One who assists eating English fare (9)
I believe the answer is:
passenger
'fare' is the definition.
(thesaurus)
'one who assists eating english' is the wordplay.
'one who assists' becomes 'passer' (I can't justify this - if you can you should give a lot more credence to this answer).
'eating' means one lot of letters goes inside another.
'english' becomes 'eng' (abbreviation).
'passer' enclosing 'eng' is 'PASSENGER'.
Can you help me to learn more?
(Other definitions for passenger that I've seen before include "One travelling" , "burden to the team" , "Rider" , "Traveller in a vehicle, not the driver" , "One on team doing little effective work" .)
