American uncle gets graduate to dance (5)
I believe the answer is:
samba
'dance' is the definition.
(Brazilian dance)
'american uncle gets graduate' is the wordplay.
'american uncle' becomes 'Sam' (Uncle Sam is a nickname for the USA).
'gets' says to put letters next to each other.
'graduate' becomes 'ba' (someone with a Bachelor of Arts degree).
'sam'+'ba'='SAMBA'
'to' is the link.
(Other definitions for samba that I've seen before include "Brazilian dance" , "South American dance" , "Latin dance" , "Dance music" , "moves from Brazil" .)
