Crow adopted by some youths (6)
I believe the answer is:
hoodie
'crow' is the definition.
(I've seen this before)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for hoodie that I've seen before include "Crow; cowled youth" , "Casual jacket" , "Sweatshirt with head-covering" , "Youth's top" , "Form of jacket; youth wearing one" .)
