GEOPHAGIST — [Noun] One who eats earth, such as clay, chalk, or soil. From the combining form geo- (from Greek gē, meaning "earth") and -phagist (from Greek -phagos, meaning "eating" or "eater"). Unlike pica, which denotes the broad disorder of craving non-food items, or coprophagist, which specifies a consumption of waste, the geophagist seeks a singular, elemental communion. It is the pregnant woman reaching for cool, damp clay; the soldier swallowing a pinch of dry, red dirt; the child tasting chalk-dust in a sunlit schoolyard—a visceral negotiation with the very fundament of being, a hunger that seeks to consume the ground it walks upon.
