User:TheDarkEnigma2/List of constructed international auxiliary languages

Here is a list of constructed international auxiliary languages (constructed IALs, international auxlangs or worldlangs).

This list includes constructed languages (conlangs) that have been created to serve as international auxiliary languages, intended to be common second languages for people from different cultures, regions and linguistic groups to be able to communicate with each other.

Pretty much all IALs have never reached their intended goal of being global lingua francas, instead having a small dedicated community of speakers although often still having an international presence and sometimes a culture of their own.

This list does not include natural languages that have become, currently or historically, de facto world languages (such as English and French), constructed auxiliary languages that are only intended to be a common language for a specific region or language family (zonal auxiliary languages, such as Interslavic and Neolatino), and other constructed languages not intended to be real-world auxiliary languages (such as Lojban and Klingon).

Note that number of total speakers vary between sources and may not be accurate. Often, the criteria on who counts as a speaker can be different (i.e. number of fluent speakers vs. people who can read and understand the language even at an elementary level). The true number of speakers may also change over time.
