Parsing inflected forms may not always work as expected. If the following does not give the correct word, try Latin Words or Perseus.
vīsŭālis, e, adj. [visus], attained by sight (late Lat.): probatio, Cassiod. Var. 4, 51.
Hence, subst.: vīsŭālĭa, ĭum, n., the power of vision, Theod. Prisc. 4, 2.
Adv.: vīsŭālĭter, visibly (late Lat.), Cassiod. in Psa. 36, 29.
