English pronunciation is not only about saying sounds clearly—it’s also about stressing the right syllables. In compound words, the stress placement can change the meaning, and knowing the rules will make your speech more natural. Let’s look at how stress works in different kinds of compounds.
What are Compound Words?
A compound word is formed when two or more words are joined together to create a new word with a specific meaning.
There are three main types:
- Compound nouns: e.g., toothbrush, haircut
- Compound adjectives: e.g., part-time, open-minded
- Compound verbs: e.g., to babysit, to proofread
Stress in Compound Nouns
Compound nouns are nouns made by joining two words together to create a new word with its own meaning.
Examples:
- toothbrush (tooth + brush) → a brush for cleaning teeth
- bookstore (book + store) → a store that sells books
- haircut (hair + cut) → the cutting of hair
They can be:
🔹 One word: football, newspaper
🔹 Hyphenated: mother-in-law, check-in
🔹 Two separate words: ice cream, bus stop
Main Stress on the First Part
1️⃣ Noun + Noun
Examples:
- ˈGreenhouse (a building for growing plants)
- ˈToothbrush (a brush for teeth)
- ˈBedroom (a room for sleeping)
- ˈNotebook (a book for notes)
- ˈFootball (a ball or game)
2️⃣ Noun + Verb-ing Form (-ing)
Examples:
- ˈSightseeing (the activity of seeing sights)

- ˈTimekeeping (measuring time)
3️⃣ Verb-ing Form (-ing) + Noun

4️⃣ Verb + Noun
Examples:
- ˈPickpocket (a thief who picks pockets)
- ˈPlayground (a ground to play on)
- ˈBreakfast (meal when you break the fast)
- ˈScarecrow (crow-scarer)
Main Stress on the Second Part
This pattern is less common but important.
1️⃣ Adjective + Noun
Examples:
- bad ˈtemper (a state of anger)
- full ˈmoon (the moon when it is fully illuminated)
- high ˈschool (a school for older children)
- hot ˈdog (a type of food)
2️⃣ Noun + Noun (when the first noun is a proper noun or material)
Examples:
- silk ˈshirt
- cotton ˈdress
- London ˈbridge
- Italy ˈtour
Exceptions are most compounds ending with -cake, -bread and -juice, for example:
‘cheesecake, ‘gingerbread, ‘ orange ,juice
Stress in Compound Adjectives
Compound adjectives are combinations of words that work together to describe a noun (e.g., well-known author, full-length movie). Most compound adjectives are written with a hyphen, but a few are written as one word.
Main Stress on the First Part
The following types of compound adjectives usually have main stress on the first part:
1️⃣ Compound adjectives usually written as one word
Examples:
- ˈairtight
- ˈcarefree
- ˈchildlike
- ˈpaperless
- ˈairborne
Exceptions: There are some compound adjectives usually written as one word, but do not follow this rule, for example:
- worldˈwide
- nationˈwide
- homeˈmade
2️⃣ Noun + -ing Form
When a noun is combined with an -ing form to create an adjective, the stress generally falls on the noun (first part).
Examples:
- ˈheartbreaking
- ˈtime-saving
- ˈrecord-breaking
- ˈmind-blowing
3️⃣ Noun + Past Participle
In these compounds, a noun is joined with a past participle to form an adjective. The main stress typically remains on the first element (noun).
Examples:
- ˈsun-dried
- ˈwind-blown
- ˈair-conditioned
- ˈvoice-activated
Exceptions: There are some compound adjectives with “noun + past participle” form, but do not follow this rule, for example:
- handˈwritten
- homeˈgrown
- handˈmade
Main Stress on the Second Part
The following types of compound adjectives usually have main stress on the second part:
1️⃣Noun + Adjective
Examples:
- sugar-ˈfree
- sky-ˈhigh
- stress-ˈfree
- smoke-ˈfree
2️⃣ Adjective + noun
Examples:
- high-ˈspeed
- short-ˈrange
- high-ˈtech
- full-ˈlength
3️⃣ Adverb or Adjective + Past Participle
Examples:
- well-ˈknown
- highly-ˈrespected
- brightly-ˈcoloured
- deeply-ˈrooted
- short-ˈchanged
4️⃣ Adverb or adjective + -ing form
Examples:
- good-ˈlooking
- long-ˈlasting
- fast-ˈgrowing
- ever-ˈchanging
- far-ˈreaching
Stress in Compound Verbs
Compound verbs are two words joined together to create one meaning. Unlike compound nouns and adjectives, they are less common, but you’ll still hear them in everyday English.
In most compound verbs, the second element (often a noun or particle) carries the main stress. This is especially true when the verb has an idiomatic or phrasal meaning.
- to underˈstand
- to overˈtake
- to break ˈdown
- to check ˈin
- to look ˈafter
- to give ˈup
Exceptions: Some compound verbs may have first-part stress, particularly when:
- The second word is weak or short.
- The verb is newly formed or stylistically emphasized.
- It’s a back-formation from a compound noun.
Examples:
- ˈbabysit
- ˈtroubleshoot
- ˈsightsee
- ˈhousekeep
