is an artificially-constructed auxiliary language(conlang) developed and published by Paris-based author Noubar Agopoff asa serious medium for easy and logical international communication. Mirad iscategorized by constructed language afficionados as philosophical because itsvocabulary is mapped letter-by-letter to a semantic ontology or thesaurus. Also,the wordstock of Unilingua is considered a priori, that is, there is no deliberateassociation with words or roots in existing natural languages. The vocabulary is"from scratch", yet based on internal lexical and semantic rules that help thelearner to construct and deconstruct derivations logically, mnemonically, andconsistently.
