High-caste Indians at home, entertained by composer (8)
I believe the answer is:
brahmins
'high-caste indians' is the definition.
I can't judge whether this defines the answer.
'home entertained by composer' is the wordplay.
I cannot really understand how this works, but
'home' could be 'in' ('he's home' can mean 'he's in') and 'in' is located in the answer.
'composer' could be 'brahms' (Brahms is an example) and 'brahms' is located in the remaining letters.
This accounts for all the letters.
This explanation may well be incorrect...
'at' acts as a link.
Can you help me to learn more?
(Other definitions for brahmins that I've seen before include "Members of the highest or priestly Hindu caste" , "Priests of the Hindu religion" , "Priestly types" , "Superior types" .)
