has no regulating body, as its vocabulary, grammar, and orthography are viewed as a product of ongoing social forces. In theory, Interlingua therefore evolves independent from any human regulator. Interlingua's vocabulary is
by dynamically applying certain general principles to an existing set of natural languages and their etymologies.
With the exception of Interlingua, all other auxiliary languages have been ''constructed'' by a person or small group. Constructed languages are by definition their inventors' regulations, so
, as known in natural languages, does not exist independent of the language itself.
