Word Stress Rules: Where to Place the Stress in English Words
Every English word with more than one syllable has one syllable that is stressed more strongly than the others. A stressed syllable is louder, longer, and higher in pitch, and its vowel is pronounced fully. Unstressed syllables are shorter and often reduce to a brief "uh" sound. Correct stress is one of the most effective ways to make your speech clearer.
Two-syllable words
Most two-syllable nouns and adjectives are stressed on the first syllable: table, water, happy, and mountain.
Many two-syllable verbs are stressed on the second syllable: begin, decide, forget, and arrive.
This pattern explains why some words change their stress depending on how they are used. In record, present, object, and permit, the noun is stressed on the first syllable and the verb on the second. See our list of words with two pronunciations for more examples.
Suffixes that affect stress
Certain suffixes place the stress on the syllable immediately before them:
| Suffix | Examples |
|---|---|
| -tion, -sion | education, decision, pronunciation |
| -ic, -ical | economic, specific, political |
| -ity | ability, university, reality |
| -ian | musician, librarian, comedian |
The effect is clear within a single word family: PHO-to-graph, pho-TOG-ra-pher, and pho-to-GRAPH-ic. Each suffix moves the stress to a different syllable.
Other suffixes do not affect the stress, including -ness, -ment, -ful, -less, and -ly. For example, happy becomes HAP-pi-ness, and develop becomes de-VEL-op-ment.
Compound words
Compound nouns are usually stressed on the first part: bedroom, football, and toothpaste. Compound adjectives and many phrasal verbs are stressed on the second part, as in old-FASH-ioned and to give UP.
Common errors
The following words are frequently stressed on the wrong syllable: photographer, comparable, hotel, event, police, development, hypothesis, and catastrophe. Our list of words with unexpected stress includes a tip for each one.
How to practice
These rules provide a useful starting point, but English has many exceptions, so listening remains essential. Play the word, tap once for each syllable, and tap more firmly on the stressed syllable. Then compare your pronunciation with the audio on the word page.
Common questions
How do I know which syllable is stressed in a new word?
Use the rules in this guide as a starting point, then confirm the pronunciation. Every word page on this site highlights the stressed syllable and shows it in capital letters in the respelling.
Can a word have more than one stressed syllable?
Longer words often have a primary stress and a weaker secondary stress, as in ˌpronunciˈation. Only one syllable carries the primary stress.
Why is word stress important?
Listeners rely on stress patterns to recognize words quickly. A word with correct sounds but incorrect stress can be harder to understand than one with a slightly inaccurate vowel.
