Is definite about names (10)

I believe the answer is:

identifies

'names' is the definition.
(I know this)

'is definite about' is the wordplay.
'about' indicates anagramming the letters.
'is'+'definite'='isdefinite'
'isdefinite' with letters rearranged gives 'IDENTIFIES'.

(Another definition for identifies that I've seen is " fingers".)

I've seen this clue in The Guardian.
