Family member from India on board? (3)
I believe the answer is:
sis
'family member' is the definition.
(short for sister)
'india on board?' is the wordplay.
I cannot quite see how this works, but
'india' could be 'i' (phonetic alphabet: alpha, bravo, charlie etc.) and 'i' is found in the answer.
'on board?' could be 'ss' (I've seen this in other clues) and 'ss' is located in the remaining letters.
This accounts for all the letters.
This explanation may well be incorrect...
'from' is the link.
Can you help me to learn more?
(Other definitions for sis that I've seen before include "Secret Intelligence Service (abbreviation)" , "spies ..." , "Little sibling" , "Family member (informal)" , "relative" .)
