Ten words a day beats a hundred in one night

Words300
Sets of ten30
Weeks at one set a day, 5 days a week6

These are words of the kind Word Knowledge tests: formal, everyday-adult words like abate, laud or futile. Each one comes with what it means, its opposite, and a sentence that shows it used correctly.

Key idea

A word is learned when you can use it

Reading a meaning once is not enough. You know a word when you can give its meaning, its opposite and your own sentence without looking. That takes a few short visits on different days, which is why the list comes in sets.

The list, set by set

    Next step: Three examples
  7. 7

    Three worked examples, from easy to test level

    How to learn a word from the list, and how the test will try to trick you with it. Each starts with the guess most people make, crossed out.

    Example · Easy

    Laud most nearly means…

    First tryLaud sounds like “loud”, so it means noisy

    1. Do not trust the sound. Look it up in the list: laud means praise, and its opposite is criticize.
    2. Make your own sentence: “The sergeant lauded the squad for finishing early.”
    3. Tomorrow, cover the meaning and say it from memory before the next set.

    Answer praise

    Example · Medium

    Incredulous most nearly means…

    First tryIt looks like “incredible”, so it means amazing

    1. Break it into parts: in- means not, cred means believe.
    2. So incredulous is “not believing”: unwilling to believe.
    3. Incredible describes a thing that is hard to believe; incredulous describes a person who does not believe.

    Answer unwilling to believe

    Example · Test level

    “The note was so cryptic that no one knew what it asked for.” Cryptic most nearly means…

    First tryA crypt is a tomb, so cryptic means scary

    1. Use the sentence: no one knew what the note asked for. So the word is about being hard to understand.
    2. Put your own word in its place: “so puzzling that no one knew what it asked for” makes sense.
    3. The word part crypt means hidden, like a hidden meaning. Cryptic means puzzling and mysterious.

    Answer puzzling

Next: Watch out

4 traps in the answer choices

The test writes its wrong answers on purpose: each one is what you get if you make one of these mistakes.

Trap

The look-alike

Allude and elude look and sound alike:

Wrongallude = escape

Rightallude = hint at; elude = escape

Trap

The opposite choice

Futile most nearly means:

Wrongeffective (its opposite)

Rightuseless

Trap

The sound-alike

Council and counsel sound the same:

Wrongcouncil = advice

Rightcouncil = a group that advises or decides

Trap

The wrong prefix

“in-” does not always mean not. Innate:

Wronginnate = not natural

Rightinnate = inborn (in- = in)

Next: Practice

15 questions in three levels

Warm-up first, then core, then test level. Pick an answer, then read why.

On test day

On the computer test, Word Knowledge has 15 questions that count, in 9 minutes: about 36 seconds a word. On paper it is 35 questions in 11 minutes. There is no time to work a word out slowly: you either know it or you use a quick strategy.

That is why the list works best a little every day, starting in week 1 of your plan. The words you have seen several times are the ones you will recognize in 36 seconds.

Question 1 of 15 · Warm-up

Abate most nearly means:

Show the answer

B. Abate means to lessen or die down, like rain that abates. Intensify is its opposite, the trap. The answer is lessen.

Question 2 of 15 · Warm-up

Laud most nearly means:

Show the answer

A. Laud means to praise. “Shout” is the sound trap (laud sounds like loud), and blame is close to its opposite. The answer is praise.

Question 3 of 15 · Warm-up

Vast most nearly means:

Show the answer

A. A vast area is very large. Tiny is the opposite, and empty describes what is inside, not the size. The answer is huge.

Question 4 of 15 · Warm-up

Futile most nearly means:

Show the answer

D. A futile effort gets nothing done. Useful is the opposite choice the test plants for you. The answer is useless.

Question 5 of 15 · Warm-up

Expedite most nearly means:

Show the answer

C. To expedite an order is to make it go faster. Delay is the opposite, and export only looks similar. The answer is speed up.

Question 6 of 15 · Core

“The medic gave him ice to mitigate the swelling.” Mitigate most nearly means:

Show the answer

D. Ice is used to make swelling less severe. Replace the word: “ice to ease the swelling” makes sense. Worsen is the opposite. The answer is ease.

Question 7 of 15 · Core

“On his first day the new driver was taciturn, answering every question with one word.” Taciturn most nearly means:

Show the answer

C. The clue is “answering with one word”: he says very little. Talkative is the opposite, and rude adds a meaning the sentence does not give. The answer is quiet.

Question 8 of 15 · Core

“The kitchen had a stringent rule: no one enters without a hairnet.” Stringent most nearly means:

Show the answer

A. A rule with no exceptions is a strict rule. Unfair adds a judgment the sentence does not make. The answer is very strict.

Question 9 of 15 · Core

“The price difference between the two brands was negligible, only a few cents.” Negligible most nearly means:

Show the answer

C. A few cents is too little to care about. Careless is the trap: it is the meaning of the look-alike negligent (“a negligent driver”), not of negligible. The answer is too small to matter.

Question 10 of 15 · Core

“My cousin is gullible: he believes every ad he sees online.” Gullible most nearly means:

Show the answer

D. Believing every ad means anyone can trick him. Curious is a reason to read ads, not to believe them. The answer is easily fooled.

Question 11 of 15 · Test level

Ephemeral most nearly means:

Show the answer

B. Ephemeral means lasting only a short time, like a soap bubble. Lasting is its opposite: knowing the opposite helps you cross out the trap. A bubble is light, but the word is about how long something lasts, not its weight. Ephemeral most nearly means short-lived.

Question 12 of 15 · Test level

Garrulous most nearly means:

Show the answer

B. A garrulous person talks a lot, often about small things, like a passenger who chats for the whole flight. Quiet is its opposite, the trap the test plants. Hungry and angry have nothing to do with talking. Garrulous most nearly means talkative.

Question 13 of 15 · Test level

Deplete most nearly means:

Show the answer

C. To deplete a supply is to use it until little or nothing is left: “the long hike depleted our water.” Replenish is its opposite: to fill it again. Delete only looks similar: it means to erase. Delay means to make something late. Deplete most nearly means use up.

Question 14 of 15 · Test level

“She alluded to the problem in her speech but never named it.” Alluded most nearly means:

Show the answer

B. “Never named it” tells you she only mentioned it indirectly. Stated directly is the opposite, and escaped belongs to elude, the look-alike. The answer is hinted at.

Question 15 of 15 · Test level

“The new schedule had a clear effect on morale.” Effect most nearly means:

Show the answer

C. An effect is what comes out of something: the schedule changed morale. Cause is the opposite end of the chain. The answer is result.
