Plain, evident (5)
I believe the answer is:
overt
I believe this clue is a double definition.
'plain' is the first definition.
(I've seen this in other clues)
'evident' is the second definition.
(I've seen this before)
(Other definitions for overt that I've seen before include "Plainly apparent" , "Not locked away" , "____ is able to be seen" , "Open and unconcealed" , "Openly displayed" .)
