What does inaccessible mean?
Inaccessible means that something cannot be reached, entered, viewed, obtained, or understood. The word is commonly used for physical locations and routes, as in an inaccessible mountain or an inaccessible building, but it also describes restricted or unavailable information, documents, services, and opportunities. An inaccessible website, for example, may be unavailable because of technical problems or because users are denied permission to enter it. In social and institutional contexts, describing something as inaccessible can imply that people are deliberately excluded. The related noun inaccessibility refers to the condition or quality of being inaccessible. Although the word is more formal than phrases such as “out of reach” or “cannot get into,” it is useful when describing barriers, restrictions, and the failure of access.

Where does inaccessible come from?
The word is formed from the prefix in-, meaning “not,” and accessible, “able to be reached or approached.” Both elements ultimately relate to Latin accedere, “to go to, approach, or enter,” the source of English access and accessible. The resulting form entered English in the nineteenth century and developed its modern sense of being unreachable or unavailable.
