Eugène Lanti was a pseudonym of Eugène Aristide Alfred Adam, an Esperantist, socialist and writer. He was a founder of Sennacieca Asocio Tutmonda, and a longtime editor of the internationalist socialist magazine Sennaciulo. Lanti was a critic of Stalinism and the theoretician of a new doctrine, anationalism, which aimed to eliminate the very concept of the nation as a guiding idea of social organisation.
Gender asymmetry is an aspect of the constructed international auxiliary language Esperanto which has been challenged by numerous proposals seeking to regularize both grammatical and lexical gender.
The original word base of Esperanto contained around 900 root words and was defined in Unua Libro, published by L. L. Zamenhof in 1887. In 1894, Zamenhof published the first Esperanto dictionary, Universala vortaro, which was written in five languages and supplied a larger set of root words, adding 1740 new words.
An Esperantido is a constructed language derived from Esperanto. Esperantido originally referred to the language which is now known as Ido. The word Esperantido contains the affix (-ido), which means a "child, young or offspring". Hence, Esperantido literally means an 'offspring or descendant of Esperanto'.

Like natural languages, the constructed language Esperanto contains profane words and indecent vocabulary. Some of this was formulated out of the established core vocabulary, or by giving specific profane or indecent senses to regularly formed Esperanto words. Other instances represent informal neologisms that remain technically outside the defined vocabulary of the language, but have become established by usage.

The Esperantist of the Year is an honorary designation bestowed each year by the editors of the Esperanto-language monthly La Ondo de Esperanto. The award recipient is selected by an international jury led by Halina Gorecka, the Russian publisher of the magazine.
Esperanto derivation is for the most part regular and predictable: One can normally understand new words that are built upon known roots, and can create new words on the fly while speaking. However, there is an infix -um- that has no inherent meaning, but derives words that cannot be readily derived with dedicated affixes. Such derivations must be memorized individually, though because the root already exists, they may be more easily learned than a completely new word. Because of its irregularity and unpredictability, over-use of the infix -um- is discouraged. Over time substitutes have been developed for some of the original -um- words and new ones have been coined. Regular derivations may in some cases substitute for a word in -um-; in other cases they may be similar but not exact replacements; and in still others, a substitutable word may be considered jargon.

Reta Vortaro is a general-purpose multilingual Esperanto dictionary for the Internet. Each of the dictionary's headwords is defined in Esperanto, along with additional information, such as example sentences, to help distinguish the subtle shades of meaning that each particular word form may have.
Komputeko is an online project of the non-profit youth organization E@I (“Education@Internet”) with the goal of bringing together parallel computer terminology from various dictionaries in order to facilitate access to and comparison between different translations and thus promote exact use of language and counteract the usage of linguistic borrowings from American English. Komputeko is short for the Esperanto noun phrase "Prikomputila terminokolekto", meaning "collection of computer terms". The dictionary is written in five languages, and there are plans to expand it into other languages. A preliminary version with a few other languages already exists.
