Fragment from Jean-Pierre Gorin’s Poto and Cabengo.
(Gorin was a close collaborator of Jean-Luc Godard, once upon a time.)
“Idioglossia. A unique and private language, rarely but usually developed between twins. We would have to assume, twins who are severely neglected by adults. It is not “twin speech,” fairly common with very young twins — a hash of idioms and slurred common words. Idioglossia goes far beyond that; it is a kind of creole, a unique language, complete with grammar and syntax and neologisms.”
“Poto and CabengoÂ areÂ identical twinsÂ (real namesÂ Grace and Virginia Kennedy, respectively), who used a language unknown to other people until the age of about eight.Â They developed their own communication because they had little exposure to spoken language in their early years. Poto and Cabengo were the names they called each other.”
