If you speak Telugu, some English grammar rules will feel natural and others will feel confusing. These are the biggest differences to focus on first.
Telugu is strictly SOV — the verb always appears at the end. 'Nenu cinema chustanu' literally means 'I film watch'. English requires the verb in the middle — 'I watch a film'. Every Telugu sentence structure must be completely rearranged.
Telugu has no articles. Definiteness is shown through demonstratives and context. English articles 'a', 'an', and 'the' are a grammatical layer that Telugu speakers must build from scratch.
Telugu verbs change based on the gender and number of the subject. Telugu also has honourific and non-honourific verb forms. English verbs have none of these features — just tense and the third-person singular -s.
