Stress is extremely important in English. Stressing the wrong syllable or pronouncing all syllables with equal stress are a common problem for non-native speakers. So how can I tell which syllable to stress?

Although the rules for stress are very complicated and have many exceptions, there are a few common patterns that are easy to remember.

WORD STRESS
Every word has one stressed syllable which is pronounced louder, longer and higher.

Stress on 1st syllable:
Two-syllable nounslabel, format, table, coffee, breakfast
Two-syllable adjectiveslucky, grateful, handsome, boring, silly
Two-syllable adverbsoften, sometimes, mostly, rarely, never
Compound nounstoothpaste, bookshelf, sunshine, headset
Stress on 2nd syllable:
Two-syllable verbsinvent, reply, decide, persuade, divide
Phrasal verbspass out, give up, turn off, give in

USING GRAMMAR TO PREDICT STRESS
Sometimes, the same word can be either a noun or a verb. In general, nouns stress the first syllable, verbs, the second.
