cousin

I'm a little stuck... Click here to teach me more about this clue!

'relative' is the definition.
(cousin is a kind of relative)

I can't explain the rest of the clue.

(Other definitions for cousin that I've seen before include "Aunt's/uncle's child" , "one in my family" , "Child of a parent's sibling, say" , "Family relative" , "An aunt's or uncle's child" .)

I've seen this clue in The Hindu.
