How does letters were develop?

Letters were developed as part of a writing system to represent sounds and ideas visually. The earliest forms of writing, such as cuneiform and hieroglyphics, used symbols to convey meaning, but over time, alphabets emerged, simplifying communication by using a limited set of characters to represent individual sounds. This transition allowed for greater efficiency in writing and reading, facilitating the spread of language and literacy across cultures. The development of letters was influenced by the need for record-keeping, storytelling, and the exchange of information.
