Here's how it works:
* Adjectives describe nouns: *beautiful*, *happy*, *slow*
* Adverbs describe verbs, adjectives, or other adverbs: *beautifully*, *happily*, *slowly*
Examples:
* Adjective: *quick*
* Adverb: *quickly*
* Adjective: *gentle*
* Adverb: *gently*
* Adjective: *careful*
* Adverb: *carefully*
Important Notes:
* Some words that end in "-ly" are not adverbs but adjectives (e.g., *friendly*, *lovely*, *ugly*).
* Not all adverbs end in "-ly" (e.g., *very*, *quite*, *too*).
* Adding "-ly" to an adjective doesn't always create an adverb (e.g., *daily*, *weekly*).
