celebration
🎉🎂 celebr-ación = celebrate + -ation: -ción is Spanish for English -tion
From Latin celebratio, from celebrare, to honour or to fill with a crowd. The Spanish ending -ción matches English -tion, so celebración maps straight onto celebration. Like every -ción noun, it is feminine: la celebración.
