## 📘 Understanding the Task

We are working with two common prefixes: un- and dis-.
Both usually mean “not” or “opposite of,” but sometimes one is more commonly used with certain words.

- un- is often used with adjectives and some verbs (e.g., *unhappy, unzip, unfair*)
- dis- is often used with verbs and nouns, especially those of Latin origin (e.g., *disagree, discomfort, distrust*)

We’ll add the correct prefix to each base word to form a real, meaningful English word.

## 💡 Quick Tip for Learning Prefixes:

- un- often goes with simple, everyday words (*unhappy, unfair, unripe*).
- dis- often goes with more formal or Latinate words (*disagree, distrust, discomfort*).

You can also think: if the word feels like it needs a “not” meaning, try both prefixes — but check which one actually exists in English!
