The word "visually" is built upon the Latin foundation of sight. Its core, visu, originates from the Latin past participle visus of the verb vidēre, meaning "to see," which itself traces back to the Proto-Indo-European root weid-, meaning "to see" or "to know." The suffix -al was attached to form the adjective "visual," meaning "pertaining to sight." Finally, the Old English adverbial suffix -ly was added, creating "visually" to describe something done in a manner related to or perceived by vision. This etymological journey from the concrete act of seeing to the abstract concept of visual perception illustrates the development of language to describe sensory experience.
