Etymology
Glossolalia is a borrowing of the γλωσσολαλία (glossolalía), which is a compound of the γλῶσσα (glossa) 'tongue, language' and λαλέω (laleō) 'to speak, talk, chat, prattle, make a sound'. The Greek expression (in various forms) appears in the New Testament in the books of Acts and First Corinthians. In Acts 2, the followers of Christ receive the Holy Spirit and speak in the languages of at least fifteen countries or ethnic groups.
