Singer-songwriter (3,5)
I believe the answer is:
bob dylan
I believe this is a double definition.
'singer' is the first definition.
(I know that Bob Dylan is a singer)
'songwriter' is the second definition.
(I know that Bob Dylan is a songwriter)
(Other definitions for bob dylan that I've seen before include "Singer-songwriter, born Robert Allen Zimmerman in 1941" , "Songwriter, winner of the 2016 Nobel Prize for Literature" , "Singer" , "US singer/songwriter is nobly bad, curiously" , "US protest singer/songwriter" .)
