Халбарзиниг нелбус, this conlang of mine has been frozen in its devolopement for ten years. The concept of Халбарзиниг нелбус is, instead having verbs conjugating between past and present as well as future tenses, Халбарзиниг нелбус uses verb-classes. In other words, there is a class of verbs for the past tense and, another class of verbs for the present tense. As for the future tense, there is yet another class of verbs for that.

Despite the fact that the concept for Халбарзиниг нелбус seems valid, in reality such a work and the ability to manage such verbs can be very difficult. Thus, the concept was then revised to having only a few conjugational verbs belonging to the three verb-classes stated and, the rest of the verbs actually functions akin to semi-nouns (Example in dialectal English: "I am a going").

The following is a sample of the Халбарзиниг нелбус:
Халбарзиниг нелбус едам хасэй бамихусайштах?
Нелбус хасэй барихусайм, одор шитво бамихуциграм.

Do you speak the Halbarzinig language?
