This terminology was coined by Donald Knuth, who introduced it as part of his work on the theory of computation. The idea behind thyreolinguals is that they are "closed" languages, meaning that no two words have the same spelling or pronunciation. This means that any speaker of a language can understand the syntax and semantics
