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

'unquantifiable' is the definition.
I don't know anything about this answer so I can't judge whether this works.

'damage done to angie and den it's' is the wordplay.
'damage done to' is an anagram indicator.
'and' is a charade indicator (letters next to each other).
'den'+'its'='denits'
'angie' put after 'denits' is 'denitsangie'.
'denitsangie' anagrammed gives 'INDESIGNATE'.
