Go in for revolutionising the Internet at last (5)
I believe the answer is:
enter
'go in' is the definition.
(synonyms)
'revolutionising the internet at last' is the wordplay.
I cannot really understand how this works, but
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is found in the answer.
'internet' could be 'e' (I've seen this in other clues) and 'e' is found within the answer.
'last' could be 'e' (I've seen this in other clues) and 'e' is found within the answer.
This may be the basis of clue (or it may be nonsense).
'for' acts as a link.
Can you help me to learn more?
(Other definitions for enter that I've seen before include "Join (for the first time)" , "Enrol" , "Go in and put in the ledger" , "Come in - penetrate - record" , "Register formally as a participant" .)
