Close relative of badger crossing river (7)
I believe the answer is:
brother
This clue could be a double definition.
'close relative' is the first definition.
(I've seen this before)
'badger crossing river' is the second definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
'of' acts as a link.
Can you help me to learn more?
(Other definitions for brother that I've seen before include "Eg, monk, friar" , "Relation" , "Male sibling" , "Fellow-member" , "Trade unionist" .)
