transformación
/tɾansfoɾmaˈθjon/ · B2 · noun · f
transformation
🦋 trans + forma + ción = across + shape + act of: the act of changing shape
Latin trans (across) + forma (shape) + Spanish -ción (the act of, like English -tion). Said aloud, it nearly matches English transformation: just swap -tion for -ción. A caterpillar changing into a butterfly is the classic example.
