Quick Answer
The word “or” is a conjunction used to show a choice, alternative, or possibility between two or more things.
For example:

In simple terms, “or” connects options. It tells the reader or listener that there is more than one choice.

This is the most common use.

👉 Here, the speaker is offering two options.
2. To Show Possibility
Sometimes, “or” suggests different possible outcomes.
- Hurry up, or you will miss the train. (UK)
