'Esperanto 1' -- subject(s): Esperanto, Grammar

Esperanto is a constructed language created to promote international communication. It has a simple grammar structure and draws vocabulary from various languages. It aims to be easy to learn and culturally neutral.

The revised form of Esperanto would involve updating its vocabulary and grammar to better reflect modern language usage. This could include incorporating loanwords from other languages, simplifying complex grammar rules, and improving the language's overall clarity and ease of use.

The best known artificial international language is Esperanto. It was created in the late 19th century with the goal of promoting peace and international understanding. Esperanto is designed to be relatively easy to learn and use, drawing from various European languages for vocabulary and grammar.
