Common Mistake: 3rd person verb (base verb) after what/who

One common grammatical mistake that many people make is using the base verb form (also known as the infinitive form) after words like "what" or "who" when referring to the third person.

When we ask a question about someone or something in the third person, we need to use the correct verb form to match. This rule applies to both present and past tenses.

Examples:

• Mistake: What she do next? (Base verb form - "do")
• Correction: What does she do next? (Third-person verb form - "does")

• Mistake: Who they call yesterday? (Base verb form - "call")
• Correction: Who did they call yesterday? (Third-person verb form - "did")

This mistake commonly occurs when we forget to add the appropriate helping verb (such as "does" or "did") to form a question or negate a sentence. Using the correct verb form is essential for maintaining proper grammar and clear communication.
