Auxiliary languages are constructed languages designed to facilitate communication between speakers of different native languages. They aim to be easy to learn and use, promoting understanding and cooperation among diverse linguistic groups. Examples include Esperanto, Interlingua, and Ido. These languages often draw vocabulary and grammar from multiple languages, making them more accessible to a wider audience. While they are not intended to replace native languages, auxiliary languages serve as a bridge for international communication, cultural exchange, and collaboration in various fields, such as science and diplomacy.
