Eloquent, sliding in car on ice (10)

I believe the answer is:

ciceronian

'eloquent' is the definition.
(like the Roman statesman Cicero)

'sliding in car on ice' is the wordplay.
'sliding' indicates an anagram (letters sliding around).
'in'+'car'+'on'+'ice'='incaronice'
'incaronice' is an anagram of 'CICERONIAN'.

I've seen this clue in The Guardian.
