Din about Mr Hislop acquiring nationality (6)
I believe the answer is:
indian
'hislop acquiring nationality' is the definition.
I can't judge whether this defines the answer.
'din about mr' is the wordplay.
'about' indicates an anagram.
'mr' becomes 'ian' ().
'din' with letters rearranged gives 'ind'.
'ind'+'ian'='INDIAN'
Can you help me to learn more?
(Other definitions for indian that I've seen before include "IDA inn provided for this nationality" , "Native American or denizen of New Delhi, say" , "IDA inn provides for this nationally" , "Type of club, file, tea or summer" , "He's from 16 down" .)
