A hieroglyph is a type of ancient Egyptian writing that uses pictures and symbols to represent words or sounds. These writings were used by the ancient Egyptians for thousands of years, from around 3100 BCE until about 400 CE. Hieroglyphs are known for their intricate designs and detailed illustrations, which often depicted objects, animals, or people that represented specific ideas or sounds in the language. The word "hieroglyph" comes from the Greek words "hiero," meaning sacred, and "glypho," meaning to write. Together, they suggest a writing system that is considered sacred or important.
