Common Consonant Clusters in English

Speaking English can sometimes present difficulties. One contributing factor is the presence of consonant clusters, which are groups of two or more consonants next to each other in a word, like "bl" in “black.”

This article will take a closer look at consonant clusters, introduce you to the most common ones in English with example words, and provide some useful practice tips.

What are Consonant Clusters?

The English alphabet contains 21 consonant letters: B, C, D, F, G, H, J, K, L, M, N, P, Q, R, S, T, V, W, X, Y, Z.

The term "cluster" refers to a group of similar items gathered together.

Therefore, a consonant cluster is a sequence of consonant letters that appear and are spoken together. This group must contain at least two consonants, with no vowel letters (A, E, I, O, or U) separating them. Most consonant clusters are either two or three letters in length.

English features numerous consonant clusters:

• They can appear at the start of a word, making them "initial clusters" or "initial blends."
• They can also be found at the end of a word, known as "final consonant blends."
• Consonant clusters can even occur in the middle of words.

Pronouncing consonant clusters can be difficult for English learners, but because they are so common, it is crucial to learn them early.

The Most Common English Consonant Clusters

We will now review the most common English consonant clusters in alphabetical order.

Consonant Clusters that Start with B

1. B + L = BL

This consonant cluster typically appears at the beginning or towards the end of words.

Keep in mind that a consonant cluster should be pronounced as one smooth syllable. For BL, you would quickly combine the sounds "buh" and "ull"—it should sound similar to the word “bull.”

When producing the L sound, ensure your tongue touches your teeth.

Here are some example words containing the BL consonant cluster.

black	blue	noble
blur	blow	oblige
bland	able
block	dabble

2. B + R = BR

This cluster can be confused with BL, so pay attention to your pronunciation!

When pronouncing the R, your tongue should be curled and nearly touching the bottom of your mouth, not your teeth.

braid	broth	labrador
brew	brunt
brick	abrasive

Consonant Clusters that Start with C

3. C + H = CH

The CH cluster can be confusing because its pronunciation varies, depending on the word and its position.

Sometimes, CH sounds like "chuh." Your teeth should be close together, and a puff of air should pass between them. Your tongue will also flick to the roof of your mouth, just behind your top teeth.

However, CH can sometimes sound more like "kuh." It is not always easy to predict when this happens!

Pay close attention whenever you encounter a word with the CH consonant cluster.

change	chore	sandwich
check	chum	squelch
children	ostrich

4. C + L = CL

When pronouncing CL, your teeth will be close together and your tongue will touch near the back of your teeth. It will sound like "kuhl."

clear	cloud	acclaim
click	clown	manacle
clock	clutch	Cyclops

5. C + R = CR

Remember the R sound! Your tongue should be curled up and reaching toward the top of your mouth.

cream	crazy	micro
cry	crawl
croak	acrylic

Consonant Clusters that Start with D

6. D + R = DR

Fortunately, there aren't many consonant clusters beginning with D. DR is the most common one. It usually appears at the start or in the middle of words and sounds like "durr."

drive	drunk	adroit
drab	dream	cauldron
drone	dragon

Consonant Clusters that Start with F

7. F + L = FL

The FL cluster is usually found at the start of words.

Practice its sound by saying the word “full” rapidly.

fly	fling	aflame
flavor	flake	reflex
flower	flock

8. F + R = FR

When saying FR, your bottom lip should touch or be close to your top front teeth.

Practice saying the word “fur” quickly to get a feel for it.

fray	frog	saffron
freeze	frumpy
fridge	afraid

Consonant Clusters that Start with G

9. G + L = GL

The letter G can be tricky to pronounce. It can sound like "guh" or more like "juh."

The GL consonant cluster almost always uses the "guh" sound.

glass	glow	bugle
glen	glue
glide	angle

10. G + R = GR

Like the GL consonant cluster, GR also typically uses the "guh" sound. You will not find many English words ending with this cluster.

grass	grow	regret
green	gruel
grime	chagrin

Consonant Clusters that Start with P

11. P + L = PL

This consonant cluster is commonly found at the beginning of words.

When pronouncing PL, your lips will curl inwards, then release outwards with a puff of air. It's similar to a popping sound!

Practice the L sound by ensuring your tongue goes between your front teeth.

place	plow	splay
please	plum
plier	apple

12. P + R = PR

This can sound similar to PL, but remember, the R sound requires your tongue to curl up as you exhale.

pray	prod	caprese
present	prune
price	approve

Consonant Clusters that Start with S

13. S + C + R = SCR

This is a very common three-letter English consonant cluster. It is pronounced like "skur."

Start with a hissing sound between your front teeth for S, followed by a hard "kuh" sound for C and the curled tongue for R.

scrap	scroll	adscript
screech	scrunch
scribble	scry

14. S + H = SH

This one is easy to pronounce. It’s the same sound you use when you’re telling someone to be quiet.

Your upper and lower teeth should be touching, with your lips open and slightly protruding.

sharp	shore	cashier
shell	shudder
shine	mash

15. S + L = SL

Hiss for the S sound, and then push your tongue out to go between your front teeth for the L sound.

slang	slime	slurry
sled	slow	asleep

16. S + M = SM

You already know how to make the S sound! For the M sound, simply keep your lips closed and hum from your throat.

smart	smoke	cosmic
smell	smush
smirk	chasm

17. S + P = SP

This consonant cluster is common in all parts of a word: at the beginning, middle, or end.

After the hissing S sound, simply let air "pop" out from your lips to make the P sound.

A good word for practice is "super."

space	spoon	gasp
spear	spur	vesper
spiral	spy

18. S + T = ST

To pronounce ST, your mouth should almost look like you are smiling.

To make the T sound, your teeth should be close together (but not touching), and you'll use your tongue to push air between them. It's as if your tongue is gently tapping your teeth.

stand	stone	style
step	stove	first
sting	stuck	aster

19. S + T + R = STR

You can pronounce this as if you were adding an R sound after the ST consonant cluster—your tongue will roll back and touch the top of your mouth.

However, when some native speakers say STR quickly, it can sound like "sjurr" or even "schurr." The T sound becomes somewhat "soft."

We recommend practicing the first pronunciation method to achieve a clearer T sound.

straight	stripe	bistro
straw	stroke	pastry
streak	strudel

Consonant Clusters that Start with T

20. T + H + R = THR

This consonant cluster is a bit tricky because the English TH can be difficult to pronounce.

Ensure your tongue is between your teeth and slightly protruding, then blow air through them. Next, add the R sound by quickly pulling your tongue back inside and curling it upward.

thrall	throw	philanthropy
three	thrush
thrift	bathroom

21. T + R = TR

This one is easier than THR.

Simply make a regular T sound by using your tongue to "flick" air between your front teeth, and then make the R sound right after by curling your tongue up. Your teeth should be close together, but not touching.

try	trunk	betray
trick	trade
troll	tree

22. T + W = TW

After making a regular T sound, quickly pull your lips back as if you are about to smile, and you will almost automatically produce a "weh" sound.

twang	twilight	atwixt
tweet	two
twenty	intertwine

How to Learn and Practice Consonant Clusters

Watch English videos (with subtitles)

Watching English videos allows you to hear native speakers use consonant clusters frequently. This helps you learn how they should sound in various words.

It's best to watch videos with captions or subtitles so you can also see the consonant clusters as they are spoken.

There are many excellent English-teaching YouTube channels available. Here is one recommended channel for English pronunciation:

For additional learning support, consider other language learning platforms that use authentic videos—such as music videos, movie trailers, news, and inspiring talks—and transform them into personalized lessons.

Read English texts out loud

It is very important to practice pronouncing consonant clusters as much as possible. Whenever you read in English, we recommend reading aloud rather than silently.

You can start with graded learner books before progressing to more challenging texts. More difficult books are sure to contain longer English words and complex consonant clusters.

Have fun with tongue twisters

A tongue twister is a sentence full of words that are difficult to say quickly. Usually, all the words start with the same letter or a similar sound. Even native speakers find them challenging!

However, they can be a fun and effective way to practice consonant clusters (and impress your friends).

Here are some tongue twisters that feature consonant clusters:

She sells seashells by the seashore.

Stanley stands sadly on the steep stone steps.

Gleeful Glen wears green glasses.

Use your hands

Remember that a consonant cluster should be pronounced smoothly, as one syllable. To help ensure you are not separating it into multiple syllables, you can use your hands as a visual guide.

Hold both hands with palms facing up. Place one hand horizontally flat in front of you, then position the other vertically above it at a right angle.

As you say a consonant cluster, swipe the palm of your vertical hand across the horizontal hand, as if you are wiping dust off a table.

With consistent practice, you will become comfortable with consonant clusters. This will allow you to learn many everyday English words!
