Please don’t quote Arabic at me, Mosacked. I may have only 1 year of actual instruction, but I guarantee you that I know more about it than you just due to linguistic study (different from language instruction), and the people I referenced, like the Iraqi professor and my friends from Lebanon, Palestine, Saudi Arabia, etc. know a lot more about it than either of us. None of them dispute that “Allah” is the Arabic word for “God”. It is whether or not it is also a proper name that varies by community. For Muslims, it is. For Christians and Jews it isn’t. And, yes, it was the name of a pre-Islamic pagan deity, but so what?
In Amharic (another Semitic language, spoken by the Amhara people and nationally in Ethiopia), one of the words used for God is “Amlak”, which literally translates as “Idol”. Does that make the Amhara Orthodox Tewahido Christians idol-worshipers, too? Or is it a fact that languages evolve and Arab monotheists adopted the name of the supreme pagan deity to denote the Almighty God in Arabic as they adopted Judaism, Christianity, and (eventually) Islam? The second option of these two seems the far more likely of the two, but maybe you’re right, even though you apparently speak no Arabic at all and know nothing of Semitic languages or linguistics in general.
I’m going to side with every single Arab, Habeshi, and Maltese person I’ve ever met, as well as every Linguist, Semiticist, and Philologist I’ve ever met. They, after all, are the ones who taught me, and they speak these languages and come from these cultures, not you.
