Inappropriate French article expected (5)

I believe the answer is:

undue

'inappropriate' is the definition.
(similar in meaning)

'french article expected' is the wordplay.
'french article' becomes 'un' (indefinite article in French).
'expected' becomes 'due' (similar in meaning).
'un'+'due'='UNDUE'

(Other definitions for undue that I've seen before include "More than appropriate" , "Not warranted" , "Needless; excessive" , "Inappropriate - excessive" , "Unwarranted, inordinate" .)

I've seen this clue in The Mirror.
