R16: Unknown words: guess from context, don't panic

Every IELTS passage has words you don't know. Every single one, even for band 8 students. The difference is what you do next. Weaker students stop, panic, and lose time. Stronger students either ignore the word or guess its meaning from the sentence around it. This lesson teaches you how to do both.

Why this matters

You can't learn every English word before your test. There are too many. But you can learn to work out meaning quickly. That skill saves time and helps you answer questions even when the vocabulary is hard.

Step 1: Does this word matter?

Ask yourself: is this word in the part I need for a question? If not, skip it. Most unknown words don't matter. Don't waste energy on them.

Step 2: If it matters, use clues

Clue 1: A definition nearby. Writers often explain hard words right away.

"The animal is nocturnal, which means it is active mainly at night."

Clue 2: Examples. Words like such as and including give examples.

"The region is rich in minerals such as copper, iron and gold."

Clue 3: Contrast. Words like but, unlike and however show the opposite.

"Unlike his gregarious brother, Tom preferred to be alone."

So gregarious means the opposite of preferring to be alone. It means sociable.

Clue 4: Cause and effect.

"The crops failed because of the long drought."

What makes crops fail over a long time? A long period without rain.

Clue 5: Word parts.

Clue 6: Grammar. Is the word a noun, verb or adjective? Even without the meaning, knowing the type helps in completion questions.

Step 3: Good enough is good enough

You don't need the exact dictionary meaning. You need a rough idea: positive or negative? Big or small? A person or a thing? That's often enough to answer the question.

Try it yourself

Guess the meaning of the word in italics.

1. "The new drug proved highly efficacious. Almost all patients recovered within a week."
2. "The old factory was derelict, with broken windows and weeds growing through the floor."
3. "Unlike modern cities, which are carefully planned, medieval towns grew in a haphazard way."

1. Effective. (Most patients recovered.)
2. Abandoned and in bad condition. (Broken windows, weeds.)
3. Without a plan, random. (The opposite of carefully planned.)

Honest note

Context guessing isn't perfect. Sometimes you'll guess wrong. But a fast guess that's roughly right is better than a slow, perfect answer that costs you three other questions.
