It's meant to be read, so make it clear (7)
I believe the answer is:
article
'it's meant to be read' is the definition.
'make it clear' is the wordplay.
'make' indicates anagramming the letters.
'it'+'clear'='itclear'
'itclear' with letters rearranged gives 'ARTICLE'.
'so' is the link.
(Other definitions for article that I've seen before include "Recital (anag.)" , "Division" , "Definite or indefinite determiner" , "It may be the" , "A rewritten piece" .)
