Remember that we add s or es for he, she and it. Sometimes we also change y to i. My favourite TV show starts at 8 o'clock. She finishes work early on Fridays. My brother studies…

You're absolutely right! In English, we generally add "s" or "es" to the base form of a verb when the subject is in the third person singular (he, she, it). Here are a few points to remember:

1. Basic Rule: For most verbs, we simply add "s" for third person singular, e.g., "He plays," "She runs."

2. Verbs ending in -o, -ch, -sh, -ss, -x: We add "es" to these verbs, e.g., "He goes," "She watches," "It finishes."

3. Changing y to i: If a verb ends in a consonant + "y," we change the "y" to "i" and add "es," e.g., "He flies" becomes "He flyes." However, if the verb ends in a vowel + "y," we simply add "s," e.g., "He plays."

Here are the examples you provided, showing correct usage:

• "My favourite TV show starts at 8 o'clock."
• "She finishes work early on Fridays."
• "My brother studies at university."
