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

'assumed name' is the definition.
'moniker' can be an answer for 'name' (moniker can mean a name or pseudonym). I am unsure of the 'assumed' bit.

'spilt more ink' is the wordplay.
'spilt' is an anagram indicator.
'more'+'ink'='moreink'
'moreink' is an anagram of 'MONIKER'.

Can you help me to learn more?
