Explicação:

⇒⇒ Modal verbs >> são verbos ''diferentes'' que possuem características próprias. Não são conjugados, não recebem ''s'' na terceira pessoa do singular, não têm plural. São sempre escritos da mesma forma, independente do contexto, com exceção do ''have to'' que, na maioria das gramáticas não é considerado um ''modal verb'', e sim, um verbo comum.
