What are Modal Verbs?

Modal verbs are special verbs which behave very differently from normal verbs. Here are some important differences:

1. Modal verbs do not take “-s” in the third person.


  • He can  speak Chinese.
  • She should  be here by 9:00.

2. You use “not” to make modal verbs negative, even in Simple Present and Simple Past.


  • He should not be late.
  • They might not come to the party.

3. Many modal verbs cannot be used in the past tenses or the future tenses.


  • He will can go with us. Not Correct
  • She musted study very hard. Not Correct

Indiquen un estat i no tant una acció en procés i, per això, gairebé sempre s’utilitzen en la forma simple i no en la progressiva.

Están relacionats amb:
Els gustos, les emocions i el sentiments (like, love, prefer, want, dislike, hate, hope)
El pensament i l’opinió (appear, believe, consider, depend, doubt, forget, guess, imagine, know, mean, realise, remember, seem, suposse, think, understand)
La percepció i els sentits (feel, hear, see, smell, sound, taste)
La possessió (belong, have, owe, own, possess)
Els preus i les mesures (cost, weigh, measure)

Alguns indiquen les dues coses, estat i activitat, i poden utilitzar-se en la forma simple i en la progressiva.

Per exemple, think en Present Simple expressa opinió i en Present Continuous activitat mental en procés.
I think he knows the truth.
(crec/opino que ell sap la veritat)
She’s thinking about talking to her teacher.
(Està pensant a parlar amb el seu professor)

I el verb see en Present Continuous fa referència a una acció futura fixada per endavant.
He’s seeing his boss tomorrow.
(Demà veurà el seu cap)
