Common mistakes for Spanish speakers

Spanish speakers sometimes make mistakes when using ‘to be’ in the past simple, especially with negatives and questions.

• Using ‘did not be’: A common error is to say I didn’t be happy. This is incorrect. The correct form is I wasn’t happy. Remember, ‘to be’ does not use ‘do’ in the past simple for negatives or questions.
• Incorrect word order in questions: Another mistake is to say You were tired? instead of Were you tired? In English questions, ‘was’ or ‘were’ must come before the subject.
• Confusing ‘was’ and ‘were’: Ensure you use was for I, he, she, it そして were for you, we, they. For example, We was late is wrong; it should be We were late.
