MODAL VERBS PROF.ª DANIELLE CACERES DA SILVA O que são “modal verbs”? São verbos diferentes dos outros pois possuem características próprias. São um tipo especial de verbos auxiliares que alteram ou completam o sentido do verbo principal. De um modo geral, estes verbos expressam ideias como capacidade, possibilidade, obrigação, permissão, proibição, dedução, suposição, pedido, vontade, desejo ou, ainda, indicam o tom da conversa (formal / informal). Os verbos modais (modal verbs) podem ser chamados também de modal auxiliaries ou apenas modals. • Não precisam de auxiliares (‘did’, ‘do’, ‘does’, etc.). • Não sofrem alterações nas terceiras pessoas do singular no presente, ou seja, eles nunca recebem “s”, “es”, “ies”. • Sempre após os modais o verbo deve vir no infinitivo sem o “to”. • não têm passado nem futuro (com exceção do can que tem passado e condicional).
