7 Word stress rules in English language

Category: Pronunciation

To communicate clearly when you are speaking in English, it’s important to stress the correct syllables in each word. All words of more than one syllable have what is called word stress. 
This means that at least one of the syllables is longer and louder than the other syllables. Basically, stressing means to emphasize a sound.

Uses:

• Communicating clearly and accurately.
• Understanding meaning (PRE - sent is a gift, pre - SENT is an action).

There are three very important rules about word stress:

• One word, one stress.
• The stress is always on a vowel.
• Prefixes and suffixes are never stressed.

Here are some rules for stressing:
​

Most two-syllable nouns and adjectives
Stress on the first syllable.
 
Examples:
AP-ple
PRE-sent
HA-ppy
CLE-ver

RULE #2
Most two-syllable verbs and prepositions
Stress on the last syllable.
 
Examples:
re-QUIRE
pre-SENT
be-TWEEN

RULE #3
Three-syllable nouns
