Introduction[edit | edit source]

Arka and Kaldia started in 1991 in Japan.

Arka is an a priori conlang (naturalistic artlang to be exact) with more than 15,000 words and its own conworld, Kaldia.

It is strange that a conlang which exists in a conworld has words from English or Japanese, etc. It is, however, very difficult and tiresome to create whole vocabulary from scratch, so most of the conlangs have a posteriori or small a priori vocabulary. Some conlangs have large a priori vocabulary but most of them tend to be lack of etymology of words backed up by their conworld or conculture and to be an engelang like John Wilkins' Real Character. Therefore Arka is rare for the point that it has large a priori vocabulary (more than 15,000 words) based on its conworld (Kaldia) and conculture.

Arka is an artlang spoken in Kaldia, but it is spoken in the Earth, too. The founders are more than 30 people with different mother tongues like Japanese, Finnish, Esthonian, Ukrainian, French and German. The learners of Arka are from various countries like Japan, Korea, China, UK and USA. Currently the number of the learners reaches triple figures.
