It’s natural ro be afraid of learning the Arabic writing system, but keep in mind that it’s not a very complex one compared to, say, the Japanese. It’s just a different one.
It’s an Abjad system.
Pros:
- You have 28 letters. Each letter has one and only one sound. No combinations or funny business like say English.
- All words are basically derivations of simple roots. If you know the root for (write) then you know the words for writing, a writer, a book, a place to write in, a thing that’s written, etc.

Difficulties:
- vowels are implicit. Unless in special texts where they are indicated by marks on top of the letters, but this will be easier with time. Cn yu rd ths?
- letters are connected when written so a letter might look slightly different depending on its position in the word.
- spoken Arabic and written Arabic are vastly different. But you should learn both!
My suggestion is to not let the different writing system scare you. You can learn a conversational Arabic quite easily, as for classical written Arabic, take your time with it.
