Study summary This study examines the names of regions in the Emirate of Dubai in the United Arab Emirates, with the aim of identifying the phonetic and semantic phenomena of these names, knowing their meanings and the reasons for their naming, and linking the meaning of the word in the language and dialect. One of the most important motivations for preparing it was to show respect for this ancient emirate, and to serve it by studying the names of its regions in a linguistic study, and then to serve the linguistic study in its social field. This is because the relationship between language and society is interconnected, and there is a correlation between them that makes each of them grow with the growth of the other, advance with its elegance, and weaken with its weakness. A society without language, and there is no language without society. In this thesis, I have been keen to study nouns in a descriptive and analytical study from their phonological and semantic aspects. The phonological level examines the word in terms of the phonetic changes for each of the sounds and movements and the reasons for that, and the semantic level examines the lexical, suggestive, and social connotations and their development, and also examines the reasons for naming. And the link between linguistic and dialect meaning.
