1. discernible. 2. open, conspicuous, manifest, unmistakable. Apparent, evident, obvious, patent all refer to something easily perceived. Apparent applies to that which can readily be seen or perceived: an apparent effort. Evident applies to that which facts or circumstances make plain: His innocence was evident. Obvious applies to that which is unquestionable, because of being completely manifest or noticeable: an obvious change of method. Patent, a more formal word, applies to that which is open to view or understanding by all: a patent error.
