The Bare Bones

So, what is Elessic? What kind of language is it? What themes and features are important in its creation? I'll talk about this and more here.

Ideology

Elessic is meant to be the language of a race of Elves, and these Elves have a very different world-view than humans do. The most important things in the language are (in no particular order) Clarity, Simplicity, and Beauty.

Clarity

Elessic is meant to be inambiguous (though not to the degree of, say, Lojban). 

Verbs have obvious transitivity and only a few possible definitions, so the meaning is clear.

Words formed from other words use specific suffixes to indicate their relationship to the original. For example, the word "Bird" in the phrase "Bird House" would have a suffix to indicate that it is an adjective describing what uses the thing the adjective describes. A different suffix could be used to indicate that the house looks like a bird, if you wanted to.

As of right now, I am not allowing any homophones.

Simplicity

The rules of the language have no exceptions when it comes to things like pluralization and verbs function. A word is defined by its form, and to change its meaning one must change its form.

Verbs do not conjugate for person, only tense and plurality of the subject noun.

Beauty

The language must sound nice when spoken, and must look nice when written. If I don't like a word I've created when I begin to use it in the context of phrases, then I'll change it. If the language does not sound pretty or magical, then it is useless to me.

Structure

Elessic is a S-V-O language, primarily, but S-O-V is also acceptable, and is required in certain formal speech forms. The cases are as follows: Nominative, Accusative, Genitive, Dative 1, Dative 2. Cases are always expressed in some manner, though some have multiple ways they can be indicated.
Adjectives and Verbs reflect the plurality of their primary nouns.
Articles and Possessive-Pronouns reflect the plurality and case of their primary nouns.

In cases where a piece of the sentence (article, subject, verb, object) would be obvious, such a piece can be left off (this is mostly used to leave out articles).

Nouns are genderless.

Gender-specific nouns (such as "brother" and "mother") are formed by adding gendered suffixes to neuter bases.

Correlatives are formed by adding correlative prefixes to "noun category" bases. When used beside a noun, the prefix attaches directly to the noun, and the category base is left out. (This will all be explained later)

Double-negatives are improper and are to be avoided.

There's plenty more to say, but I'll get to that stuff when it comes up.
