Uncle from America has degree in dance (5)
I believe the answer is:
samba
'dance' is the definition.
(Brazilian dance)
'uncle from america has degree' is the wordplay.
'from' indicates named letters should be taken away.
'america' becomes 'uncle sam' (I've seen this before).
'has degree' becomes 'ba' (I am not sure about this - if you are sure you should believe this answer much more).
'unclesam' with 'uncle' taken out is 'sam'.
'sam'+'ba'='SAMBA'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for samba that I've seen before include "This ambassador's > brisk steps" , "it was launched in Brazil" , "Lively ballroom dance from Brazil" , "Dance, originally from Brazil" , "Dance music" .)
