Al-dād is a unique sound in Arabic. It is believed that this sound is what makes Arabic a distinguished language. However, its description has confused the linguists for long time. Some modern linguists believe that al-dād described by the ancient linguists is not used in the present time. On the other hand, Arabic speakers may not know that the sound they use for the classical pronunciation of al-dād is not the one described by the ancient Arab linguists. This study records the existence of a sound that has the features of al-dād as described by the ancient Arab linguists. It is used among some speakers in Southwest Saudi Arabia.
