Address English females and finish with one (7)
I believe the answer is:
effendi
'address' is the definition.
(I have seen 'respectable address' mean 'effendi' so perhaps 'address' could also mean 'effendi')
'english females and finish with one' is the wordplay.
'english' becomes 'e' (abbreviation).
'females' becomes 'ff' (an abbreviation for female written twice).
'and' is a charade indicator (letters next to each other).
'finish with' becomes 'end' (synonyms. I am not sure about the 'with' bit.).
'one' becomes 'I' (Roman numeral).
'e'+'ff'+'end'+'i'='EFFENDI'
Can you help me to learn more?
(Other definitions for effendi that I've seen before include "foreigner of standing" , "Respected Arab" , "educated Arab?" , "Turkish man respectfully" , "Levantine gent?" .)
