Inside course belongs to us (4)
I believe the answer is:
ours
'us' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.
'inside course belongs' is the wordplay.
'inside' indicates the answer is hidden within the clue.
'OURS' is hidden within 'course belongs'.
'to' is the link.
Can you help me to learn more?
(Other definitions for ours that I've seen before include "What we share" , "Relating or belonging to us" , "British" , "Belong to us both" , "The French bear" .)
