Word stress is one of the most important aspects of English pronunciation, yet it is often overlooked by learners. Placing stress on the wrong syllable can make a word unrecognizable or change its meaning entirely. This guide will help you understand English word stress patterns and give you practical rules to follow.
This post is part of our Music of English series on prosody and pronunciation.
What is Word Stress?
Word stress means making one syllable in a word stand out more than the others. In English, stressed syllables are:
- Louder than unstressed syllables
- Longer in duration
- Higher in pitch
- Clearer in vowel quality (unstressed vowels often reduce to schwa /ə/)
Compare: BA-na-na (stress on first syllable) vs. ba-NA-na (stress on second, which is correct).
Why Word Stress Matters
English is a stress-timed language, meaning native speakers expect stressed syllables to occur at regular intervals. When word stress is wrong:
- Listeners may not recognize the word at all
- The meaning may change completely
- Your speech sounds "foreign" even if individual sounds are correct
Stress Changes Meaning: Noun vs. Verb Pairs
Many English words can be either nouns or verbs, with stress determining the difference. Generally, nouns have stress on the first syllable, and verbs have stress on the second.
More Noun/Verb Pairs
| Word | Noun (first syllable) | Verb (second syllable) |
|---|---|---|
| object | /ˈɑːbdʒekt/ (a thing) | /əbˈdʒekt/ (to disagree) |
| project | /ˈprɑːdʒekt/ (a task) | /prəˈdʒekt/ (to display) |
| produce | /ˈprɑːduːs/ (vegetables) | /prəˈduːs/ (to make) |
| subject | /ˈsʌbdʒekt/ (a topic) | /səbˈdʒekt/ (to expose to) |
| desert | /ˈdezərt/ (sandy land) | /dɪˈzɜːrt/ (to abandon) |
| content | /ˈkɑːntent/ (material) | /kənˈtent/ (satisfied) |
Rules for Two-Syllable Words
While there are exceptions, these patterns help predict stress in two-syllable words:
Nouns and Adjectives: Usually First Syllable
Verbs: Often Second Syllable
Stress Patterns in Longer Words
Longer words follow more complex patterns. Here are the most reliable rules:
Suffixes That Do Not Change Stress
These suffixes are added to words without changing the original stress position:
- -er, -or, -ar: TEACHer, DOCtor, POPular
- -ly: QUIETly, BEAUtifully
- -ment: GOVernment, DEvelopment
- -ness: HAPpiness, SADness
- -ful: BEAUtiful, WONderful
- -less: HELPless, CAReless
Suffixes That Pull Stress to the Syllable Before Them
These suffixes attract stress to the syllable immediately preceding them:
- -tion, -sion: eduCA-tion, deci-SION
- -ic: fanTAS-tic, draMAT-ic
- -ical: poLIT-ical, pracT-ical
- -ity: aBIL-ity, possiBIL-ity
- -ious, -eous: deLIC-ious, gorGEous
Suffixes That Take the Stress Themselves
Some suffixes are always stressed:
- -ee: refuGEE, employEE
- -eer: enginEER, voluntEER
- -ese: JapanESE, PortuguESE
- -ette: cassETTE, silhouETTE
Compound Words
Compound words (two words combined) usually stress the first element:
Compare this to adjective + noun phrases, which stress the noun:
- GREENhouse (compound, a building) vs. green HOUSE (phrase, a house that is green)
- BLACKbird (compound, a species) vs. black BIRD (phrase, any bird that is black)
Common Stress Mistakes by Spanish Speakers
Spanish speakers often make predictable stress errors because Spanish stress patterns are more regular:
| Word | Wrong Stress | Correct Stress |
|---|---|---|
| comfortable | com-FOR-ta-ble | COM-for-ta-ble /ˈkʌmftəbəl/ |
| interesting | in-te-RES-ting | IN-te-res-ting /ˈɪntrəstɪŋ/ |
| vegetable | ve-ge-TA-ble | VE-ge-ta-ble /ˈvedʒtəbəl/ |
| development | de-ve-LOP-ment | de-VE-lop-ment /dɪˈveləpmənt/ |
| photography | pho-to-GRA-phy | pho-TO-gra-phy /fəˈtɑːɡrəfi/ |
| advertisement | ad-ver-ti-SE-ment | ad-VER-tise-ment /ədˈvɜːrtɪsmənt/ |
