What you'll learn

  1. 1

    Imagine a big, strong train 🚂 — that's a MAIN clause. It can travel all by itself and makes sense on its own.

  2. 2

    Which of these is a main clause — a sentence that makes sense on its own?

  3. 3

    Now a SUBORDINATE clause is like a little wagon 🚃 attached to the big train. It cannot travel alone — it needs the main train to make sense!

  4. 4

    Let's join a main clause and a subordinate clause together! 🧩

  5. 5

    Tap the subordinate clause — the little wagon that can't go alone. 🚃

  6. 6

    Which is the subordinate clause in this sentence: 'Sam laughed when the clown fell over.'?
