It must be a Conlang after all, although I'm positive there are some influences from existing languages. I'm too uncreative to create everything all by my own, I'd suppose.And I've always used existing languages when creating a new one:)
As to my promised grammar, I thought about the neccessity of an evaluation. And considering it has approx. 20 cases and 8 tenses to express everything as it should, I thought it might not be that demanding to have one. Also, there are about 10-20 sounds not expressable with IPA or any script I am aware of(a sample, the language's name written "Cusanahusa" in latin script, is spoken with the "c"-sound being roughly the sound breathing in while saying "j", the two "s"-types are both similar to the sound of wind, however, with almost unrecognizable changed position of the tongue, which is rather important to identify some words. The "h" is roughly the sound when you speak "ɺ","χ" and "ɾ" together).
On the other hand side, I guess a grammar would be useful for a conlang. What do you think?
Cryptomnesia(taken from Wikipedia): Cryptomnesia occurs when a forgotten memory returns without its being recognized as such by the subject, who believes it is something new and original. It is a memory bias whereby a person may falsely recall generating a thought, an idea, a song, or a joke, not deliberately engaging in plagiarism but rather experiencing a memory as if it were a new inspiration.
