French maid turns up - the French turn to peer? (7)
I believe the answer is:
ennoble
'turn to peer?' is the definition.
(I've seen this before)
'french maid turns up the french' is the wordplay.
'french maid' becomes 'bonne' (I've seen this in other clues).
'turns up' shows that the letters should be reversed in order.
'the french' becomes 'le' ('the' in French).
'bonne' reversed gives 'ennob'.
'ennob'+'le'='ENNOBLE'
(Other definitions for ennoble that I've seen before include "Elevate with a title" , "Make a count, perhaps" , "Dignify" , "Aggrandise" , "Noel Ben (anag)" .)
