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).
