Idioglossia

Idioglossia does basically mean the same thing as Cryptophasia, however, it is not solely related to twins, but also sometimes used in connection with siblings, whereas Cryptophasia is only used when referred to twins. Idioglossia refers to an "idiosyncratic language" [INT 4], that is spoken by a limited group of people; mostly an autonomous language of young children.

Idioglossia, though, can also describe "a pathological condition characterized by speech, which is so distorted as to be unintelligible" [INT 2].

Consequently, Idioglossia has two meanings:

  • 1. A private form of speech invented by children.
  • 2. A pathological condition.

The first time the term Idioglossia was used, was in "1891 by Hale White and Golding Bird to describe a defective condition of speech in two brothers aged ten-and-a-half and nine years, which gave the impression of an individual language." (Wolf 171).

Since Idioglossia has the same outline in its origin and description of language abnormality as Cryptophasia, and only differs in so far that a wider number of people are covered by this term, I won't describe it any further. The terminological expansion of Idioglossia also being a pathological condition, is not relevant to the topic of Cryptophasia and will also not further described here. Everything else can be found in the explanation of Cryptophasia.
