The word "Ungowa" has an interesting history: It's a fabricated word which, according to Hollywood legend, was invented by some MGM studio writers in 1932. (1932 was the year Johnny Weissmuller's first Tarzan film - Tarzan the Ape Man - was shot at MGM.) They used to have their lunch at a bar on Gower Street, so, as an inside joke, "on Gower" became "Ungowa." It sounded just "foreign" enough that they got away with it, and it became an accepted part of the cinema Tarzan's rather limited vocabulary.
