Fundamento de Esperanto: the 2,756 official roots

All 2,756 roots made official by Fundamento de Esperanto (1905), alphabetically, with their meaning in English and a link to each dictionary entry.

Fundamento roots are all roots found anywhere in Fundamento de Esperanto – in its Universala Vortaro, Ekzercaro, Gramatiko or preface (Antaŭparolo); this is how the Academy of Esperanto defines “fundamental”. A few appear only in the preface, for example kompetent- (“niaj plej kompetentaj amikoj”), and some were later confirmed in Official Additions.

Counts follow the officiality marks in Reta Vortaro (ReVo); the Academy of Esperanto keeps the official list in its Akademia Vortaro, and its own counts differ by a few roots. Words built from official roots are normal Esperanto even when they are not on any list: see Word building. Academy.
