Common mistakes to avoid
1. He clean ❌
With he, she and it, the verb needs -s (or -es): he cleans, she cleans, it cleans. The same is true with one person or one thing: my friend cleans. This is one of the most common mistakes in English, so always check your verb.
2. Does she cleans? ❌
In a question or a negative, the -s is already on does. So the main verb goes back to the base form: Does she clean…?, She doesn't clean. Never put -s on both verbs.
3. I am agree ❌
In the Present Simple, do not put am, is or are before the verb. Say I agree, not I am agree. With clean, say I clean, she cleans. Use am, is or are with an -ing form (I am reading) or with an adjective (I am happy).
