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