Phoenicianism is a form of Lebanese nationalism adopted by a section of Lebanese people, at the time of the creation of Greater Lebanon. It constitutes identification of the Lebanese people with the ancient Phoenicians. Position Proponents claim that the land of Lebanon has been inhabited uninterruptedly since Phoenician times, and that the current population descends from the original population, with some admixture due to immigration over the centuries. They argue that Arabization merely represented a shift to the Arabic language as the vernacular of the Lebanese people, and that, according to them, no actual shift of ethnic identity, much less ancestral origins, occurred. In light of this "old controversy about identity", some Lebanese prefer to see Lebanon, Lebanese culture and themselves as part of "Mediterranean" and "Canaanite" civilization, in a concession to Lebanon's various layers of heritage, both indigenous, foreign non-Arab, and Arab. Some consider addressing all Lebanese as Arabs somewhat insensitive and prefer to call them Lebanese as a sign of respect of Lebanon's long non-Arabic past. Language Arabic The Arabic language is considered to exist in multiple forms: formal Arabic, commonly known as Modern Standard Arabic (a modern incarnation of Koranic or Classical Arabic), which is used in written documents and formal contexts; and dialectal variants, numbering some thirty vernacular speech forms, used in day-to-day contexts, and varying widely from country to country. The one spoken in Lebanon is called "Lebanese Arabic" or simply "Lebanese", and it is a type of Levantine Arabic, which, together with Mesopotamian Arabic, is classed by matter of convenience as a type of Northern Arabic. The point of controversy between Phoenicianists and their opponents lies in whether the differences between the Arabic varieties are sufficient to consider them separate languages. The former cite Prof. Wheeler Thackston of Harvard: "the languages the 'Arabs' grow up speaking at home, are as different from each other and from Arabic itself, as Latin is different from English." There is a lack of consensus on the distinction between lingual taxa such as languages and dialects. A neutral term in linguistics is "language variety" (a.k.a. "lect"), which can be anything from a language or a family of languages to a dialect or a continuum of dialects, and beyond. The most common, and most purely linguistic, criterion is that of mutual intelligibility: two varieties are said to be dialects of the same language if being a speaker of one variety
