Discernible, manifest (7)
I believe the answer is:
evident
This clue is a double definition.
'discernible' is the first definition.
(I've seen this in another clue)
'manifest' is the second definition.
(I know that manifest can be written as evident)
(Other definitions for evident that I've seen before include "'Plain, apparent (7)'" , "Obvious - 1 across" , "Quite obvious, easy to see" , "Obvious, may be plainly seen" , "Clearly discernible" .)
