Usage Note

Example

Common collocations

Antonyms

Grammar Patterns

Usage Note

Used almost exclusively of a person's character or company, not of their appearance. 'He is fun' means you enjoy his company, not that he looks amusing.

Synonyms

Antonyms

boredom
the lack of interest or enjoyment
misery
a state of great unhappiness

Grammar Patterns

have fun

Usage Note

Fun as a noun is uncountable, so it is never used with 'a' (❌ a fun) and has no plural form. Use 'a lot of fun' or 'so much fun' instead.

Common Mistakes

We had a fun at the park.

We had fun at the park.

'fun' is uncountable; do not use 'a' before it.

2.nounA2

Example

Selim started learning Cantonese just for fun, not because he needed it for work.

for fun — purpose phrase

We built the treehouse purely for fun — it is not meant to be used as a real room.

Common collocations

for fun
just for fun
purely for fun
a bit of fun
all in fun

Synonyms

recreation
more formal; refers to activities done to relax
leisure
refers to free time rather than the purpose of an action

Antonyms

serious, effortful activity with a practical goal
business
activity done for professional or practical reasons

Grammar Patterns

for fun

just for fun

purely for fun

Usage Note

This sense is most common in the fixed phrases 'for fun' and 'a bit of fun'. Unlike noun sense 1, it emphasises the purpose rather than the feeling.

Common Mistakes

'fun' has no plural form even in this phrase.

3.nounB1

Definition

If you make fun of someone or something, you say unkind or mocking things about them in order to amuse others at that person's expense, often causing embarrassment or hurt.

Example

make fun of + person — core pattern

Common collocations

make fun of
poke fun at

Synonyms

mockery
more formal; implies contempt or scorn, not just teasing
ridicule
stronger, suggesting intention to make someone seem foolish
teasing
can be gentler; not always unkind

Antonyms

praise
expressing approval rather than criticism
respect
treating someone with dignity rather than mockery

Grammar Patterns

make fun of + noun phrase

Usage Note

This sense almost always appears in the fixed phrase 'make fun of'. The noun cannot be used freely outside this construction — you cannot say 'fun was directed at him.'

Common Mistakes

They had fun of him.

They made fun of him.

the correct form is 'make fun of', never 'have fun of'.

4.nounA2

Definition

Fun describes light-hearted joking and silly behaviour where nothing has a serious purpose and the goal is simply amusement.

Example

There is always a lot of fun and laughter whenever the cousins visit.

The meeting began with some fun — a quick trivia game to wake everyone up.

Common collocations

full of fun
fun and laughter
fun and games

Synonyms

playfulness
more formal; describes the quality of being light-hearted
mischief
suggests slightly naughty or cheeky behaviour
joking
focuses on verbal humour rather than general behaviour

Antonyms

seriousness
the quality of being earnest or solemn

Grammar Patterns

full of fun

all in fun

Usage Note

This sense overlaps with noun sense 1 but emphasises the playful, unserious nature of the activity rather than the feeling it produces. Often appears with 'and laughter' or 'and games'.

5.nounB1

Definition

If you say or do something in fun, your purpose is to make people laugh, not to cause harm — even if someone might feel upset or offended by it.

Example

Gabriela called her brother a clumsy giant, but she said it only in fun.

in fun — signalling a joke despite the words

I know that comment sounded harsh, but I promise I meant it in fun.

Common collocations

in fun
said in fun
meant in fun
done in fun

Synonyms

in jest
more formal or old-fashioned; means the same as 'in fun'
as a joke
more literal; emphasises the humorous intention

Antonyms

seriously, not as a joke
with malice
with the intention to hurt

Grammar Patterns

in fun

said in fun

meant in fun

Usage Note

The phrase 'in fun' typically appears after verbs like 'say', 'do', or 'mean'. It is used to reassure someone that no harm was intended. Distinguish from noun sense 3 (mockery): 'in fun' is harmless joking, whereas 'make fun of' is unkind.

Common Mistakes

I said it on fun.

I said it in fun.

the correct preposition is 'in', not 'on'.

Synonym discussion

Sense: noun/1

All five words describe positive experiences, but they differ in scope and focus. Fun is the most general and informal — it covers the happy feeling you get from any light-hearted activity ('We had fun at the beach'). Enjoyment is slightly more formal and emphasises the active, conscious experience of liking something ('She takes great enjoyment in reading'). Pleasure is broader still, covering satisfaction, delight, and even physical comfort ('It gave me pleasure to help'), but it can sound more serious or formal than fun. Amusement focuses on entertainment that makes you smile or laugh — passive rather than active — and is often used for comedy, games, or distractions ('Much to everyone's amusement, the cat climbed the curtain'). Entertainment refers specifically to events, shows, or media designed to hold your interest ('The film provided two hours of entertainment'). Choose fun for everyday, casual contexts; enjoyment and pleasure for more reflective or formal writing; amusement when laughter or smiles are central; and entertainment when discussing organised activities or media.

Etymology

Old EnglishMiddle EnglishModern English

The word fun comes from an old English verb fonnen, meaning 'to fool around' or 'to be foolish'. In the 1600s, fun was a noun meaning 'a cheat or trick', and by the early 1700s it had softened to mean 'diversion, amusement'. The adjective use (a fun party) only became common in the mid-1900s, and the verb form (funning around) has existed since the 1600s but is now very informal and rare.
