'article for study returned in protective cover' is the definition.
I can't judge whether this defines the answer.

'article for study returned' is the wordplay.
'article' becomes 'a' (the indefinite article in English).
'for' becomes 'pro' (as in being 'pro' something).
'study' becomes 'den' (term for a study or office).
'returned' shows that the letters should be reversed in order.
'den' backwards is 'ned'.
'a'+'pro'+'ned'='APRONED'
