Susjin

Susjulin is a mostly-isolating analytic language.

Setting
Susjulin is spoken by the populace of the Terran Federation in the year 2317. The Terran Federation is the federal government of the planet Earth. It evolved from the United Nations until it was the higher government of every nation on the planet. When the language was first created, it was instated as the lingua franca of politics. Soon it was adopted as the lingua franca of business, as well. As the language grew in usage, many languages instated laws which forbid its use in certain contexts so as to preserve their native languages. However, because the majority of the planet's governments had become capitalist states, the language of business became the most important, and soon all inhabitants of Earth were fluent. Within a hundred years, the native languages of the world's nations were extinct. The name of the language, Susjulin, is a perversion of its original, official name, Su Sjulin tauh Djuran du Raŧum, which translates into English as The United Language of Earth.

Phonology
The letter [h] is used to represent three phonemes, depending on its preceding vowel. If it follows /i/, /e/, or /ɛ/, it is pronounced as /ç/. If it follows /a/, it is pronounced as /ħ̞/. If it follows /u/, it is pronounced as /ʍ/.

The Susjulin alphabet, in addition to single-phoneme consonants, has double--phonemic graphemes corresponding to affricates and consonant clusters. Due to the lack of Latin graphemes, these are represented using Latin characters as consonant clusters, rather than single graphemes.

In addition to all of these consonants, all letters (including both single- and double-phonemic consonants) except [m], [n], and [h] can be palatalized or labialized, creating double- and triple-phonemic consonants. This palatalization and labializationis represented using the Latin alphabet with the letters [j] and [w] respectively.

There are only three written vowels, [i], [a], and [u], but they correspond to five different phonemes. [i] is normally pronounced /i/, but is pronounced /ɛ/ after a palatalized consonant, except at the end of a word when it is pronounced /e/. [u] is normally pronounced /u/, but is pronounced /o/ after a labialized consonant.

Two vowels can be legally placed proximally. If they are identical, this creates a geminated vowel. If they are not identical, this creates a diphthong. All Susjulin diphthongs are falling, including the opening diphthongs.
