the word 'visitable' is a modern english formation built upon the well-established verb 'visit'. the core verb 'visit' originates from latin visitare, meaning 'to go to see, to attend to', which itself is a frequentative form of visere, 'to view, to behold'. the suffix '-able', of latin origin via old french, is productively attached to verbs to create adjectives meaning 'capable of undergoing the action'. thus, the literal morphemic construction 'capable of being visited' directly and logically yields the modern meaning of a place being suitable or accessible for visitors.

Structure: visit + able visit (from latin visitare, frequentative of visere, meaning 'to go to see') + able (from latin -abilis, an adjective-forming suffix meaning 'capable of, fit for').
