📊 Stress & Intonation
Learn where to put emphasis and how to use intonation to sound more natural. Proper stress patterns improve comprehension and fluency.
Sound More Natural & Fluent
Word stress and intonation are the "music" of English. Master them to sound more natural and native-like. Read our comprehensive guide to English stress and intonation to understand the patterns deeply.
Two systems, two different kinds of failure
Word stress is a fixed property of a word, listed in dictionaries, and getting it wrong can stop listeners recognising the word at all. Intonation is chosen freshly for every utterance and signals attitude, focus and sentence type; getting it wrong usually leaves you understood but changes how you come across.
If you have limited practice time, word stress gives the faster return, and correcting it often improves intonation automatically, because the main pitch movement of a phrase lands on the stressed syllable of the focused word.
Word stress rules that cover most vocabulary
| Ending | Stress | Examples |
|---|---|---|
| -tion, -sion, -cian | Syllable before | eduCAtion, deCIsion, muSIcian |
| -ity, -ety | Syllable before | aBILity, uniVERsity |
| -ic, -ical | Syllable before | ecoNOMic, hisTORical |
| -graphy, -logy | Third from end | phoTOgraphy, bioLOgy |
| -ee, -eer, -ese | On the ending | employEE, engiNEER, JapanESE |
| -ment, -ness, -ful, -able, -ly | No change | deVELopment, HAPPily |
Around a hundred words shift stress between noun and verb: a REcord but to reCORD, a PRESent but to preSENT. Compound nouns take stress on the first element, so a GREENhouse is a building for plants while a green HOUSE is a house that is green.
Intonation: the rule most courses get wrong
Statements fall, and so do wh- questions. Where do you live? ends low, exactly like a statement. Only yes/no questions rise reliably. A rising wh- question is not neutral — it signals surprise or a request to repeat.
| Type | Pattern | Example |
|---|---|---|
| Statement | Fall | I live in Lisbon. |
| Wh- question | Fall | Where do you live? |
| Yes/no question | Rise | Do you live here? |
| Unfinished list | Rise, then fall on the last item | bread, milk, and eggs |
| Reservation, politeness | Fall-rise | It's a good idea... |
Sentence stress marks what is new
The default main stress falls on the last content word. When something is already known from context, the stress moves earlier onto whatever is new. What's that? gets It's a new PHONE; Is that your old phone? gets It's a NEW phone. Placing stress randomly does not merely sound accented — it asserts contrasts you did not intend.
Exercises
- Tapping. Read aloud while tapping once per stressed syllable. Unstressed material must compress into the gaps.
- Humming. Hum a sentence using only pitch and length. If the hum sounds like English, the rhythm is right.
- Contrast drill. Say I didn't say she stole the money seven times, stressing a different word each time, and state the implied meaning aloud.
- Backchaining. Build long sentences from the end to protect the rhythm of the ending.
