asegurar
/aseɡuˈɾaɾ/ · A2 · verb
to claim, to maintain
🔒 a + seguro (secure, sure) + -ar = to make secure, to make sure
Built on seguro, from Latin securus, the same root as English secure, sure and assure. Asegurar sits right next to assure in sound and sense: you make a thing fast, make a person confident, or state a claim as sure.
