Let's break down the common ways "or" is used in English:
1. "Or" as a conjunction: This is the most common use. It connects two or more options, phrases, or clauses. It's used to present alternatives:
* Example: "Would you like tea or coffee?"
* Example: "I'm going to the store or to the library."
* Example: "He's either at home or at work."
2. "Or" in negative sentences: This is a bit trickier. When using "or" in a negative sentence, it often means "neither."
* Example: "He doesn't like apples or oranges" means he likes neither apples nor oranges.
3. "Or" in informal writing: You might see "or" used in informal writing or speech in place of "either/or".
* Example: "You can have this or that" (instead of "You can have either this or that").
