As we’ve learned, adjectives and adverbs act in similar but different roles. A lot of the time this difference can be seen in the structure of the words:
- A clever new idea.
- A cleverly developed idea.
Clever is an adjective, and cleverly is an adverb. This adjective + ly construction is a short-cut to identifying adverbs.
While –ly is helpful, it’s not a universal rule. Not all words that end in –ly are adverbs: lovely, costly, friendly, etc. Additionally, not all adverbs end in -ly: here, there, together, yesterday, aboard, very, almost, etc.
Some words can function both as an adjective and as and adverb:
- Fast is an adjective in “a fast car” (where it qualifies the noun car), but an adverb in “he drove fast” (where it modifies the verb drove).
- Likely is an adjective in “a likely outcome” (where it modifies the noun outcome), but an adverb in “we will likely go” (where it modifies the verb go).
Mistaking Adverbs and Adjectives
One common mistake with adjectives and adverbs is using one in the place of the other. For example:
- I wish I could write as neat as he can.
- The word should be neatly, an adverb, since it’s modifying a verb.
- Well, that’s real nice of you.
- Should be really, an adverb, since it’s modifying an adjective
Remember, if you’re modifying a noun or pronoun, you should use an adjective. If you’re modifying anything else, you should use an adverb.
Good v. Well
One of the most commonly confused adjective/adverb pairs is good versus well. There isn’t really a good way to remember this besides memorization. Good is an adjective. Well is an adverb. Let’s look at a couple of sentence where people often confuse these two:
- She plays basketball good.
- I’m doing good.
In the first sentence good is supposed to be modifying plays, a verb; therefore the use of good—an adjective—is incorrect. Plays should be modified by an adverb. The correct sentence would read “She plays basketball well.”
In the second sentence, good is supposed to be modifying doing, a verb. Once again, this means that well—an adverb—should be used instead: “I’m doing well.”
Select the correct modifier for each sentence. Identify whether each modifier is an adjective or an adjective. Type your sentences in the text frame below:
- Billy has to work (real / really) hard to be (healthy / healthily).
- Kate is really (good / well) with bows. She shoots really (good / well).
- Eli reads (quick / quickly), and he retains the information (good / well).
- Billy has to work really hard to be healthy.
- Really modifies the adjective hard.
- Remember that to be is a linking verb. Linking verbs often connect the subject of the sentence (Billy) to an adjective that describes it (healthy).
- Kate is really good with bows. She shoots really well.
- Good is an adjective. The linking verb good connects it to the noun Kate.
- Well is an adverb that modifies the verb shoots.
- Eli reads quickly, and he retains the information well.
- Quickly is an adverb that modifies the verb reads.
- Well is an adverb that modifies the verb retains.
