Lesson Content

Grammar Focus

Basic conjunctions join ideas in simple sentences. They help you explain your thoughts clearly and make your sentences complete.

  • And connects two similar ideas:
    “I like pizza and pasta.”
  • But shows a difference or surprise:
    “I like tea but not coffee.”
  • Or gives a choice between things:
    “Do you want juice or water?”
  • So shows the result of something:
    “It was cold, so I wore a jacket.”
  • Because is a subordinating conjunction. It introduces a reason and connects a dependent idea to the main sentence:
    “I stayed home because I was sick.”

🎧🗣️ Why This Grammar Matters for Listening and Speaking

Basic conjunctions are very important in everyday English because they connect ideas in sentences, making conversations easier to understand. When you listen, these words help you follow what someone is saying, and when you speak, they help you explain your thoughts clearly.

  • When talking with friends, family, or teachers, you often need to add information to give more details:
    “I like apples and bananas.”
    “She plays the guitar and sings.”
    This helps your listener understand all parts of your idea.

  • To show a difference or surprise between ideas, use “but”:
    “I wanted to go to the park, but it started to rain.”
    “He likes coffee, but she prefers tea.”
    This shows that two ideas are not the same or opposite.

  • When making choices or asking questions, “or” gives clear options:
    “Do you want water or juice?”
    “Should I call you today or tomorrow?”
    This helps the listener know what you are offering or deciding between.

  • To explain cause and effect, “so” shows what happens because of something else:
    “I was tired, so I went to bed early.”
    “It’s cold outside, so wear a jacket.”
    This helps listeners understand the reason behind an action or result.

  • “Because” is important to give reasons in explanations:
    “I stayed home because I was sick.”
    “She left early because she had a meeting.”
    This helps your listener understand why something happened.

Using these conjunctions naturally in your speaking makes your sentences longer and your meaning clearer. When you hear these words in conversations, stories, or instructions, they signal how ideas are connected, helping you understand better. Practicing with these conjunctions will improve your ability to talk about your thoughts and follow others in everyday English.
