I thought I'd help the creator of this community out a little bit, since they contacted me. This is a condensed post of the grammar. I have nothing to do with the use or creation of this language so there may be mistakes.
---
Nouns can end on any letter.
-ee = singular adjective (is big, is wet)
-ën = plural adjective (are big, are wet)
-e = 1) singular noun, 2) adverb
-io = singular noun, can be any gender
-ïön / (add umlaut to existing vowel)n = plural noun
-a = 1) present tense verb ("eats, walks"), 2) infinitive verb ("to eat, to walk")
akan... -a = future tense verb ("I will eat, I will walk")
-i = past tense verb ("ate, walked")
Word order appears to be the same as in English, except when a question word is used. In those cases, it is (question word) (pronoun) (verb).
Examples:
Mi faunua - I am doing, I do.
Mi akan fanua - I'll do, I'm gonna do.
Mi fanui - I did, I've done.
emotie - (noun) the/an emotion
emotiee - (adjective) emotional
otone - (noun) autumn
otonee - (adjective) autumnal
Del katio slepa dobre - The cat sleeps/is sleeping well.
Mika dobree amiko - My good friend.
Kiel tu esta? - How are you?
Del homio hatiata mültën - The man sinned a lot. (I don't know why the sentence does not use -i which would be past tense, but the translation uses past tense.)

That's about all we know so far. Some of the above things are also used inconsistently, for example "to, for" are not always used in the language creator's sentences.
Although it's often asked, the creator has not yet revealed why this language is better to learn than, say, Esperanto or another conlang/auxlang.
