Which
* Use "which" when referring to a choice between things or when introducing a clause that provides more information about a noun.
* Example: "Which cake would you like?" (Choice between cakes)
* Example: "The book, which I bought last week, is really interesting." (Provides more info about the book)
Witch
* Use "witch" when referring to a supernatural being, often associated with magic or sorcery.
* Example: "The witch cast a spell on the village."
Here are some examples to illustrate the difference:
* Which: "Which color do you prefer, blue or green?"
* Witch: "The old witch lived in a dark forest."
* Which: "The house, which is painted red, is on the corner."
* Witch: "The witch's potion bubbled ominously in the cauldron."
Remember: "Which" is used for choices and further description. "Witch" is used for a specific supernatural being.
