Adjective or Adverb? - Easy

An adjective describes a noun or pronoun, so it tells you what a person, place, thing, or idea is like. In "a careful driver", careful describes the noun driver. An adverb often describes a verb, so it tells you how something happens. In "she drives carefully", carefully describes the action drives. This easy exercise keeps the contrast clear by using common pairs such as quick/quickly, gentle/gently, and clear/clearly. When you are unsure, find the word being described first, then choose the form that fits that job.

Many regular adverbs are made by adding -ly to an adjective: slow becomes slowly, quick becomes quickly, and careful becomes carefully. That pattern is useful at A2 level because it helps you see when a word is describing an action. However, -ly is not a magic ending that works everywhere. If the word describes a noun, keep the adjective: "a slow runner", not "a slowly runner". If it follows be and describes the subject, keep the adjective too: "the children were quiet". The sentence meaning decides the form.

Yes. Adverbs can describe verbs, but they can also make adjectives stronger or more precise. In "extremely happy", extremely describes the adjective happy. In "really interesting", really describes interesting. These examples are different from "she sings beautifully", where the adverb describes the action. This is why the exercise includes sentences such as "She was extremely happy" and "This is a really interesting book." The useful question is still the same: what does this word describe? If it describes an adjective, an adverb is usually the right choice.
