Medium: No, Lebanese is not a “dialect” of Arabic

The anachronism shown. The Phyla and Waves Models of Classification by Semiticists is not very scientific.

It would be an anachronism to assert that Italian is a dialect of Catalan, but safe to say that Italian comes from Latin. But when it comes to Lebanese (more generally NorthWestern Levantine), the “politically correct” Arabist-think-tank view is that is is derived from Arabic (Lebanese “dialect” of Arabic) to accommodate sensitivities — even linguists find arguments to violate the arrow of time to serve the interest of panArabism. In situations where there are similarities between a word used in Leb and Arabic, they insist it comes from Arabic not from a common root. (Most Lebanese are confused by diglossia as one is not supposed to write in the spoken language).
