Reading made it clear (7)
I believe the answer is:
recital
'reading' is the definition.
(I know that reading can be written as recital)
'made it clear' is the wordplay.
'made' indicates anagramming the letters.
'it'+'clear'='itclear'
'itclear' with letters rearranged gives 'RECITAL'.
(Other definitions for recital that I've seen before include "Concert by soloist" , "Musician's performance" , "One's performance" , "Chamber music concert" , "Narrative" .)
