'vitriol?' is the definition.
I know nothing about this answer so I can't tell whether this works.
'vitriol?' is the wordplay.
I cannot really see how this works, but
'vitriol?' could be 'acid' (vitriol is a kind of acid) and 'acid' is found within the answer.
The remaining letters 'remarks' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
