Zwani

Zwani (in Latin script) Зўани (in Cyrillic script) ზჳანი (in Georgian script) (/zwa.ni/) is a language spoken by humans on Jupiter's moon, Europa, in the Kingdom of Europa, where it is the sole official language of it's entire population of 32 million people. 

General information
Zwani is a synthetic nominative-accusative head-initial language. It is considered a language isolate. Word order is usually (S)VO, but the subject is optional as Zwani is a pro-drop language. Pronouns, when used, are usually for emphasis or with the imperative form of a verb. Verbs conjugate for numbers, tense, person, and mood. Nouns decline for number and case. Pronouns decline for gender, number, case, and person.

History
In the year 2050 a plan to terraform Earth's moon, Mars, mars' moons, and the four largest moons of Jupiter is proposted in order to avoid over-population on Earth. It is approved and accepted by almost everyone, and by 2100, all 8 celestial bodies are inhabitable by humans. By the year 3000, all of the Mars and all of the moons are fully inhabited and have thriving societies. Zwani is spoken on Jupiter's smallest inhabited moon, Europa (Zwani: Ózłopa). At first, three main languages were spoken on Europa: English, Turkish, and Russian, with smaller diasporas of languages such as Polish, Armenian, German, and Georgian. By 2500, the speakers of Earth-languages are starting to speak multiple creoles in order to communicate, and by 3000, a single creole language is formed, which eventually evolves into an entirely new language as the amount of Europians increase. By the year 4000, Zwani is spoken natively by the entire population of the Kingdom of Europa, about 32 million people.

Alphabets
The alphabet used is dependant on where in the Kingdom of Europa one is. The Latin script is the most widely used, but if one is in an area with a large amount of ethnic Russians or Georgians, it would be expected to see the Cyrillic script or Georgian script respectively. Most, if not all, Europians can read each script to some degree. While all official documents are required by law to be written in the Latin alphabet, there is no law against using the Cyrillic or Georgian alphabets. In some jurisdictions the Cyrillic and Georgian alphabets are used by large amounts of people. All three scripts are regulated by the College of Zwani.

The ethnic Armenians historically used the Armenian script, but over time they adapted to using the Georgian script. While neither official, nor regulated, a few small, isolated villages still use the Armenian script to write Zwani.

If two vowels are written in a row, they are always pronounced as two vowels seperated by a glottal stop. Because of this, the glottal stop (, ъ, or  ჸ'),  despite being an official letter of each script, is usually omitted in writing because it only appears between two vowels in a row. All official documents are written with the glottal stop.

Phonotactics
(C)(C)(C)V(C)(C)(C)

Any single consonant may occur initially, and any consonant other than /j/ may end a syllable. The onset's actual structure is (C)(C)(S) where (S) is a semivowel. The only 3-consonant consonant clusters allowed are str, spr, and skr.

Number prefixes

 * the glottal stop is only used when the noun begins with a vowel
 * if you're speaking about two of something, the dual number must  be used. this is for ease of speaking
 * the dual and plural prefixes force the noun or pronoun to take the plural conjugation of the verb if the noun or pronoun is the subject

Case suffixes

 * nouns can never end in /j/, so the accusative case suffix is always -ja
 * the genetive case ending is only ever -is if the noun ends in an affricate or a fricative other than /f/ or /v/
