Expert Q&A

What is idioglossia, or "twin language"?

Idioglossia or "twin language" has been the focus of many research studies and has interested the public for years. It was once believed that twins could develop their own language unrecognizable by others. Today, research indicates that twin language is actually one twin modeling the immature or disordered speech pattern of their co-twin, which results in the incorrect use of speech sounds and grammar by both twins. If you've ever heard two children talking with delayed speech and language, you too may think they're talking in a foreign language.
