garantizar
/ɡaɾantiˈθaɾ/ · B1 · verb
to guarantee
🛡️✅ From Old French garantir, same root as warranty: the g- form of w-
garantizar = garant + -izar. A garante is a guarantor, someone who backs a promise. Frankish g- and Germanic w- are the same sound in two forms, as in guerra vs war and guardar vs ward. So garantizar is to give a warranty.
