a type of message)
'european gets irishman maybe back' is the wordplay.
'european' becomes 'E' (abbreviation e.g. EU).
'gets irishman maybe' becomes 'liam' (I am not sure about this - if you are sure you should believe this answer much more).
'back' says the letters should be written in reverse.
'liam' reversed gives 'mail'.
'e'+'mail'='EMAIL'
'on' is the link.
Can you help me to learn more?
(Other definitions for email that I've seen before include "Messages via the internet" , "Internet-borne communication" , "Electronic communication" , "Message sent via computer" , "Electronic message" .)
