Choose by the sentence meaning
The problem: I remember one opposite and use it for every meaning of a word.
Start with what the word means here. For a difficult task, pair hard with easy. For a firm surface, pair hard with soft. Neither pair works for every use of hard.
| Opposite pair | Meaning to compare | Example |
|---|---|---|
| light / heavy | Weight | The empty jar is light, but the full jar is heavy. |
| light / dark | Color | Use light blue for the wall and dark blue for the door. |
| hard / easy | Difficulty | The final puzzle was hard, but the first one was easy. |
| hard / soft | How a surface feels | The wooden seat is hard; this cushion is soft. |
| old / young | Age of a living thing | The old horse walks beside a young horse. |
| old / new | Age of an object | Our old printer broke, so we ordered a new one. |
| clear / cloudy | Clouds in the sky | We flew through a cloudy sky and landed under a clear one. |
| clear / confusing | How easy something is to understand | Your map is clear, but mine is confusing. |
| hot / cold | Temperature | He added cold milk to his hot coffee. |
| warm / cool | Milder temperature differences | The kitchen feels warm, but the hall feels cool. |
| borrow / lend | Receiving or giving a temporary loan | I'll lend you my umbrella if you need to borrow one. |
| pass / fail | Meeting the required test score | You pass this test with ten points and fail with fewer. |
| locked / unlocked | Whether the lock prevents opening | The cabinet was locked at noon and unlocked by one. |
| open / closed | The state of a business | The bakery is open on Fridays and closed on Sundays. |
| success / failure | Whether an event achieves its aim | The first event was a success; the second was a failure. |
| arrive / leave | Reaching or going away from a place | I arrive before nine and leave after five. |
Some pairs describe the same event from two sides. A borrower receives something for a time; a lender gives it with an expected return. Changing borrow to lend also changes the person whose action you describe.

I bought an old car.
Answer: New
Show the answer
Answer: New
New fits the age of the car. Young can describe a living thing, such as a horse or a tree.
Say antonym and connect the pair
The problem: I miss the short word and when two opposites are spoken together.
Say antonym with the first part strongest: AN-tuh-nim. It has three syllables (sound beats). The middle vowel is short and weak. Keep the final m; the word does not end with n.
In pairs, and often has a weak sound when it is not emphasized. The surrounding words can run together. You do not need a pause after each word, but you still write and in full.
-
The boxes come in black and white.
Why it works: And may be weak between the two color words.
-
We sell both large and small notebooks.
Why it works: Large and small carry the contrast; and connects them.
Your turn
When it is not emphasized, how is and often said in up and down?
Answer: Briefly, with a weak sound
Show the answer
Answer: Briefly, with a weak sound
And often has a weak form between the main words. Its exact sound depends on the speaker and emphasis.
Keep the form that fits
The problem: I choose a related noun when the sentence needs an adjective.
When you replace a word, check the grammar around it. Safe and dangerous are adjectives: they describe something. Danger is a noun. It cannot fill the same space in the bridge sentence below.
-
Not this:
The bridge looks danger.Say: The bridge looks dangerous.
After looks here, use an adjective describing the bridge.
-
Not this:
His muscles are strong, but mine are weakness.Say: His muscles are strong, but mine are weak.
Use weak to describe the muscles. Weakness names the quality.
You can make noun pairs too. Strength pairs with weakness; success pairs with failure. Keep the form of a verb suitable for its time. The past of borrow is borrowed, while the past of lend is lent.
-
The team's strength is its speed; its weakness is poor planning.
Why it works: Strength and weakness are nouns naming qualities.
-
The visitors arrived at two and left at four.
Why it works: Arrived and left are both past forms.
Your turn
Choose the adjective that expresses the opposite meaning.
This bridge is safe.
Answer: Dangerous
Show the answer
Answer: Dangerous
Dangerous describes the bridge, just as safe does. Danger is a noun; dangerously describes how something happens.
Check the prefix you need
The problem: I add un- to a word without checking whether people use that form.
A prefix is a group of letters added at the beginning. It can help form an opposite, but the choice depends on the word. Learn kind with unkind, possible with impossible, and agree with disagree.
-
It was kind of you to wait.
Why it works: Kind describes considerate behavior.
-
His remark was unkind.
Why it works: Unkind describes behavior that may hurt someone.
A familiar opposite may use a different word altogether. For the weight of a suitcase, choose light to contrast with heavy. A learner's dictionary can show you the usual form and its meaning.
Your turn
Choose the usual opposite of heavy when describing weight.
Answer: Light
Show the answer
Answer: Light
Light is the usual opposite for weight. Learn the pair heavy and light instead of inventing a prefix form.
Before you go
Question 1 of 2

His directions were clear.
Answer: Confusing
Show the answer
Answer: Confusing
Confusing fits directions that are hard to understand. Cloudy and dark do not express the intended meaning here.
Question 2 of 2 · One new sentence
You need to check the weight of your packed suitcase. Choose the question that asks about weight.
Answer: Is the suitcase light or heavy?
Show the answer
Answer: Is the suitcase light or heavy?
For packing and luggage weight, the natural opposite pair is light and heavy.
Remember this
Try an opposite in your own sentence. Read the result once for meaning and again for grammar. If you are unsure about a new prefix form, check a dictionary example.

Try the written questionsQuestions about "Antonyms: choose the opposite that fits the meaning"
Can one word have more than one antonym?
Yes. Choose the opposite for the particular meaning. Light can contrast with heavy for weight or dark for color. A list gives possible partners, but the surrounding words tell you which one fits.
This fabric is light, but that wool is heavy.
She chose a light green shirt and dark green trousers.
Does not hot mean cold?
No. A temperature can be between hot and cold. Warm or cool may fit better. Saying not hot only rules out hot; it does not tell you exactly how the drink feels. Check the intended degree before you replace a negative phrase with an antonym.
The bath is not hot; it is warm.
The juice is cold after a night in the fridge.
Why are borrow and lend treated as opposites?
They describe the same temporary loan from different sides. The borrower receives the item, while the lender gives it. Both expect it to be returned. When you switch the verb, you also need to check who the subject is.
Mina borrowed a camera from Sam.
Sam lent Mina a camera.
Can I make an antonym by adding un-?
Sometimes. The prefix un- forms pairs such as kind and unkind. Other words use a different prefix or a separate word. Learn the actual pair and check unfamiliar forms in a learner's dictionary. Similar spelling alone does not prove that two words are opposites.
It is possible to finish today.
It is impossible to finish in one minute.
How is an antonym different from a synonym?
A synonym has the same or a similar meaning in context. An antonym has an opposing meaning. Two words are not antonyms simply because they name different things. Some words have no usual opposite, so do not force a pair for every new noun.
The lane is narrow, but the road is wide.
The task was easy, or simple.
