Child from India in farm building (5)
I believe the answer is:
bairn
'child' is the definition.
(Scottish and northern English term for a child)
'india in farm building' is the wordplay.
'india' becomes 'i' (phonetic alphabet: alpha, bravo, charlie etc.).
'in' means one lot of letters goes inside another.
'farm building' becomes 'barn' (barn is a kind of farm building).
'i' placed within 'barn' is 'BAIRN'.
'from' acts as a link.
(Other definitions for bairn that I've seen before include "A Scottish child?" , "Scot. child" , "little one in Yorkshire" , "Child (of the North!)" , "Kid" .)
