In a longer word, one syllable is said with more force than the others. That syllable is louder, longer, and usually clearer, while the other syllables become weaker. In table, the first syllable carries the stress: TAble. In about, the second syllable is stronger: aBOUT. English listeners depend on this pattern to hear words quickly and clearly, so stress is part of the word itself, not an extra style choice.

Basic word stress pattern

Example	Pattern
In banana, the second syllable is stronger.	In a word with more than one syllable, one syllable is said more strongly than the others.
I said present clearly, so you understood it.	Word stress helps listeners hear the word clearly.

Many multi-syllable nouns and adjectives are stressed on the first syllable. TAble, DOCtor, HAPpy, CLEver, MILlion. The stressed syllable sounds fuller, and the other syllables move back. This pattern is common enough that it helps when you meet a new word in a dictionary or in print. For pronunciation, compare the strong first syllable in WINdow with the weaker second syllable, and notice the same shape in adjectives like BEAUtiful and TALented.

First syllable stress in nouns and adjectives

Word	Notation	Description	Example
TAble	ˈteɪ bəl	The first syllable is stressed and the second syllable is weaker.	Please put the book on the table.
HAppy	ˈhæ pi	The first syllable is stressed and the second syllable is lighter.	She feels happy today.

Many two-syllable and three-syllable verbs are stressed on the second syllable. reLAX, beGIN, exPLAIN, deCIDE, aRRIVE. The first syllable becomes lighter and shorter, while the stressed syllable gets the main beat. This pattern is very common in action words, especially when they end in a weak syllable before the stress. Compare REcord as a noun with reCORD as a verb, and notice how the verb pulls the stress later in the word.

Second syllable stress in verbs

Word	Notation	Description	Example
reLAX	rɪˈlæks	The second syllable is stressed and the first syllable is weak.	You should relax after work.
deCIDE	dɪˈsaɪd	The second syllable is stressed and the first syllable is weak.	I need to decide soon.

Some related word pairs change stress when the word changes class. A noun or adjective often takes first-syllable stress, while the related verb takes later stress: PREsent and preSENT, REcord and reCORD, CONtract and conTRACT. The spelling stays the same, but the stress shifts and the meaning changes. In speech, that shift tells the listener whether the word names a thing or describes an action.

Stress shifts in related word pairs

Word	Notation	Description	Example
CONtract	ˈkɒn træt	The first syllable is stressed when the word is a noun.	I signed the contract yesterday.
conTRACT	kənˈtrækt	The second syllable is stressed when the word is a verb.	We will contract the work to a local team.

Short grammar words usually do not take strong stress in normal speech. Words like to, for, and, of, a, the, at, and can are often weak because they carry grammar rather than new content. In I want to go, the main beat is on want and go, while to is soft and quick. In connected speech, these words often sit between stronger content words and lose their full, careful form. For more on how stress shapes whole sentences, see Rhythm and Meter.

Unstressed syllables often change their vowel quality. The most common weak vowel is schwa, the short relaxed sound /ə/, as in the second syllable of about or the last syllable of teacher. Another common reduced sound is a short /ɪ/, especially in endings like -in in listen or -it in rabbit. These weak vowels are shorter and less distinct than full vowels. The spelling may still show a, e, i, o, or u, but the spoken sound becomes reduced, which is one reason English spelling can seem irregular. This pattern also connects closely with Silent Letters and Common Spelling Patterns.

Reduced vowels in unstressed syllables

Word	Notation	Description	Example
about	əˈbaʊt	The first syllable uses schwa instead of a full vowel.	We talked about the plan.
kitten	ˈkɪ tən	The second syllable uses a reduced vowel sound instead of a strong full vowel.	The kitten is sleeping.

In many compound words, the first part gets the main stress. BLACKboard, POSTcard, AIRport, FIREman, TOOTHbrush. The two parts act like one new word, so the first part leads and the second part follows with less stress. Compare green HOUSE for a building with GREENhouse for a place where plants grow. Stress tells the listener whether the two words are separate or belong together as one compound.

First part stress in compounds

Example	Pattern
I bought a toothbrush yesterday.	In many compound words, the first part is stressed more strongly than the second part.
My bedroom is upstairs.	Compound stress can help listeners hear one idea as a single word.

English sentences usually have a strong beat on content words and weak forms on grammar words. Nouns, main verbs, adjectives, and adverbs carry the stress: I BOUGHT a NEW CAR YESTERday. The small words between them lose force, so the sentence flows in a pattern of strong and weak beats. This rhythm helps English sound natural and keeps the important words easy to hear. Compare that with a careful list or a slow, clear speech style, where more words may sound full, but the normal rhythm still leans toward the content words.

The last major stress in a sentence usually falls on the newest or most important information. In I bought a car, the main stress is on car. If the answer changes, the stress moves: I bought a CAR, I bought a RED car, I BOUGHT a car. This final strong beat is called nuclear stress. It tells the listener which part of the message matters most and which part is being corrected, compared, or introduced.

Some words have more than one accepted stress pattern, and British and American English may prefer different forms. adVERtisement is common in British English, while ADvertisement is common in American English. laBORatory and LABoratory also vary by region, and the same is true for some longer academic or formal words. Both patterns can be correct, but one may sound more natural in a particular variety. When learning a new word, it helps to check the stress pattern for the variety you want to use most often.
