Ancient Egyptian hieroglyphs were a formal writing system used for over 3,500 years, combining ideographic, logographic, syllabic, and alphabetic elements with more than 1,000 distinct characters.  While many hieroglyphs represented entire words or concepts (ideograms), a subset of 24 symbols represented single consonant sounds, forming the Egyptian phonetic alphabet.  Vowels were generally not written, so the alphabet focused on consonant sounds, similar to early Semitic scripts.

Hieroglyphs could be written in multiple directions: left to right, right to left, top to bottom, or even in circular arrangements. The direction was determined by the orientation of the symbols, particularly those depicting living creatures, which faced the beginning of the line.  There was no punctuation, and symbols could serve as ideograms (whole words) or phonograms (sounds or parts of words), making the system complex to learn and interpret.

Hieroglyphic writing was primarily used by priests and scribes, with only about 1% of the population able to read it.  It appeared around 3200 BCE and evolved into cursive forms like hieratic and later demotic scripts for practical purposes. The script was considered sacred, often associated with the god Thoth, and was used extensively in temples, tombs, and religious texts.
