Before we get started, we must keep in mind that
Auxiliary verbs:
• Are helper verbs
• Help the main verbs in a sentence to work
properly and to make sense
• Do NOT make sense on their own

These verbs can perform two
different functions
1) They can function as the main verb in
a sentence (they express meaning)
2) They can function as helper verbs
(auxiliary verbs)
![Page 6: What are Auxiliary Verbs? · Before we get started, we must keep in mind that Auxiliary verbs: •Are helper verbs •Help the main verbs in a sentence to work properly and to make](https://reader030.fdocuments.in/reader030/viewer/2022020206/5c8d4cb009d3f245088d149d/html5/thumbnails/6.jpg)
Let’s take the verb to be as an example.
In the sentences below the verb to be is functioning as a
main verb, therefore it is expressing meaning.
1) I am short. (expressing a state)
2) You are late. (expressing a state)
3) She is not scared of snakes (to be + not –
expressing negation)
4) Is he hungry? (asking a question)

Now have a look at the verb to be in the following
sentences and notice how its function changes.
Is it the main verb in the sentence?
Is it expressing meaning? What is it doing?
1. Jack is helping his father. (which one is the main
verb in this sentence? ‘Is’ or ‘helping’?)
What else can you notice? In which tense is this
sentence written?
2. They were running up the hill. (which one is the
main verb in this sentence? ‘Were’ or ‘running’?)
In which tense is this sentence written?
![Page 8: What are Auxiliary Verbs? · Before we get started, we must keep in mind that Auxiliary verbs: •Are helper verbs •Help the main verbs in a sentence to work properly and to make](https://reader030.fdocuments.in/reader030/viewer/2022020206/5c8d4cb009d3f245088d149d/html5/thumbnails/8.jpg)
So what can we conclude from the previous examples?
We can use the verb to be to form sentences in
different tenses e.g.
* present continuous:
- He is helping … (helping is the main verb)
* past tense
- They were running… (running is the main verb)
In both cases, the verb to be does not express meaning, or
make sense on its own, but is helping the main verb in the
sentence to make sense.

We can also use the verb to be as an auxiliary verb when we
use the passive voice.
We can use the verb to be before a verb in the
past participle:
- Letters are written neatly.
- The child was bitten by a mosquito.
- Fox hunting is considered illegal .
- The necklace was stolen.

ATTENTION: Let’s have a look at the verb to do in the
following sentences.
Can you identify the main verbs and the auxiliary verbs?
1) I do my homework every day. (expressing an
action)
2) My mum does the washing up. (expressing a
an action)
3) He doesn’t do ({to do + not} + do)– expressing
negation)
4) Did he do the dishes? (to do + do - asking a
question)

The last Primary Verb: to have
Look at the sentences below and identify the Main Verbs
and the Auxiliary Verbs.
• I have eaten all of my food.
• John has climbed Ben Nevis.
• Debbie had hidden all of Paul’s pencils.
So what can we notice about the auxiliary verb? When do we use it?
![Page 12: What are Auxiliary Verbs? · Before we get started, we must keep in mind that Auxiliary verbs: •Are helper verbs •Help the main verbs in a sentence to work properly and to make](https://reader030.fdocuments.in/reader030/viewer/2022020206/5c8d4cb009d3f245088d149d/html5/thumbnails/12.jpg)
ANSWER: We use the auxiliary verbs ‘have’, ‘has’ and ‘had’
in the present perfect or past perfect tense.
Therefore ‘have’, ‘has’ and ‘had’ are followed by the past
participle of the next verb.
• I have eaten all of my food. (eat – eaten)
• John has climbed Ben Nevis. (climb – climbed)
• Debbie had hidden all of Paul’s pencils. (hide - hidden)
Remember:
Present Perfect tense= Subject + has/have + past participle
Mary + has + written
Past Perfect Tense= Subject + had + past participle
Mary + had + written

Can you identify the verbs in these

Look at the sentences below.
Which are the MAIN VERBS?
• I _____ walking along the dusty road.
• Tomorrow I ___ go shopping.
• ____ dad do the dishes ?
• ____ he going to the party?
• She ____ watching a movie with her friend.
• _____ I take out the trash?
• ______ I speak to you for a minute?
• You _______ study hard if you want to pass your exam!

As we can see in the sentences below, the main verbs alone
do not make sense. Helper verbs (auxiliary verbs) are
needed to help form good sentences. Can you suggest
any?
• I _____ walking along the dusty road.
• Tomorrow I ___ go shopping.
• ____ dad do the dishes ?
• ____ he going to the party?
• She ____ watching a movie with her friend.
• _____ I take out the trash?
• ______ I speak to you for a minute?
• You _______ study hard if you want to pass your exam!
