Deny working with English underprivileged (5)
I believe the answer is:
needy
'underprivileged' is the definition.
(I've seen this in another clue)
'deny working with english' is the wordplay.
'working with' is an anagram indicator (working with the letters).
'english' becomes 'E' (abbreviation).
'deny' anagrammed with 'e' makes 'NEEDY'.
(Other definitions for needy that I've seen before include "Poor; indigent" , "Poor; wanting affection" , "Wanting attention" , "Impoverished" , "Necessitous" .)
