Language, which is a living being, maintains its existence by adapting to changing and developing conditions. Human beings need to create new words constantly from the moment they start speaking with words. In Turkic languages, where words are made in many ways such as formulaicity, combining, mixing, abbreviation, compilation, scanning, analogy, the derivation method is used the most. It is possible to see that words are given more than one meaning in every language. On the other hand, every word used in Turkish has a basic meaning element. Over time, people attribute new meanings to words in order to explain concepts more effectively, more concretely and more easily. This situation is called polysemy. The number "bir", which is the subject of the study, has become a polysemous concept by taking both inflectional and inflectional suffixes and by using it in new meanings and tasks in a simple form in the historical process. The aim of this article is primarily to focus on the views on the etymology of the number "bir". Then, it will be focused on how the word is evaluated in Uzbek Turkic grammars and in what meanings it is used, and finally, the morphological analysis of words derived from a number in Uzbek Turkic will be made. While giving the meanings of each word examined in the study, Uzbek Tiliniñ Izåhli Luġati I was taken as a basis. In addition, example sentences from literary texts for each word are given by transferring them to Turkish.
