Clarification Edit: for people who speak English natively and are learning a second language
Languages with phonetic writing in the modern day likely achieved that through a language standardization process that included spelling reforms.
Not Arabic. It is pronounced as it is written. Except a handful of words that have a different transcription to make them easily distinguishable.
As someone who is learning Arabic right now this is the vaaaaastest oversimplification I have ever seen on that subject in particular.
For starters, dialects
We only refer to MSA when talking about Arabic. Most Arab speakers consider dialects side languages to Classical Arabic. They have never had a transcription throughoutout history. People started writing in their dialects only recently with the arrival of SMS and the internet.
I get that as a new comer to Arabic you probably have come across learning materials for dialects like Egyptian and levantine. But in reality you won’t find uni courses for those dialects because academics don’t consider them to be proper languages with clear grammar and an established vocabulary.
Actually I chose to learn dialect first because literally everyone who knows anything about the language cautions that native speakers will swear up and down that you should learn MSA and then be completely incomprehensible to you because of how little anyone actually uses it in the Arab world.
I’ve been working with my teacher for a year and a half now and she agrees that MSA is basically pointless unless you intend to start consuming arabic language news or listening to arabic language political speeches.
BTW this is from a professional cultural expert who’s literal job is to prep government workers and businessfolks to be able to engage successfully with the Arabic world, something she’s been doing for 20 years now, so I’m pretty sure she knows what she’s talking about.
