If you speak Ukrainian, some English grammar rules will feel natural and others will feel confusing. These are the biggest differences to focus on first.
Ukrainian word order is flexible because grammatical cases mark the role of each word. English word order is fixed โ position determines meaning. Ukrainian speakers must resist the urge to rearrange English sentences freely.
Ukrainian has no articles at all. Definiteness and indefiniteness are expressed through word order, demonstratives, and context. English articles must be learned as a completely new grammatical concept.
Ukrainian has both perfective and imperfective aspects for verbs โ each verb has two forms expressing completed or ongoing action. English uses tense alone to make these distinctions, with no separate aspect forms.
