Shadda / تشديد / Tašdīd, also called Shadda / شدة / Sadda, is an optional character of the Arabic script, which is used to represent vowels of texts. It is used to identify the consonant doubling - in the Arabic script is written only one instead of two consonants. In the debate, the doubling ( gemination ) is heard, however, by the consonant is lengthened (just like in Italian ) or remains shortly after. Since the doubling can cause a change in meaning, the Shadda is found in other texts unvokalisierten frequently.

Follow the Shadda a vowel signs ( Fatha, Kasra, damma, Sukun ), this vowel is set to (or in the case of Kasra under ) the Shadda and not directly on or below the consonants.

In scientific transcriptions of Arabic words in the Latin alphabet, the consonant is always doubled for playback; in non-scientific transcriptions of the consonant is simply written to the part, for example in the name of Mohammed (hence the spelling Mohamed ) or in the names of cities Amman; the word " Shadda " itself contains a Shadda. In contrast, the name of the Egyptian football player Gedo is ( d with Shadda on ) usually about - written with easy Konsonsant - about on his jersey.
