9. Use of Tenses

Mistakes in English use of tenses happen when speakers mix up past, present, and future timeframes. A common error is switching tenses mid-sentence, such as starting a story in the past tense and suddenly shifting to the present tense without a clear reason. Another mistake is misusing the past simple and present perfect, like saying "I went there yesterday" instead of the correct version. These errors confuse listeners and change the timeline of events, making clear communication difficult.
