Open a fresh page (5)
I believe the answer is:
agape
'open' is the definition.
(similar in meaning)
'a fresh page' is the wordplay.
'fresh' indicates anagramming the letters.
'page' anagrammed gives 'gape'.
'a'+'gape'='AGAPE'
(Other definitions for agape that I've seen before include "love feast" , "ecclesiastical feast" , "love a Christian shows" , "Christian's love" , "Christian feast" .)
