Defining vs. Non-defining Relative Clauses:
- Non-defining clauses give extra, non-essential information about a specific, unique noun (like "The headmaster's pet owl" or "The Moonstone Elixir"). They MUST be separated by commas, and you CANNOT use "that".
- Defining clauses give essential information that tells us which thing we are talking about (like "any owls"). They do NOT use commas, and "that" is the most common relative pronoun to use for things and animals.
