Hello,

So I would like to tease out what you're looking at in this question because I saw this and it was a little confusing to me. From what you're asking, you don't see symbols as a form of writing but linguistics would disagree with it. A symbol can be a form of writing (see Egyptian Hieroglyphics) which combined with symbols can say something.

Second, pictograph is a legitimate form of communication. While I am not fully versed in Native American linguistics but most Native Americans before Columbus had a form of pictorial communication similar to hieroglyphics that was a form of writing. They don't need characters and they were very prosperous.

And to be meta, what is this but a series of symbols that equal writing? What does A mean? In English it's an article but it isn't the same in other languages, in French an 'a' can be 'of.' By itself, A doesn't mean anything but it can mean a lot of things, it's a symbol that combines with other symbols to create a system of communication.

So with this, could you please help us in what you're trying to ask for because the question is a little confusing.
