Take as an instance aspiration. In uttering this word we give a marked
emphasis of the voice upon the first and third syllables, and
therefore those syllables are said to be accented. The first of these
accents is less distinguishable than the second, upon which we dwell
longer, therefore the second accent in point of order is called the
primary, or chief accent of the word.
