Word Knowledge, without memorising a list

The standard advice for Word Knowledge is to memorise a list of a few hundred words that "commonly appear". Everybody who has tried it knows how it goes: three weeks of flashcards, and on the day the words in front of you are not the words you learned.

The problem is arithmetic. English has a very large working vocabulary, and any list short enough to memorise covers a small fraction of what could be asked. You are betting a month of study on a narrow overlap.

The alternative is not learning more words. It is getting better at the words you do not know, which is a different skill and a much smaller one to acquire.

Most long English words are assembled from a fairly small stock of pieces, and the pieces recur constantly. Learning thirty of them gives you partial access to thousands of words, which is a far better return than thirty whole words.

Negation is the highest-value group. un-, in-, im-, ir-, il-, dis-, non-, a-. Spotting one of these tells you the word means roughly the opposite of the rest of it, and on a four-option question that alone often eliminates two.

Direction and position next. pre- and post- (before, after), sub- and super- (under, over), inter- (between), trans- (across), circum- (around), ex- (out), re- (again or back).

Then quantity. mono-, uni-, bi-, tri-, multi-, omni-, poly-, semi-, micro-, macro-.

And a handful of roots that pay repeatedly. -dict- (say), -spec- (look), -port- (carry), -duc- (lead), -scrib- (write), -ject- (throw), -vert- (turn), -ten- (hold), -mit- (send), -cred- (believe).

That is about forty pieces. Learned properly they are worth more than three hundred memorised words, and unlike a word list they keep working on vocabulary you meet for the rest of your life.

A repeatable order, worth practising until it is automatic.

One: break it apart. Prefix, root, ending. Incredulous is in- plus cred plus an ending — not believing. You have not defined it precisely and you do not need to; you need enough to sort four options.

Two: decide the charge. Even with no idea of the meaning, most words carry an obvious positive or negative feel, and it comes partly from the sound and partly from where you have heard it before. Getting the charge right eliminates the options with the wrong sign, which is frequently half of them.

Three: put it in a sentence you have heard. Not a definition — a phrase. People say "a candid conversation". Whatever candid means, it is the kind of thing a conversation can be, and it is not hostile. That is usually enough.

Four: eliminate rather than select. The question is not "which of these is the definition" but "which three of these are wrong". Those are different searches and the second one is easier, because a wrong option only has to be wrong in one respect.

Wrong options in a vocabulary question are not random, and two kinds account for most of the errors people make.

The lookalike. An option that resembles the word rather than means it — similar sound, shared prefix, same rhythm. It is there for the candidate who is pattern matching on shape. If an option looks like the word, that is a reason for suspicion rather than confidence.

The right idea, wrong strength. The word means "mildly annoyed" and the option says "enraged". Same direction, wrong intensity. This one catches people who have correctly worked out the charge and stopped there — which is why the charge is step two and not the last step.

Where a word appears in a sentence rather than alone, the sentence is not decoration. It usually contains the constraint that separates two otherwise plausible options, and it is commonly skimmed past by candidates in a hurry.

Read something with hard words in it, daily, briefly. Not a textbook. Anything written for adults who are not being talked down to — long-form journalism works well. Ten minutes is enough. The point is repeated exposure to words in context, which is how vocabulary is actually acquired and always has been.

Keep a list of words you met, not words someone gave you. A word you ran into and had to work out is attached to a context, and context is what makes it stick. Five a day from your own reading beats fifty from a list.

Practise the process, not the answers. When you work a practice question, say out loud which piece you recognised and which options you eliminated. It is slower and it is the part that transfers — the answer to that specific question is worth nothing.

The Word Knowledge questions here are original items written for this site, and each one shows its explanation after you answer. Use the explanation for how the wrong options were built, not for the definition.

Word Knowledge is one of the subtests feeding the composite most people are watching, and it is the one that responds fastest to the right kind of practice — it is a decoding skill, and decoding improves quickly.

The same reading habit does double duty on Paragraph Comprehension, which is the other verbal subtest and rewards exactly the same daily ten minutes. How the scores are put together covers which subtests feed what.
