Accent is the emphasis placed upon a syllable in pronunciation. The term is often used as a synonym for 'stress', although some theorists prefer to use 'stress' only for metrical accent. Three kinds of accent may be distinguished, according to the factor that accounts for each:
1. Etymological accent (or 'word accent') is the emphasis normally given toa syllable according to the word's derivation or morphology.
2. Rhetorical accent (or 'sense accent') is allocated according to the relative importance of the word in the context of a sentence or question.
3. Metrical accent (or stress) follows a recurrent pattern of stresses in a verse line.
