Agreeing neat signs are wrong (9)

I believe the answer is:

assenting

'agreeing' is the definition.
(synonyms)

'neat signs are wrong' is the wordplay.
'are wrong' indicates anagramming the letters.
'neat'+'signs'='neatsigns'
'neatsigns' with letters rearranged gives 'ASSENTING'.

(Other definitions for assenting that I've seen before include "Saying yes" , "Agreeing" .)

I've seen this clue in The Daily Express.
