Adverbs and adjectives can be a bit tricky, but here's a simple way to look at them: adjectives describe nouns (like "happy cat"), while adverbs describe verbs, adjectives, or other adverbs (like "happily running"). Adverbs often end in -ly, but not always. Do you have any specific sentences or examples you're curious about? It's fun to see how language can change with just a slight tweak!
