In Ukrainian grammar, Бути and Стати are two very important verbs that mean “to be” and “to become” respectively. The verb “Бути” is an irregular verb and is used in various contexts, often indicating a state or existence of a subject. “Стати”, on the other hand, is a regular verb which talks about changing states, conditions, or even professions. It is essential for students learning Ukrainian to have a good grasp of these verbs, as they are integral to forming sentences and expressing thoughts in the language.
