profundidad
/pɾofundiˈdad/ · B1 · noun · f
depth
🌊 profundo + -idad = profound + -ity: profundity, depth
From Latin profundus, pro (forward, down) + fundus (bottom), so literally far toward the bottom. Spanish -idad matches English -ity, so profundidad is profundity, the quality of being deep. Like most -idad nouns, it is feminine: la profundidad.
