The Difference between Adjectives and Adverbs
The Basic Rules: Adjectives
Adjectives modify nouns. To modify means to change in some way. By modifying, adjectives give more detail about the noun. For example:
- "I ate a meal." Meal is a noun. The reader does not know what kind of meal this is, leaving a lot of room open for interpretation.
- "I ate an enormous meal." Meal is a noun, and enormous is an adjective that modifies it. It tells us what kind of meal the person ate. By using adjectives, the writer gives the reader a better understanding of the noun.
Adjectives clarify the noun by answering one of the following different questions: "What kind?" or "Which?" or "How many?" For example:
- "The tall girl is riding her bike." Tall tells the reader which girl the writer is talking about.
- “Our old van needs to be replaced soon.” Old tells the reader what kind of van the writer is describing.
- "The tough professor gave us the final exam." Tough tells the reader what kind of professor we're talking about. Final tells the reader which exam.
- "Fifteen students passed the midterm exam; twelve students passed the final exam." Fifteen and twelve both tell the reader how many students; midterm and final both tell the reader which exam.
So, generally speaking, adjectives answer the following questions:
- What kind of?
- How many?
Some Other Rules for Adjectives
Most of the time, adjectives come before nouns. However, some adjectives actually come after the nouns they modify. These adjectives will most often follow a verb from this list:
- "The dog is black." Black is an adjective that modifies the noun dog, but it comes after the verb is. (Remember that "is" is a form of the verb "be.") What kind of dog is it? A black dog.
- "Brian seems sad." Sad describes the noun, Brian, not the verb, seems. Sad answers the question “which way does Brian seem?”
- "The milk smells rotten." What kind of smell does the milk have? A rotten one.
- "The speaker sounds hoarse." Hoarse answers the question “which way does the speaker sound?”
- “The ice-cream looks melted.” Here, melted does not describe the verb looks. It describes the noun ice cream. What kind of ice cream does it look like? Melted ice cream.
- “Alex feels sleepy.” What kind of way does Alex feel? Sleepy.
The Basic Rules: Adverbs
Adverbs modify verbs, adjectives, and other adverbs. (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 modifies sang. It tells the reader how she sang.
- "The cellist played carelessly." Carelessly is an adverb that modifies played. It tells the reader how the cellist played.
Adverbs also modify adjectives and other adverbs.
- "That woman is extremely nice." Nice is an adjective that modifies the noun woman. Extremely is an adverb that modifies 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 modifies the noun afternoon. Terribly is an adverb that modifies the adjective hot. How hot is it? Terribly hot.
Adverbs answer the question how. They can also answer the questions when, where, and why.
- “She arrived late.” Late describes when she arrived.
- “They all went there for the party.” There is where they all went to the party.
- “The swim team practices every morning to develop good habits.” To develop good habits acts as an adverbial infinitive phrase that explains why the swim team practices every morning. Answering the question why usually requires an infinitive phrase.
In general, adverbs answer the following questions:
Examples of Differences between Adjectives and Adverbs
Be sure to note the differences between the following examples:
"The dog smells clean." Here, clean describes the dog itself. It's not that he smells something clean; it's that he's had a bath and does not stink. Clean describes what kind of smell comes from the dog making it an adjective.
"The dog smells carefully." Here, carefully describes how the dog smells, making it an adverb. We imagine him sniffing cautiously.
“Kai dressed for the quick recital.” Here, quick describes the noun, recital, making it an adjective. What kind of recital? A quick one.
“Kai dressed quickly for the recital.” Quickly describes the way Kai dressed, making it an adverb because it modifies the verb dressed. How did Kai dress? Quickly.
“Look at the nice bed.” Nice modifies the noun, bed, in this sentence, making it an adjective.
“Look at the nicely made bed.” Nicely modifies the adjective, made, in this sentence, making it an adverb.
“Joseph seems strange and upset.” Strange and upset modify the proper noun, Joseph, in this sentence, so strange and upset are both adjectives.
“Joseph seems strangely upset.” Strangely modifies the adjective, upset, in this sentence, so strangely is an adverb.
In general, when a word has the ending “-ly,” it will act as an adverb. Pay close attention to how the noun is modified, as this is the final criteria when deciding between an adjective and adverb.
Avoiding Common Errors
- Bad or Badly?
When you want to describe how you feel, you should use an adjective So you'd say, "I feel bad." Saying "I feel badly" would be like saying you play football badly. "I feel badly" would mean that you are unable to feel, as though your hands were numb. Here are some other examples:
- "The dog smells badly." Here, badly means that the dog does not do a good job of smelling.
- "The dog smells bad." Here, "bad" means that dog needs a bath.
N.B. Sometimes people say "I feel badly" when they feel that they have done something wrong. Let's say you dropped your friend's favorite dish, and it broke into a million pieces. You might say, "I feel really badly about what happened."
- Good or Well?
Good is an adjective, so you do not do good or live good, but you do well and live well. Remember, though, that an adjective follows sense-verbs and be-verbs, so you also feel good, look good, smell good, are good, have been good, etc. So:
"My mother looks good." This does not mean that she has good eyesight; it means that she appears healthy.
"I feel really good today." Again, this does not mean that I touch things successfully. It means rather that I am happy or healthy.
N.B. Many people confuse this distinction in conversation, and that's okay. You will hear people say, "I feel well" when they mean that they feel good. However, if you're talking about action verbs, you'd say "well." "I did well on my exam." "She plays tennis well."
- Sure or Surely?
Sure is an adjective, and surely is an adverb. For example:
- "He is sure about his answer." Sure describes he.
- "The Senator spoke out surely." Here, surely describes how the senator spoke.
N.B. Surely can also be used as a sentence-adverb. For example, "Surely, you're joking." Here, surely describes the entire sentence "you're joking." The sentence more or less means, "You must be joking."
- Near or Nearly?
Near can function as a verb, adverb, adjective, or preposition. Nearly is used as an adverb to mean "in a close manner" or "almost but not quite." Here are some examples that demonstrate the differences between various uses of near and nearly.
- "I'll be seeing you in the near future." Here, near describes the noun "future."
- "The cat crept near." Near is an adverb that describes where the cat crept.
- "Don't worry; we're nearly there." Here, nearly describes how close we are.
Near can also be used as a verb and a preposition.
- "My graduation neared." Here, neared is the verb of the sentence.
- "I want the couch near the window." Near is a preposition at the head of the phrase "near the window."
