Word Stress in English
Word stress is your magic key to understanding spoken English. Native speakers of English use word stress naturally. Word stress is so natural for them that they don`t even know they use it. Non-native speakers who speak English to native speakers without using word stress, encounter two problems:
They find it difficult to understand native speakers, especially those speaking fast.
The native speakers may find it difficult to understand them.
Understanding Syllables
To understand word stress, it helps to understand syllables. Every word is made from syllables. Each word has one, two, three or more syllables.

Notice that (with a few rare exceptions) every syllable contains at least one vowel (a, e, i, o or u) or vowel sound.

What is Word Stress?
In English, we do not say each syllable with the same force or strength. In one word, we accentuate ONE syllable. We say one syllable very loudly (big, strong, important) and all the other syllables very quietly.
Let`s take 3 words: photograph, photographer and photographic. Do they sound the same when spoken? No. Because we accentuate (stress) ONE syllable in each word. And it is not always the same syllable. So the shape of each word is different.

This happens in ALL words with 2 or more syllables: TEACHer, JaPAN, CHINa, aBOVE, converSAtion, INteresting, imPORtant, deMAND, etCETera, etCETera, etCETera
The syllables that are not stressed are weak or small or quiet. Native speakers of English listen for the STRESSED syllables, not the weak syllables. If you use word stress in your speech, you will instantly and automatically improve your pronunciation and your comprehension.
Try to hear the stress in individual words each time you listen to English - on the radio, or in films for example. Your first step is to HEAR and recognise it. After that, you can USE it!
There are two very important rules about word stress:
One word, one stress. (One word cannot have two stresses. So if you hear two stresses, you have heard two words, not one word.)
The stress is always on a vowel.



Why is Word Stress Important?
Word stress is not used in all languages. Some languages, Japanese or French for example, pronounce each syllable with eq-ual em-pha-sis.
Other languages, English for example, use word stress.
Word stress is not an optional extra that you can add to the English language if you want. It is part of the language! English speakers use word stress to communicate rapidly and accurately, even in difficult conditions. If, for example, you do not hear a word clearly, you can still understand the word because of the position of the stress.
Think again about the two words photograph and photographer. Now imagine that you are speaking to somebody by telephone over a very bad line. You cannot hear clearly. In fact, you hear only the first two syllables of one of these words, photo... Which word is it, photograph or photographer? Of course, with word stress you will know immediately which word it is because in reality you will hear either PHOto... or phoTO... So without hearing the whole word, you probably know what the word is ( PHOto...graph or phoTO...grapher). It`s magic! (Of course, you also have the `context` of your conversation to help you.)
This is a simple example of how word stress helps us understand English. There are many, many other examples, because we use word stress all the time, without thinking about it.



Where do I Put Word Stress?
There are some rules about which syllable to stress. But...the rules are rather complicated! Probably the best way to learn is from experience. Listen carefully to spoken English and try to develop a feeling for the "music" of the language.
When you learn a new word, you should also learn its stress pattern. If you keep a vocabulary book, make a note to show which syllable is stressed. If you do not know, you can look in a dictionary. All dictionaries give the
