What Are Compound Nouns?

A compound noun is a noun made up of two or more words. These words combine to form a new word with a single meaning.

• They can be written as one word: notebook, sunscreen.
• They can be written as two separate words: traffic light, post office.
• They can be hyphenated: sister-in-law, check-out.

The Main Rule: Stress on the First Word

For most common English compound nouns, the main stress is on the first word. This means you say the first part louder and with a higher pitch.

• Pense em FOOTball. We stress FOOT, e não ball.
• Another example is SUNglasses. The stress is on SUN.
• This rule applies because the first word often tells you the type or purpose of the noun.

Compound Nouns vs. Adjective + Noun Phrases

This is a very important distinction for B2 learners. The stress pattern helps you tell the difference between a compound noun and an adjective describing a noun.

• Compound Noun: BLACKbird (stress on BLACK). This refers to a specific type of bird.
• Adjective + Noun Phrase: a black BIRD (stress on BIRD). This refers to any bird that happens to be black.

Consider another example:

• Compound Noun: GREENhouse (stress on GREEN). This is a building for growing plants.
• Adjective + Noun Phrase: a green HOUSE (stress on HOUSE). This is a house that is painted green.

Why Is Correct Stress Important?

Using the correct stress pattern for compound nouns is crucial for several reasons:

• Clarity: It helps avoid misunderstandings, as seen with GREENhouse vs. green HOUSE.
• Natural Sound: Your pronunciation will sound more natural and fluent to native speakers.
• Easier Listening: It helps listeners understand your meaning more quickly and easily.

Exemplos

• My favourite sport is FOOTball.
• I need new SUNglasses for the beach.
• Look at that beautiful RAINbow after the storm!
• A BLACKbird sang a lovely song in the garden.
• She lives in a green HOUSE, not a GREENhouse where plants grow.
• I bought a HOTdog from the street vendor for lunch.
• Be careful, the hot DOG might be aggressive.

Erros comuns entre falantes de espanhol

Spanish speakers often place stress more evenly across words or sometimes on the last syllable. This can lead to a common mistake with English compound nouns: stressing the second word instead of the first.

• Incorreto: post OFFICE (This sounds like an office that is 'post', which doesn't make sense.)
• Correto: POST office (This is the place where you send mail.)
• Incorreto: tooth BRUSH (This sounds like a brush that is 'tooth', not the object for cleaning teeth.)
• Correto: TOOTHbrush (This is the correct pronunciation for the item you use to clean your teeth.)

This mistake can change the meaning of what you are saying or make your speech sound less natural to a native English speaker.
