Go away from Sweden and study intensively (5)
I believe the answer is:
scram
'go away' is the definition.
(scramming is a kind of going away)
'sweden and study intensively' is the wordplay.
'sweden' becomes 's'.
'and' means one lot of letters go next to another.
'study intensively' becomes 'cram' (I've seen this before).
's'+'cram'='SCRAM'
'from' is the link.
(Other definitions for scram that I've seen before include "In slang, go away and beat it" , "Clear off!" , "Vamoose" , "Scarper" , "Shoo!" .)
