Hi, I’m Olivier.

00:03

Welcome to Oxford Online English!

00:05

In this lesson, you can learn about sentence structure in English.

00:09

You’ll learn how to construct all kinds of sentences in English, from the simplest

00:15

possible sentences, to long, complex sentences which contain many different ideas.

00:23

To begin, a question:

00:25

What’s the simplest sentence you can make in English?

00:33

What does every sentence in English need?

00:37

Every sentence needs a verb.

00:40

The simplest sentence is an imperative, which means when you tell someone to do something.

00:47

For example:

00:49

Run!

00:50

Leave!

00:51

Work!

00:54

These are the simplest complete sentences you can make in English; they’re just one

00:58

word long!

01:00

Of course, most sentences are longer than this.

01:05

Most sentences that are longer than one word also need a noun before the verb.

01:10

This noun is the subject.

01:14

With a subject plus a verb, you can make simple sentences like:

01:20

He runs.

01:22

She left.

01:24

They’re working.

01:26

You can see that the verb can be in different forms: past or present, simple or continuous.

01:34

The verb form doesn’t change the structure of the sentence.

01:37

These are all the same: subject plus verb.

01:41

Of course, these sentences aren’t very interesting.

01:44

You can’t say much with short sentences like these.

01:48

Let’s add a little more information.

01:50

Take the sentence he runs.

01:53

What could you add after runs to make it longer?

01:58

You could add an adverb of place:

02:01

He runs around the park.

02:06

You could add an adverb of time:

02:09

He runs every morning.

02:13

You could add both:

02:15

He runs around the park every morning.

02:21

You could add an adverb of manner:

02:24

He runs slowly.

02:27

You can see that you have many choices, but your choices are also limited.

02:33

In this case, you can use different kinds of adverbs, but there are also things you

02:39

can’t use.

02:41

For example, you can’t use another verb after run, you can’t use an adjective, and

02:48

you can’t use a noun, or at least you can’t use a noun with this meaning of run.

02:53

This is an important point, so let’s look at it in more detail.

03:01

To build grammatically complete sentences in English, there’s one important question:

03:08

what needs to come next?

03:11

For example, you saw the sentence he runs.

03:15

That’s a complete sentence.

03:17

You can put a full stop after runs, and it’s correct.

03:21

It’s very basic, but it’s correct.

03:26

What about these:

03:28

She likes He wants

03:32

We go

03:35

These aren’t complete sentences.

03:37

Can you explain why not?

03:40

They aren’t complete, very simply, because they aren’t finished.
