ansiedad
/ansjeˈdad/ · B2 · noun · f
anxiety
Cognate of anxiety: -dad is Spanish for -ty, so ansie-dad = anxie-ty
Both words come from Latin anxietas, from angere, to squeeze or choke, the same root as anguish. Spanish -dad matches English -ty (ciudad = city, verdad = verity), so ansiedad maps straight onto anxiety. It's feminine: la ansiedad.
