Yemeni Arabic
The Hadhrami dialect in many towns and villages in the "Wādī" (valley) and the coastal region is characterised by its pronunciation of the voiced palatal plosive (or affricate) (ج) as the semi-vowel (ي) ("y") (). In this it resembles some Eastern Arabian and Gulf dialects including the dialects of Basra in Iraq, Kuwait, Qatar, Bahrain and the dialects of the other Arab Emirates. In educated speech, (ج) is realised as a voiced palatal plosive () or affricate () in some lexical items.
