DIAERESES

A diacritic ( ¨ ) placed over a vowel letter (especially the second of two consecutive ones) indicating that it is sounded separately, usually forming a distinct syllable, as in the English words naïve, Noël and Brontë, the French haïr and the Dutch ruïne.

Distraction; the separation of a vowel, often a diphthong, into two distinct syllables.

A natural break in rhythm when a word ends at the end of a metrical foot, in a line of verse.
