Very nearly new name, 1/100 (4)
'name 1100' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.
'very nearly new' is the wordplay.
I cannot really understand how this works, but
'very' could be 'v' (abbreviation) and 'v' is found within the answer.
an anagram of 'nearly' is 'eralyn' which is located in the answer.
'new' could be 'n' and 'n' is found in the answer.
This accounts for all the letters.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?

'new name 1100' is the definition.
I can't tell whether this defines the answer.
'very nearly' is the wordplay.
'very' becomes 'v' (abbreviation).
'nearly' becomes 'era' (I can't justify this - if you can you should believe this answer much more).
'v'+'era'='VERA'
