Present Simple of "be"

1. What Is the Verb “Be”?

The verb “be” is very common in English. We use it to talk about a person’s name, job, age, feelings, location, nationality, the weather, the time, and other basic information.

In the present simple, “be” has three forms:

• am
• is
• are

The verb “be” is special because it changes with the subject:

• I am
• he/she/it is
• you/we/they are

2. When Do You Use the Present Simple of “Be”?

You use am / is / are to talk about:

• Job — what someone is
  • “I am a teacher.” / “They are doctors.”
• Name — saying your name
  • “I am Sam.”
• Feelings — how someone feels
  • “She is happy.”
• Description — describing people or things
  • “Our car is white.” / “She is nice.”
• Age — saying how old someone is
  • “He is 10 years old.”

• Weather — talking about the weather

After be, we often use a noun (a word for a person or thing: a teacher), an adjective (a describing word: happy), or a place (a location: at home).
