sever

I'm a little stuck... Click here to teach me more about this clue!

'cut off' is the definition.
(to sever is to cut)

'seafront always' is the wordplay.
'seafront' becomes 's' (this could be a standard abbreviation which I don't know about).
'always' becomes 'ever' (synonyms).
's'+'ever'='SEVER'

Can you help me to learn more?
