Manifest, evident (7)
I believe the answer is:
obvious
I believe this is a double definition.
'manifest' is the first definition.
(similar in meaning)
'evident' is the second definition.
(similar in meaning)
(Other definitions for obvious that I've seen before include "Perfectly plain and easy to understand" , "Perfectly plain and clear" , "Glaring" , "Easily perceived or understood" , "Self-evident" .)
