Imagine reading these two sentences:

  • I wanted to go outside.
  • It was raining.

Both sentences make sense on their own, but they feel disconnected.

Now read:

"I wanted to go outside, but it was raining."

The word but connects the two ideas and shows a relationship between them.

Words like but are called conjunctions.

Conjunctions are important because they help us join words, phrases, and sentences smoothly, making our communication clearer and more natural.
