If you’ve ever tried to describe someone in English, tell a doctor what hurts, or work out why someone told you to break a leg right before an exam, you’ll know that body vocabulary in English comes up all the time — often without us even noticing. And no, knowing head, arm and leg simply won’t cut it. 🙂

In this guide you’ll find the vocabulary of the human body organised by area (with its pronunciation), plus the bits almost nobody teaches you: the most useful idioms with body parts, handy verbs and collocations, how to talk about aches and pains, and how to put all of this to work in your Cambridge exams. There are exercises with answers and an FAQ at the end. Let’s get started!

Parts of the body in English: the head and the face

Let’s start at the top. The head and the face are home to a huge amount of everyday vocabulary that you’ll need to describe people and to get by day to day.

🇬🇧 EnglishPronunciation🇪🇸 Spanish
head/hed/cabeza
face/feɪs/cara
hair/heə(r)/pelo
forehead/ˈfɔːhed/frente
eye/aɪ/ojo
eyebrow/ˈaɪbraʊ/ceja
eyelash/ˈaɪlæʃ/pestaña
ear/ɪə(r)/oreja / oído
nose/nəʊz/nariz
cheek/tʃiːk/mejilla
mouth/maʊθ/boca
lip/lɪp/labio
tooth (pl. teeth)/tuːθ/ (/tiːθ/)diente (dientes)
tongue/tʌŋ/lengua
chin/tʃɪn/barbilla
jaw/dʒɔː/mandíbula

Watch out for a classic trap: hair is uncountable when we talk about hair in general (She has long hair), so it’s never «hairs». And remember that tooth has an irregular plural, teeth — if you enjoy these odd plurals, have a look at our post on irregular plurals in English.

The torso in English

The torso covers everything from the neck down to the waist. This vocabulary is really handy for talking about sport, health and clothes.

🇬🇧 EnglishPronunciation🇪🇸 Spanish
neck/nek/cuello
throat/θrəʊt/garganta
shoulder/ˈʃəʊldə(r)/hombro
chest/tʃest/pecho
back/bæk/espalda
stomach/ˈstʌmək/estómago
belly/ˈbeli/tripa, barriga
waist/weɪst/cintura
hip/hɪp/cadera

Mind another common mix-up: waist (the part of your body) sounds exactly like waste (to use something badly), but the two have nothing to do with each other. 🙂

Arms and hands in English (fingers included)

Here’s some vocabulary you’ll use constantly — especially the names of the fingers, which hardly ever get taught and yet always seem to come in handy.

🇬🇧 EnglishPronunciation🇪🇸 Spanish
arm/ɑːm/brazo
elbow/ˈelbəʊ/codo
wrist/rɪst/muñeca
hand/hænd/mano
palm/pɑːm/palma
finger/ˈfɪŋɡə(r)/dedo (de la mano)
thumb/θʌm/pulgar
nail/neɪl/uña
knuckle/ˈnʌkl/nudillo

In English, the fingers each have their own name — we don’t number them the way you might in other languages:

  • thumb – pulgar
  • index finger (or forefinger) – índice
  • middle finger – corazón
  • ring finger – anular
  • little finger (or pinky) – meñique

Notice that thumb has a silent b: it’s pronounced /θʌm/, with no b at the end. It’s one of those spellings English throws in just to keep you on your toes.

Legs and feet in English

🇬🇧 EnglishPronunciation🇪🇸 Spanish
leg/leɡ/pierna
thigh/θaɪ/muslo
knee/niː/rodilla
calf (pl. calves)/kɑːf/ (/kɑːvz/)pantorrilla
ankle/ˈæŋkl/tobillo
foot (pl. feet)/fʊt/ (/fiːt/)pie (pies)
heel/hiːl/talón
toe/təʊ/dedo del pie

Two more with silent letters: knee (/niː/, the k is silent) and calf (/kɑːf/, where the l disappears). And yes, foot is another irregular plural: feet.

The internal organs of the human body in English

This vocabulary crops up more often than you’d think: in reading texts, in documentaries, and the moment you start talking about health.

🇬🇧 EnglishPronunciation🇪🇸 Spanish
brain/breɪn/cerebro
heart/hɑːt/corazón
lung/lʌŋ/pulmón
liver/ˈlɪvə(r)/hígado
kidney/ˈkɪdni/riñón
stomach/ˈstʌmək/estómago
bone/bəʊn/hueso
muscle/ˈmʌsl/músculo
skin/skɪn/piel
blood/blʌd/sangre

Keep an eye on muscle /ˈmʌsl/: the c is silent. And blood is pronounced /blʌd/, to rhyme with mud, not food.

How to pronounce them: tips to avoid slip-ups

Body vocabulary is full of silent letters and sounds that don’t exist in Spanish. Hold on to these:

  • Silent letters: thumb, knee, muscle, calf, wrist. Don’t pronounce them.
  • The /θ/ sound (tongue between your teeth) turns up in thigh, throat, mouth, tooth and thumb. It’s not a z or a t.
  • Irregular plurals: tooth → teeth, foot → feet. Don’t just add an -s.

Useful expressions and phrases with body parts

And now for the good stuff — the bit that makes the difference between sounding like a beginner and sounding natural. English is packed with expressions built around body parts, and getting to grips with them will earn you a lot of credit, especially in your Cambridge exams.

Idioms with body parts

These idioms are among the most common ones. Learn them with their meaning and an example:

Verbs and collocations with body parts

Plenty of body parts double up as verbs, too. They’re a great resource for more advanced writing:

  • to face (something) – to confront it: We must face the problem.
  • to shoulder (responsibility) – to take it on: She shouldered the blame.
  • to head (a team / somewhere) – to lead / to go towards: He heads the department.
  • to hand (something to someone) – to pass it over: Please hand me the report.
  • to eye (something) – to look at it closely or longingly: The kids eyed the cake.
  • to elbow (your way) – to push through: He elbowed his way through the crowd.
  • to foot (the bill) – to pay for it: My company footed the bill.

Talking about aches and health (at the doctor’s)

If you travel or live in an English-speaking country, sooner or later you’ll need to explain what’s wrong. Notice how we build aches with -ache:

  • I have a headache. – Me duele la cabeza.
  • I have a stomachache / toothache / backache. – Me duele el estómago / una muela / la espalda.
  • I have a sore throat. – Me duele la garganta.
  • My leg hurts. / My arm is sore. – Me duele la pierna / el brazo.
  • I feel dizzy. – Estoy mareado/a.

Body vocabulary in the Cambridge exams

As a Cambridge exam preparer, I can promise you this vocabulary turns up more than you’d expect. Let’s look at where you’ll meet it and how to make the most of it.

Describing people in the Speaking

In the Speaking — especially when you have to describe a photo — it’s very common to describe what people look like: He has short dark hair and brown eyes, She’s got broad shoulders. Pairing this vocabulary with a few personality adjectives will let you describe someone fully and naturally.

Word formation in the Use of English

In the Use of English (Part 3 at B2 and C1), many body words form word families that regularly show up in word-formation tasks:

  • muscle → muscular
  • health → healthy / unhealthy
  • strength → strengthen
  • blood → bloody / bleed

Tips for learning body vocabulary

  • Label your own body. Point to each part and say the word out loud. Movement helps it stick.
  • Learn in chunks, not endless lists. Study by area (face, hand, leg…) rather than 60 words in one go.
  • Make idioms a priority. Learn two or three expressions a week and use them in your own sentences.
  • Mind your pronunciation from the start. Pay attention to those silent letters so you don’t fossilise mistakes.

Frequently asked questions about body vocabulary in English

What’s the difference between finger and toe?

It’s simple: a finger is on your hand and a toe is on your foot. English always keeps the two apart.

Is hair countable or uncountable?

When we talk about hair in general it’s uncountable (She has curly hair). We only use hairs for individual strands (There’s a hair in my soup).

Why do tooth and foot change so much in the plural?

They’re irregular plurals (teeth, feet) that don’t follow the usual -s rule, so you simply have to learn them. You’ll find more of them in our post on irregular plurals in English.

Are body idioms worth learning for the exams?

Absolutely. A well-placed idiom lifts your Speaking and your Writing, and shows the kind of command of English that examiners look for at B2, C1 and C2.

Conclusion

You now have body vocabulary in English in far more depth than a plain list: organised by area, with pronunciation, idioms, verbs, health phrases and a direct line to your Cambridge exams. Now it’s over to you — pick a handful of words and expressions and start using them today.
