It said that the only obligatory authority for Esperanto speakers is the Fundamento de Esperanto (a collection of the early grammar, dictionary and sample text documents), which all speakers of the language are recommended to imitate for the sake of stability in the language.
However, the dictionary lacks any etymological references to the first use of a word and does not mention whether or not a word was personally introduced to the language by Zamenhof, or possibly even mentioned in his Fundamento de Esperanto.
