medicamento
/medikaˈmento/ · B1 · noun · m
medicine
💊 medicamento = medicament: from Latin medicamentum, medicus (doctor) + -mentum
Latin medicari meant to heal, from medicus (doctor), and the suffix -mentum makes it a thing. So it is a healing thing. English kept the same word as medicament, and Spanish adds an -o: medica-mento.
