devoto
/deˈboto/ · B2 · adj
devoted, devout
🙏 devoto = de- (completely) + voto (vow): fully vowed to something
Latin devotus means 'vowed away', from de- (fully) + vovere (to vow). Someone devoto has pledged themselves wholly to a faith, person, or cause. English 'devote' and 'vow' come from the same root.
