Lettermology Request


I’ve been trying to understand the evolution from the ancestral glyphs (Egyptian / Phoenician / Proto-Sinaitic???) into an alphabetic system.

I’d like to read some of the foundational research that would support ideas such as the letter ‘A’ coming from a glyph for an ox and the sound that ‘A’ represents coming from the sound at the start of the old word for ox ('alp I think).

Would love recommendations on some quality sources for this.
