Expected of the French and English (3)
I believe the answer is:
due
'expected' is the definition.
(similar in meaning)
'of the french and english' is the wordplay.
'of the french' becomes 'du' ('of the' in French).
'and' says to put letters next to each other.
'english' becomes 'e' (abbreviation).
'du'+'e'='DUE'
(Other definitions for due that I've seen before include "...more than one there [ROME]" , "Appropriate - fee - now owing" , "Expected; appropriate" , "Proper; owed" , "imminent" .)
