I quit idly, wandering in fluid state (9)

I believe the answer is:

liquidity

'fluid state' is the definition.
(I know this)

'i quit idly wandering' is the wordplay.
'wandering' is an anagram indicator.
'i'+'quit'+'idly'='iquitidly'
'iquitidly' is an anagram of 'LIQUIDITY'.

'in' acts as a link.

I've seen this clue in The Guardian.
