In linguistics, stress is the relative emphasis that may be given to certain syllables in a word. It comprises five features:
It is l-o-n-g-e-r – com-p-u-ter
It is LOUDER - comPUTer
It has a change in pitch from the syllables coming before and afterwards. The pitch of a stressed syllable is usually higher.
It is said more clearly. The vowel sound is purer. Compare the first and last vowel sounds with the stressed sound.
It uses larger facial movements. Look in the mirror when you say the word. Look at your jaw and lips in particular.
