neologisms

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

'showing updated terms' is the definition.
I can't judge whether this defines the answer.

'one fresh record one's writing' is the wordplay.
'fresh' indicates an anagram.
'record' becomes 'log' (log is a kind of record).
'one's' becomes 'I's' (Roman numeral).
'writing' becomes 'ms' (abbreviation for manuscript).
'one' is an anagram of 'neo'.
'neo'+'log'+'is'+'ms'='NEOLOGISMS'

Can you help me to learn more?

(Another definition for neologisms that I've seen is " Modern bits of language".)

I've seen this clue in The Independent.
