In this lesson, I'll go over the pronunciation

of the 'th' sounds.

I'll remind you how to make the sounds

because actually there are two sounds

made by the letters 'th'

and I'll give you some guidelines

to help you to decide when to use each sound.

And more importantly,

we'll practise using these sounds in sentences

because that's when it gets tricky.

Before we get started,

I want to say a huge welcome to my newest subscribers

I'm looking forward to taking you on an

English language journey.

If you haven't subscribed to my channel yet,

then you can do it just by

Okay so the 'th' sounds are really common,

really common in English,

though, not many other languages use these sounds.

So if you're having trouble pronouncing the 'th' sounds,

then don't feel bad about it, you're definitely not alone.

But the good news is you can improve this sound

and you can start to feel more natural as you're using it

but you have to commit!

Improving your pronunciation is like going to the gym.

The first time, you're gonna suck at it.

But each time that you go back

and you work those muscles a little bit more,

the easier it will get

and the better you'll feel about yourself, right?

So remember, that the tongue is also a muscle

and you need to strengthen it, you need to workout.

So let's review the position of the tongue.

Open your mouth and push your tongue through,

just a little,

not like this,

like this.

Put your finger there if you're unsure about

where to stop your tongue.

Notice that the tongue is not completely relaxed,

there's a little tension.

If you rub the bottom of your teeth with your tongue,

can you feel the tension in your tongue?

This is the same amount of tension that you need to

hold the 'th' position.

The tongue is not completely relaxed, it's lifted

and running through the middle of your mouth.

If your tongue is too high in the mouth,

up behind your teeth,

you'll make that /t/ or /d/ sound.

And if your tongue is not coming through your teeth,

if you keep it inside, you'll make a /s/ or a /z/ sound.

So you really must pay attention to the tip

of your tongue,

it must come through between your teeth.

Now as I mentioned, there are two 'th' sounds,

a voiced sound and an unvoiced sound.

Now both of these sounds use exactly

the same mouth position.

It's just that the sound comes from a different place.

Voiced consonant sounds

are made using the vocal cords.

So once you've got your teeth and your mouth in

position and you make a sound here,

you should feel a buzzing.

It might even tickle your tongue a little.

Unvoiced consonant sounds are made by air

pushing through your mouth.

So it's the air that creates the sound.

So keep your tongue and your mouth

in the same position,

make sure you've got some air in your lungs

and push the air through.

So this is the unvoiced 'th' sound.

So when should you use the voiced

or the unvoiced sound?

That's a great question

because both sounds are represented

by the same letters.

And I wish I had a simple answer for you,

I know that you like it when I have a simple explanation

of why this rule is like that and when you should use it

but unfortunately in this situation,

there are lots of exceptions.

But there are some guidelines

that I'm going to share with you,

guides that will help you to make a decision

and help you to use the correct 'th' sound.

Remember they're guides, not rules

but let's focus on the unvoiced sound first,

made with air.

So a 'th' at the beginning of content words

is usually an unvoiced 'th' sound.

So content words are words that provide

the meaning in a sentence.

There are nouns, verbs, adjectives, adverbs.

Words like 'think' and 'thought' and 'thirsty'

and 'thankful' and 'theory'.

So the 'th' at the start of content words

is usually unvoiced.

Now if there is a 'th' in the middle of a word,

before a consonant,

it's usually unvoiced.

'bathtub'

'faithful'

'worthless'

And a 'th' at the end of a word is usually unvoiced.

'month'

'strength'

'warmth'

'teeth'

'fifth'

There are some exceptions though.

And I'm going to talk about those in just a minute.

Now the voiced 'th' sound

made using your vocal cords.

So if there's a 'th' at the beginning of a structure word,

they're usually voiced. So structure words,

sometimes called function words,

are different to content words

because they don't have a lot of meaning in

English sentences. They're grammatical words.

They don't tell us a lot of information but they're

important to the structure of English sentences.

So structure words are words like 'this', 'that', 'those',

'these', 'the', 'there', 'then' or 'than'

So all of these words, I mean, some of these words are

very, very, common English words, right?

They're very, very common.

So learning to pronounce the different 'th' sounds

is really important

if you want to sound natural when you speak English.

There is a noticeable difference.

Now a 'th' in the middle of the word, when it's between

two vowel sounds is usually this voiced sound.

'bother'

'worthy'

'mother'

Now I said the 'th' is usually unvoiced

at the end of words but except

if the word ends ends in '-the'

like 'bathe', 'breathe' and 'loathe'.

So these are pretty good guides

but there are always exceptions, aren't there?

English!

There are exceptions like 'smooth'

and 'clothes'

and 'frothy'.

All of these words are breaking the rules

and there are more!

Actually if you can think of any more,

please add them to the comments

so that we can talk about

some of the exceptions in the comments.

But anyway,

now that you've got through most of these guidelines,

it's time to practise.

So I want you to repeat after me.

Throw those things.

Throw those things to Theo.

There are three of them.

There are three of them over there.

Ready for this one?

At three thirty on Thursday,

a thousand of those thrilling thinkers will gather.

At three thirty on Thursday,

a thousand of those thrilling thinkers will gather.

I love tongue twisters!

Can you think of your own 'th' tongue twister?

I think I thought I..

If you can think of one, put it in the comments

so that we can all practise together.

Put your 'th' tongue twisters

right down in the comments and let's practise!

What a workout!

Well done to you!

I mean your tongue might feel

a little exhausted after that

so you can take a break now.

But make sure that you come back to this lesson

tomorrow or the next day and practise again.

It's just like doing sit-ups right? Each time you do it,

it will get a little bit easier.

Well that's it for this lesson!

I really hope that you enjoyed it.
