imaginación
/imaxinaˈθjon/ · B1 · noun · f
imagination
English -tion becomes Spanish -ción: imagination = imaginación
Both come from Latin imaginatio, from imago (image, likeness). Stress the last syllable, i-ma-gi-na-CIÓN, and say the g as a throaty h. Like nearly all -ción nouns, it is feminine: la imaginación.
