detención
/detenˈθjon/ · B1 · noun · f
apprehension
🚔🛑 detención = detain + -tion: the act of holding someone back
From Latin detinere, de- (away) + tenere (to hold), the same root as English detain and detention. Spanish -ción matches English -tion, so detención and detention are near twins. The -ción ending also tells you the noun is feminine: la detención.
