No-one at Cannes that could be common (4)

I believe the answer is:

noun

'that could be common' is the definition.
(common noun is a type of noun)

'no-one at cannes' is the wordplay.
'one at cannes' becomes 'un' ('one' in French, eg in Cannes).
'no'+'un'='NOUN'

(Other definitions for noun that I've seen before include "Word used as a name for something or person" , "Word identifying person, place or thing" , "Part of speech identifying a person, place or thing" , "Substantive word" , "Identifying word (common or proper)" .)

I've seen this clue in The Independent.
