Modern Levantine Arabic preserves some Semitic features better than many ancient Semitic languages

Lebanese Arabic, my native dialect, is a dialect continuum of Classical Arabic spoken 1,400 years ago, probably more. It is a Levantine dialect of Arabic.

It uses the dual form better and more frequently than Biblical Hebrew and Aramaic, preserves more phonemic distinctions despite simplifying many sounds and is triconsonantal morphologically extremely similar, more conservative in some areas.

The thing is that Classical Arabic itself is known as the most conservative Semitic language, and Levantine Arabic just hasn't changed much, it's mostly skipped sounds + grammar simplification + lost cases.

Biblical Hebrew felt more connected to my native Lebanese dialect than Classical Arabic. I have not explored Aramaic as thoroughly as I have done with Hebrew, but as far as I can tell, Aramaic is closer to Classical Arabic than Levantine Arabic.
