What is the difference between and adjective and an adverb?

Adjectives give more detail about the thing you're describing (the noun). Normally, adjectives answer the following questions:-Which? (The messy bedroom)-What kind of? (A young, playful puppy)-How many? (Twelve apples)Adverbs give more detail about the way things are being done, they describe actions, or things, and sometimes even adjectives! (You can recognize adverbs easily because many of them are formed by adding -ly to an adjective, though that is not always the case.) The most common question that adverbs answer is how.Let's look at verbs first.-"She sang beautifully."  Beautifully is an adverb that describes sang. It tells the reader how she sang."The footballer played carelessly."  Carelessly is an adverb that describes played. It tells the reader how the footballer played.Adverbs also describe adjectives and other adverbs.-"That woman is extremely nice."  Nice is an adjective that describes the noun woman.  Extremely is an adverb that describes nice; it tells the reader how nice she is.  How nice is she? She's extremely nice.-"It was a terribly hot afternoon."  Hot is an adjective that describes the noun afternoon. Terribly is an adverb that describes the adjective hot.  How hot is it? Terribly hot.
