Namely, most human language feature four skills, divided into productive skills and receptive skills.
- Productive skills: speaking and writing.
- Receptive skills: listening and reading.

Writing and reading would appear at a later time within the ancient cultures of Mesopotamia (who invented the cuneiform writing system) and ancient Egypt (who developed hieroglyphic and demotic writing systems).
