Asian who returned to help in pub? (6)
I believe the answer is:
indian
'asian' is the definition.
(Indian is an example)
'returned to help in pub?' is the wordplay.
'returned' shows that the letters should be reversed in order.
'to help' becomes 'aid' ('aid' can be a synonym of 'help'**).
'in' indicates putting letters inside.
'pub?' becomes 'inn' (I've seen this before).
'aid' reversed gives 'dia'.
'dia' put within 'inn' is 'INDIAN'.
'who' acts as a link.
(Other definitions for indian that I've seen before include "One from the sub-continent" , "From Kolkata, perhaps" , "National" , "American aborigine" , "Nationality of Salman Rushdie" .)
