as I was looking at the differences between Syriac and Aramaic. Interestingly, Syriac is in some instances the same thing.
It is a Semitic language with triliteral roots, but it has tense, which most Semitic languages do not, and a verb conjunctive, standard state, intensive state and extensive state. The script is Arabic related and was highly spoken until the eighth century when Arabic supplanted it.
So I find a language subgroup which I've never even heard of, it's in the Afro-Asiatic languages, called the Omotic languages, mostly in Ethiopia.
