1. Pertaining to characters or modes of writing used by the ancient Egyptians (or by transference, other peoples), consisting of figures of objects directly or figuratively representing words (picture-writing), or, in certain circumstances, syllables or letters: A hieroglyphic picture relates to a word or notion, especially one symbolizing something which it does not directly figure (like many of the Egyptian hieroglyphs), hence a figure, device, or sign, having some hidden meaning, a secret or enigmatical symbol, an emblem, or a hieroglyph.
2. Descriptive of something that contains or is inscribed with hieroglyphs: The personalized hieroglyphic writing or symbols on Carol's bracelet was absolutely lovely and could not be mixed up with the bracelets that her sister had.
