As the stock of human knowledge has increased, this evolution has imposed branching into disciplines which use special terminology understood “correctly” only by experts. This has raised barriers that impede communication since interpretations of terms and knowledge can vary significantly, especially in a multidisciplinary context. Misinformation is exacerbated by vague definitions including synonyms, homonyms and acronyms. This paper aspires to pinpoint the necessity of eliminating homonyms and synonyms. It attempts to illustrate the impact of misinforming that results from lexical disorder within the context of cross-disciplinary transfer of knowledge, standards setting and global business communication. The examples of homonyms and synonyms that have been observed to cause misinterpretations are presented. The genuine need for introducing a multidisciplinary transparent lexicon is advocated. A definition of a term "definition" is presented as a reference that highlights the inadequacy of homonyms and synonyms. Exemplary definitions are provided as models of transparent lexical terms. It is recommended that a hierarchy of terminology be adopted, giving the most fundamental disciplines the priority, and making sure that the other disciplines conform. A properly defined term is an information probability intensifier.
