Rules of Sentence Stress


The basic rules of sentence stress are :
  1. content words are stressed
  2. structure words are unstressed
  3. the time between stressed words is always the same
Examples of content words and are structure words :

Content words - stressed

The main idea                   Example
main verbsSELL, GIVE, EMPLOY
nounsCAR, MUSIC, MARY
adjectivesRED, BIG, INTERESTING
adverbsQUICKLY, LOUDLY, NEVER
negative auxiliariesDON'T, AREN'T, CAN'T


Structure words - unstressed

Words for correct grammarExample
pronounshe, we, they
prepositionson, at, into
articlesa, an, the
conjunctionsand, but, because
auxiliary verbsdo, be, have, can, must

Exceptions

The above rules are for "neutral" or normal stress. But sometimes we can stress a word that would normally be a structure word, for example to correct information. For example :
"They've been to Mongolia, haven't they?"
"No, THEY haven't, but WE have.
Note also that when "be" is used as a main verb, it is usually unstressed (even though it is a content word).
