Deimosian

Setting
Deimosian is spoken on Deimos, the outer moon of Mars. In the story, Deimosians were a zenophobic isolationist group living in a Martian colony. These isolationists emigrated to the uninhabited Deimos en masse in order to form an exclusive, insular culture. They constructed a language to discourage communication with others.

Keep in mind this is a story of a video game, so it's a bit of a stretch.

Some time later, this society evolves into a kingdom, with a wealth and beloved royal family. The language makes a transition from a method of isolation to a matter of significant pride. However, the kingdom proves to be quite troublesome to the rest of the solar system.

Phonotactics
Deimosian does not use a great variety of vowel sounds, and will avoid ending a word with any vowel other than "e". It is, however fond of consonant clusters, with as many as four sounds, as in the word Qatske. Also, I can't figure out how to add this to the template, but Deimosian uses a lateral or laminal click (I'll decide which later) which is denoted by the "q". Deimosian is rhythmic, but not necessarily sing-songy. Stresses usually fall on the first syllable with no secondary stresses, unless there is an affix with more than one syllable in which case a secondary stress will fall on the final syllable. For example, Iaojengai = Iao-jeng-ai.

Also note that this language has no post-alveolar affricates or fricitaves, but instead has alveolo-palatal sounds.

Basic Grammar
One of Deimosian's more unique features is it's lack of true adjectives. If you want to describe something in this language, you will usually have to resort to saying that something "is" something else, but only in a particular way. For example, to say that something tastes sweet, you would say, Om jerektsennarau, or "It is a flower in the way that it tastes." Jerektsen in this case meaning flower, and the suffix -narau, meaning in flavor.

Prepositions are also suffixes. The most frequently used of these is -ne, which means to, in, and at. For more specific relative locations such as inside of, towards, and on top of, there are more specific suffixes. For example, the sentence I lehne Deimosne, could mean "I'm going to Deimos" or "I'm moving around within Deimos." Most of the time, context would resolve this, but where more specificty is desired, you can say, I lehne Deimossrang" which means "I'm moving toward Deimos."

Deimosian also lacks a word for "and". In cases where "and" would usually be used, such as, "eggs, milk, and cheese", these items would simply be listed with tone indicating their connection. However, the lack of "and" creates a fatal confusion with prepositions. Without "and", certain distinctions we take for granted are totally lost. If I say, "The book is on a table, on a table", it's a safe bet I mean, "The book is on a table which is itself on another table". But for Deimosians who have no "and", the sentence could mean, "The book is on a table, and also on another table." And because of the fact that Deimosian avoids inflection like the plague, this kind of scenario would appear all the time.

In order to show the recursion of prepositions onto another, a sequence of recursive prepositions take a sequential vowel change. The second version of the sentence, in which the book is on two tables would read, "Keining behtrentsing, behtrentsing." In order to say what we really want to say, the second preposition, which is recurring onto the first, will change from "tsing", to "tseng". "Keining behtrentsing, behtrentseng".

Another example, "The language of the people of Deimos" would be "Ti, Jiahdireldve, Deimosdvo. 

The order of vowel sounds is always I, E, O, A, U. So if the final vowel sound is, U, it will become I, then E, and so on. If the final vowel sound is E, it becomes O, etc. This applies even if the prepositional affixes are different and have different vowels.

Example text
Om antreadtsene vereilnih.

That will cause a paradox.

''Qatskeleh sraine oalkne palqatskene. ''

Time travel requires the bending of space time.

I lehne deiqatskesrang.

I'm returning to the present.

Oma qatskejedrik kenr, prael ome kenetse.

That timeline doesn't exist anymore.
