Occidental is a traditional designation for anything belonging to the Occident, the West (Europe and the New World), as opposed to oriental (belonging to the Orient).
Occidental is an constructed language created by the Estonian naval officer and teacher Edgar de Wahl and published in 1922.
Occidental is a naturalistic planned language which is devised with great care to ensure that many of its derived word forms do reflect the similar forms common to a number of Western European languages. This was done through application of de Wahl's rule which is actually a small set of rules for converting verb infinitives into derived nouns and adjectives. The result is a language relatively easy to understand at first sight for individuals acquainted with several Western European languages. Coupled with a simplified grammar, this made Occidental moderately popular in Europe during the decade and a half before World War II, and it is believed that it was at its height the fourth most popular planned language, after Esperanto, Volapük and perhaps Ido, though its intentional emphasis on European forms coupled with a somewhat Eurocentric philosophy espoused by several of its leading lights hindered its spread elsewhere.
Occidental survived World War II, undergoing a name change to Interlingue, but gradually faded into insignificance following the appearance of a competing naturalistic project Interlingua in the early 1950s.Western Civilization
