The observation that all human languages are, by definition, constructed social agreements, but this theory specifically highlights deliberately invented languages like Esperanto, Klingon, or programming code. These are not organic evolutions but are built from scratch to fulfill a purpose—whether fostering global peace, enriching a fictional world, or giving unambiguous instructions to a machine. They prove that the core function of language (creating shared meaning) can be engineered, and their success or failure depends entirely on whether a community agrees to use and build upon the construction.
