Girl, one going after boy from South Asia (7)
I believe the answer is:
bengali
'south asia' is the definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
'girl one going after boy' is the wordplay.
'girl' becomes 'gal' ().
'one' becomes 'i' (Roman numeral).
'going after' means one lot of letters go next to another.
'boy' becomes 'ben' (boy's name).
'gal'+'i'='gali'
'gali' put after 'ben' is 'BENGALI'.
'from' is the link.
Can you help me to learn more?
(Other definitions for bengali that I've seen before include "resident in Calcutta?" , "Ethnic group and language of NE Indian subcontinent" , "Asian language" , "foreign language" , "Subcontinental" .)
