bastante
/basˈtante/ · A1 · adv
quite, rather, pretty, fairly
bastante = basta (enough!) + -nte: the amount that suffices
From the verb bastar, to be enough, the same root as the cry ¡Basta! (Enough!). The ending -nte works like English -ing or -ent, so bastante is literally 'sufficing'. From 'enough' it stretched to mean 'quite, fairly'.
