What are auxiliary verbs?

[vc_separator border_width=”2″][dt_teaser]In English, auxiliary verbs are used to support another “normal” verb. However, these auxiliary verbs cannot appear alone in a sentence. That means they illustrate the statement behind a sentence, an example of this:

You must learn more.

You needn’t answer.[/dt_teaser]

How do you differentiate auxiliary verbs in English?

[vc_separator border_width=”2″]

For this purpose, a distinction is made between two groups of auxiliary verb. On the one hand the complete auxiliary verbs (be / do / have) and on the other hand the incomplete auxiliary verbs (can / must / may / will / need).

Consequently, the question arises:

 

What is the difference between complete and incomplete auxiliary verbs?

Basically, there is only one difference, which is that incomplete auxiliary verbs can only give 2 forms.

Furthermore, the full auxiliary verbs, as long as they are used as an auxiliary verb, serve to form other tenses for it. For an overview:

  • All progressive forms up to future 1 – and present – progressive

Incomplete auxiliary verbs in English:

[vc_separator border_width=”2″]

As already mentioned, incomplete auxiliary verbs in English can only be used as an auxiliary verb. The only exception is “need“. The name incomplete therefore comes to the fact that these auxiliary verbs can form either a present tense form or a present and imperfect form.

A simple example of an auxiliary verb English is as follows:

You must go to school.

 

Clarification of the word “must”:

Forms of the word “must”:

As already mentioned above, must belongs to the auxiliary verbs, which has only one present tense. So you need a replacement verb, such as have.

(have – had / has – had)

 

Note:

If you want to say “Need not” with the negation of must, it means “must not“. But if you don’t want to say, “Need not” you must use “Needn’t“.

If you want to say “Need not”, use needn’t.

For clarity, this article will help: must not need not (in German)

 

Function:

NECESSITY:

The function of must is based on a necessity, while, on the other hand, needn’t express a lack of necessity.

You must learn more.

You needn’t answer.

 

ACCEPTANCE / CONCLUSION:

Furthermore, must express an acceptance or a conclusion. For example:

She looks quite young. She must be under 18.

 

ADVICE:

Last but not the least, must express an urgent advice or a request. For example:

You must go to school.

About me

[vc_separator border_width=”2″]

Hey, I used to think that language learning was innate. Either you can speak English or not and it doesn’t matter how much you learn -“Anyway I don’t record good grades in English.” And that’s where English is so important.

 

After a while, I gave myself one last chance to learn English. Only this time I limited myself to the essential points.

For me, that meant verbs: formation – examples – signal words & usage

This method enabled me to learn English faster than ever before.

 

Since then I know that learning languages is not innate. And through that realization, my vision has become to offer other students the opportunity to learn English, just like I did back then. Now I ask you to help me by sharing this article with your friends!

Thank you very much!
