Rose's joint (3)
I believe the answer is:
hip
This might be a double definition.
'rose's' is the first definition.
Both the answer and definition are adjectives. Perhaps there's a link between them I don't understand?
'joint?' is the second definition.
(part of body)
Can you help me to learn more?
(Other definitions for hip that I've seen before include "Joint; rose fruit" , "Slangily trendy part of body" , "Leg joint" , "In slang, trendy or stylish like body joint" , "Trendy bodily joint?" .)
