hieroglyphic
Hieroglyphic (noun) means a system of writing, used by the ancient Egyptians and other early civilisations, that represents sounds through picture-like symbols.
Etymology
Coined in 1726 from French hiéroglyphique, from Latin hieroglyphicus, from Ancient Greek ἱερογλυφικός (hierogluphikós), from ἱερογλυφέω (hierogluphéō, "to represent hieroglyphically"), from ἱερός (hierós, "sacred, holy") and γλύφω (glúphō, "to carve, to engrave, to cut out"). By surface analysis, it splits into hiero- + glyphic.
