This glossary contains the 552 most frequent Esperanto words and morphemes (Groups 1 to 4 of the Baza Radikaro Oficiala, Aktoj de la Akademio II, 1968-1974). It also contains all words used in the Free Esperanto Course. It is estimated from word frequency studies that this corresponds to approximately 2000 words in other languages and covers 80 % of the words encountered.

The reader is assumed to be familiar with the rules of word formation in Esperanto; however, a few compound words which are likely to be difficult for the beginner (aligxi, denove, tagmangxo) are indicated separately.

Grammatical endings and affixes appear first, although most of them can be used as independent words (ulo: person; ebla: possible; etc.), as does the table of correlatives. The rest of the words appear alphabetically according to the root, so that "mon/o" appears before "mond/o", for example.

The letter following the slash indicates the grammatical nature of the root: /o for nominal, /a for adjectival, and /i for verbal. I have followed the grammatical categories in the Baza Radikaro Oficiala. A few roots and affixes are hybrid; in this case, both classes are indicated separately.

Words which appear in the Free Esperanto Course but are not among the 552 most frequent words are marked with an asterisk (*). A few correlatives also fall in this category.
