Hot articles Hoskins had knocked over in state (7)
I believe the answer is:
indiana
'state' is the definition.
(US state)
'hot articles hoskins had knocked over' is the wordplay.
'hot' becomes 'in' (both can mean fashionable).
'articles' becomes 'ana' ('an' and 'a', English indefinite articles).
'hoskins had' becomes 'I'd' (where the crossword setter is 'Hoskins').
'knocked over' shows that the letters should be reversed in order.
'ana'+'id'='anaid'
'anaid' backwards is 'diana'.
'in'+'diana'='INDIANA'
'in' acts as a link.
(Other definitions for indiana that I've seen before include "___ Jones, action hero created by George Lucas" , "American state" , "Character associated with the Temple of Doom" , "___ Jones (Raiders of the Lost Ark)" , "member of 2 [THE STATES]" .)
