Damma
Ḍamma (ضَمَّة) is an optional character in the Arabic script that is used to vocalize text. It is used to identify the short vowel u (as in "round"). The Ḍamma, modeled after a waw , is placed like most of the other auxiliary signs above the consonant to be vocalized (indicated as a circle in the graphic). A Ḍamma above the letter preceding a waw indicates that a long ū is being spoken, rather than an au or aw , which would be substituted for a fatha .
A damma is also used to denote the nominative ending -u (for determinate nouns and adjectives). If the nominative ending is indeterminate, the ending is -un , and two dammas ( dammatān , see also nunation ) are set; In the publication, a separate symbol is usually used, a damma with a tick.
In Persian the sign is called Zamme , which means Ḍamma in Persian pronunciation, or Pīsch and stands for a short o . The Turkish name is Ötre .
