Lingvaon

Lingvaon is a constructed language project initiated by David G. J. Phillips. It is designed to be an auxiliary language, meaning it is intended for use as a universal second language. Phillips began developing Lingvaon in the early 1990s, drawing inspiration from a variety of natural languages. The project aims for simplicity and regularity in its grammar and vocabulary to facilitate learning.

The phonology of Lingvaon is based on sounds common to many languages, avoiding difficult or rare phonemes. Its grammar features a relatively straightforward structure, often employing analytical elements rather than extensive inflections. The vocabulary of Lingvaon is largely a priori, meaning it is not derived directly from existing languages, though some influences may be present. Lingvaon has a modest community of speakers and enthusiasts, and its development continues through online discussions and shared resources. The creator has published materials outlining the language's grammar and lexicon.
