In this study, numerals in Uzbek Turkish are discussed in two parts. In the first part, counting numbers are examined from the following aspects: The concepts related to numbers in Uzbek grammars and how these numbers are handled, the usage characteristics of numbers such as yuz “hundred”, ming “thousand”, million “million” and milliard “billion”, usage of nouns that qualified numbers via +lar and +lab suffixes and the differences in meaning caused by this situation, numbers in reduplications, other words that express numbers, properties of the word yarim “half”, properties of the number bir “one”, morphemes derived from the number bir "one", different uses seen in spoken language, special pronunciations in the language of the Uzbek minority in Southern Turkestan (Afghanistan), spelling rules for numbers in written language, distributive numeral adjectives without a special addition, etc. In the second part of the article, the derivational suffixes that come to the numbers are discussed. It is not common to derive verbs from numbers in Uzbek Turkish. There are only birlash-, birik-, ikkilan- verbs. However, suffixes that derive names from numbers are more than many Turkish dialects. These are as follows, in alphabetical order: +ala and its derivatives (+aladan), +on(ta) / +or(ta), +ov and its derivatives (+ovlon, +ovlab, +ovlashib), (+)ovora, (+)burchak, +lamchi, +lanchi, +(i)nchi, +ta and its derivatives (+tadan, +tacha, +talab, +tayam,+tagina), +lik. The ovora and burchak in this list are not originally suffixes, but are used as suffixes over time. Some of these suffixes can be grouped in terms of function: +ala (and its derivatives) +ov (and its derivatives), the (+)ovora suffixes derive adjectives, pronouns or adverbs that express the community (jamlovchi sonlar). In addition, +lamchi, +lanchi, +(i)nchi suffixes derive ordinal number (tartib sonlar) adjectives. Therefore, while examining the suffixes in this section, the relevant suffixes are handled in groups, not in the above alphabetical order.
