Synonyms & Antonyms

Welcome to your first Verbal Reasoning lesson! In this lesson, you will learn about synonyms and antonyms — two of the most important word skills you will need for the GL 11+ exam. Understanding these will help you in many other question types too.

What Is a Synonym?

A synonym is a word that has the same or very similar meaning as another word.

Word	Synonym
happy	joyful
big	large
quick	fast
brave	courageous
begin	start
angry	furious
calm	peaceful
clever	intelligent

Top tip: Two words do not need to mean exactly the same thing — they just need to be very close in meaning.

What Is an Antonym?

An antonym is a word that means the opposite of another word.

Word	Antonym
happy	sad
big	small
quick	slow
brave	cowardly
begin	end
hot	cold
dark	light
generous	selfish

Why Do Synonyms and Antonyms Matter?

In the GL 11+ exam, you might be asked to:

Pick the word closest in meaning to a given word (synonym question).
Pick the word most opposite in meaning to a given word (antonym question).
Find the pair of words that are synonyms or antonyms from a list of five words.

These skills also help you with cloze passages, odd one out, and word analogy questions.

Worked Example 1: Synonym Question

Question: Select the word that is closest in meaning to enormous.

A) tiny B) average C) huge D) narrow

Step-by-step:

Read the target word: enormous — this means very, very big.
Look at each option:
- A) tiny — this means very small. That is the opposite!
- B) average — this means normal-sized. Not close enough.
- C) huge — this means very big. That matches!
- D) narrow — this describes width, not size in general.
Answer: C) huge

Worked Example 2: Antonym Question

Question: Select the word that is most opposite in meaning to generous.

A) kind B) wealthy C) mean D) gentle

Step-by-step:

Read the target word: generous — this means willing to give and share.
Look at each option:
- A) kind — this is similar to generous, not opposite.
- B) wealthy — being rich is not the opposite of being generous.
- C) mean — this means unwilling to share. That is the opposite!
- D) gentle — this is about being soft or careful, not about giving.
Answer: C) mean

Worked Example 3: Finding a Synonym Pair

Question: Find the two words that are closest in meaning.

ancient modern historic fresh young

Step-by-step:

Think about what each word means:
- ancient = very old
- modern = new, up-to-date
- historic = from the past, old and important
- fresh = new, recently made
- young = not old
Which two are closest? ancient and historic — both mean something old.
Answer: ancient and historic

Worked Example 4: Finding an Antonym Pair

Question: Find the two words that are most opposite in meaning.

expand explode contract extend grow

Step-by-step:

Think about what each word means:
- expand = get bigger
- explode = burst apart
- contract = get smaller
- extend = make longer
- grow = get bigger
Which two are most opposite? expand (get bigger) and contract (get smaller).
Answer: expand and contract

Building Your Vocabulary: Common Synonym Groups

Here are some useful groups of words with similar meanings. Try to learn them:

Words meaning "happy"

cheerful, delighted, pleased, joyful, content, glad, thrilled, ecstatic

Words meaning "sad"

miserable, unhappy, sorrowful, gloomy, downcast, dejected, melancholy

Words meaning "big"

enormous, huge, vast, immense, gigantic, colossal, massive

Words meaning "small"

tiny, minute, miniature, petite, microscopic, slight

Words meaning "brave"

courageous, fearless, bold, daring, heroic, valiant, gallant

Words meaning "scared"

frightened, terrified, alarmed, anxious, petrified, fearful

Building Your Vocabulary: Common Antonym Pairs

Word	Antonym
accept	refuse
ancient	modern
artificial	natural
attack	defend
capture	release
create	destroy
visible	invisible
victory	defeat
temporary	permanent
increase	decrease
include	exclude
flexible	rigid

Common Traps to Avoid

Trap 1: Words that look similar but mean different things

Do not confuse:

accept (to receive) and except (to leave out)
affect (to change) and effect (the result)
compliment (praise) and complement (go well with)

Trap 2: Words with multiple meanings

The word light can mean:

Not heavy (antonym: heavy)
Not dark (antonym: dark)
To set on fire (synonym: ignite)

Always read the sentence carefully to work out which meaning is being used.

Trap 3: Picking a word that is related but not a synonym

If asked for a synonym of hot, you might see options like summer or fire. These are related to hot, but they do not mean the same as hot. The correct answer would be something like boiling or scorching.

Prefixes That Create Antonyms

You can often make an antonym by adding a prefix to the beginning of a word:

Prefix	Example	Meaning
un-	unhappy	not happy
dis-	disagree	not agree
im-	impossible	not possible
in-	invisible	not visible
ir-	irregular	not regular
il-	illegal	not legal
mis-	misunderstand	understand wrongly
non-	non-fiction	not fiction

Top tip: If you are stuck on an antonym question, check whether adding a prefix to one of the options gives you the target word — or vice versa!

Practice Strategy

Read widely — the more books you read, the more words you will know.
Use a thesaurus — when you learn a new word, look up its synonyms and antonyms.
Make flashcards — write the word on one side and its synonym/antonym on the other.
Play word games — games like Scrabble and crosswords build vocabulary.
Practise under timed conditions — in the real exam, you will need to be quick!
