Visitant comes from Latin visitantem, present participle of visitare ('to go to see, visit'), a frequentative of visere ('to behold'), from videre ('to see'). In current use it is a noun and adjective meaning "a visitor, especially a supernatural one or a migratory bird". That sense is explained by the older material without requiring a speculative semantic step: the inherited or borrowed base supplies the field of meaning, while the English formation fixes its modern role. The -ing ending supplies a participial or action-noun shape. A frequentative element in the history points to repeated, habitual, or intensified action. The historical chain includes Latin visitare, Latin visere, and Latin videre. Related English forms include visit, visitation, and visitor. For dictionary purposes, the important point is the continuity between the older form, the route into English, and the present lexical sense.
