What to watch for
- A synonym is exactly the same word.

- An antonym is any word that is different.
- Help: An antonym must be the opposite in meaning, not just different.
- Adding un- always makes a word negative.
- Help: un- means 'not' or 'opposite of', so it often makes a negative, but not always.
