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 nouns label, format, table, coffee, breakfast
Two-syllable adjectives lucky, grateful, handsome, boring, silly
Two-syllable adverbs often, sometimes, mostly, rarely, never
Compound nouns toothpaste, bookshelf, sunshine, headset
Stress on 2nd syllable:
Two-syllable verbs invent, reply, decide, persuade, divide
Phrasal verbs pass 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.

Nouns Verbs Nouns Verbs
CONvict conVICT REcall reCALL
CONduct conDUCT CHECKout check OUT
INsult inSULT PROduce proDUCE
RUNdown run DOWN SUSpect susPECT

Notice the stress in the following noun/verb pairs.

  1. When someone insults me, I don’t take the insult very well.
  2. Someone should conduct an investigation into his conduct.
  3. I suspect the suspect will want to call a lawyer.
  4. I don’t recall the beef recall of the 1990’s.
