Swedish youngster, partly attractive (5)
I believe the answer is:
dishy
'attractive' is the definition.
('dishy' can be similar in meaning to 'attractive')
'swedish youngster partly' is the wordplay.
'partly' indicates a hidden word.
'DISHY' can be found hidden inside 'swedish youngster'.
(Other definitions for dishy that I've seen before include "Informally good-looking, like plate?" , "Good-looking (colloq.)" , "Gorgeous" , "Handsome" , "Good-looking (informal)" .)
