Private Language is a term used by Ludwig Wittgenstein to denote by an oxymoron the sign system available for use by only one isolated user of the language.
For Wittgenstein and many other prominent authors who contributed to the development of semiotics, all languages are generally intersubjective; a system of completely private characters will not satisfy the name “language“.
Hans-Georg Gadamer, a representative of hermeneutics, emphasized this very position when he argued that “Whoever speaks a language, incomprehensible to anyone else, does not speak. To speak means to speak to someone” (1976, 65).
Only what is generally communicative for others deserves to be considered a language.
