Clearly, manifestly (7)
I believe the answer is:
plainly
I believe this clue is a double definition.
'clearly' is the first definition.
(synonyms)
'manifestly' is the second definition.
(I know that manifestly can be written as plainly)
(Other definitions for plainly that I've seen before include "In unconcealed fashion" , "Clearly" , "Simply" , "... without embellishment" , "obviously" .)
