**Explanation of Comparative and Superlative Forms:**
* **Comparative:** Used to compare two things. We form it by adding "-er" to the adjective (if it's a short word) or by using "more" before the adjective (if it's a longer word).
* **Superlative:** Used to compare one thing with all the others in a group. We form it by adding "-est" to the adjective (if it's a short word) or by using "most" before the adjective (if it's a longer word).
**Irregular Forms:**
Some words have irregular comparative and superlative forms, like:
* good -> better -> best
* bad -> worse -> worst
* well -> better -> best
