Unit 4: Grammar: Modals

We might talk about modals but it could very well be something else. I could tell you so many grammar rules that you ought to know.

Modal auxiliary verbs

Modal auxiliary verbs are

auxiliary verbs that are used to show a(n):

 ability, certainty, possibility, probability or obligation (=necessity). 

Unlike most verbs, there is only one form of these verbs.

Must (expressing obligation)

Only 1 form: Must (e.g. no past tense, no perfect tense);

Use:

a)  When something is obliged (personally or from a source outside) or not allowed:

( My mother told me that ) I must wear sunscreen or I will get a sunburn. (personal obligation and an obligation from a source outside)

You must not park your bike in front of the school. (it is forbidden)

Must

b) to make deductions (= conclusions) when we are more or less certain about something:

You must be very tired, you worked so hard. (conclusion)

I must have left my notebook at home. (I do not know for sure)

Must vs Have to 

Must does not have a past or a perfect form so,

 If you need a past or a perfect form you use: 

Have to:  which can be used in all tenses:

Have to

has to  

had to

have had to

Must vs have to

Use: 

a)  An obligation made by someone else: 

You have to turn left here. 

You have to do your homework.

b) In the past:

I had to wear sunscreen last summer.

I had to park my bike at the back of the school.

must not vs do not have to

Must not -  something is not allowed:

You must not leave your bag near the staircase in the hall.

Do not have to - something is not necessary (hoeft niet):

You do not have to do your homework for tomorrow.
