Bonjour Kyaw, a proper noun, i.e. a person's name, will use the third person singular. Let's look at some examples: J'ai un chien. I have a dog. So if we want to state that Jean has a dog, then the phrase becomes «Jean a un chien» Nous avons deux chats. We have two cats. In speaking about my family, to use a common noun, Ma famille a deux chats or Nous avons deux chats. or how about «the house has a roof» la maison a un toit. Elle a une souris. She has a mouse. In these examples, except for nous, they all use the third person singular. With nous it takes the first person plural, nous avons. I hope this helps, Bonne chance, Ron

Merci prof. It helps. So if the subject is plural proper nouns such as John et Alice or plural common nouns such as La maisons, which verbs can we use to be compatable with.

Do they use third person plural?
