Coined in 1810 by French-Danish geographer Conrad Malte-Brun (as "langues indo-germaniques") and popularized in German (as indogermanisch),[1][2] especially following J. Klapproth's 1823 Asia Polyglotta. At the time the term was coined, the Celtic languages were not yet considered Indo-European, and the Tocharian languages were not yet discovered; even after the inclusion of Celtic, Germanic remains the northwesternmost family (thanks to Icelandic).[1]
