When you say something is good, you give basic information. When you say it is extremely good or rather good, you show exactly how good you mean. According to the Cambridge Grammar, intensifiers are words that come before adjectives or adverbs to make their meaning stronger or weaker. They are one of the most-used grammar tools in everyday English and are essential for sounding natural and precise at A2 and B1 level.
What Are Intensifiers?
An intensifier is a word — almost always an adverb — that changes the strength or degree of an adjective or adverb. Linguists divide intensifiers into two main groups:
- Amplifiers increase the strength of the adjective:
very cold,extremely tired,absolutely brilliant. - Downtoners reduce the strength of the adjective:
quite cold,fairly tired,rather slow.
Intensifiers nearly always appear directly before the adjective or adverb they modify. They cannot normally stand alone or follow the word they modify: The film was very good is correct; The film was good very is not.
Amplifiers: Making Meaning Stronger
Amplifiers push the meaning of an adjective or adverb above its base level. They range in strength from moderate (very) all the way to absolute (completely, absolutely).
| Intensifier | Strength | Example |
|---|---|---|
| very | moderate–high | The soup is very hot. |
| really | high (informal) | That exam was really difficult. |
| extremely | very high | She was extremely nervous before the interview. |
| terribly | very high (formal/informal) | I'm terribly sorry for the delay. |
| incredibly | very high (informal) | The view from the top is incredibly beautiful. |
| absolutely | maximum (with ungradable adj.) | The film was absolutely brilliant. |
| completely | total (with ungradable adj.) | I was completely exhausted. |
| totally | total (informal) | That idea is totally wrong. |
Register note: Very and really are neutral to informal. Extremely and terribly suit formal writing. Incredibly and totally are informal or spoken.
Downtoners: Making Meaning Weaker
Downtoners reduce the force of a description, indicating that something is below average or only partially true. They are gentler than amplifiers and add an important layer of politeness and softening in English.
| Intensifier | Meaning / nuance | Example |
|---|---|---|
| quite | to a noticeable degree (BrE: less than very; AmE: completely) | The food was quite good. |
| rather | to a surprising or unexpected degree; slightly more than expected | The test was rather hard. |
| fairly | to a reasonable, moderate degree | She speaks English fairly well. |
| pretty | moderate (informal) | That's a pretty good idea. |
| slightly | just a little; small amount | The room is slightly too cold. |
| a bit | small amount (informal) | Could you speak a bit more slowly? |
| a little | small amount (neutral) | I'm a little tired today. |
Gradable vs. Ungradable Adjectives
This is the rule most learners at B1 level need to understand. Adjectives split into two categories, and the intensifier you choose depends on which type you are using.
Gradable adjectives
A gradable adjective exists on a scale — there can be more or less of it. Use amplifiers like very, extremely, really and downtoners like quite, fairly, rather with these adjectives.
- cold → slightly cold / very cold / extremely cold
- tired → a little tired / very tired / incredibly tired
- interesting → quite interesting / really interesting / extremely interesting
Ungradable (absolute / extreme) adjectives
An ungradable adjective is already at the extreme end of a scale — it has no degrees. Words like freezing, exhausted, brilliant, terrible, enormous, impossible are already "total". You cannot say something is very freezing or very exhausted. Instead, use maximisers: absolutely, completely, totally, utterly.
absolutely freezing(notvery freezing)completely exhausted(notvery exhausted)absolutely brilliant(notvery brilliant)totally impossible(notvery impossible)
| Gradable (use very / quite) | Ungradable equivalent (use absolutely) |
|---|---|
| cold | freezing |
| hot | boiling / scorching |
| tired | exhausted |
| good | brilliant / excellent / perfect |
| bad | terrible / dreadful / awful |
| big | enormous / gigantic / huge |
| small | tiny / microscopic |
| funny | hilarious |
| surprised | astonished / amazed |
| dirty | filthy |
The Tricky Case of quite
The word quite causes more confusion than almost any other intensifier because it behaves differently depending on the type of adjective and the variety of English being spoken.
With gradable adjectives (British English)
In British English, quite is a downtoner meaning "to some degree but not very much": The hotel was quite comfortable (= fairly comfortable, but not exceptional). This is often a polite way of expressing mild disappointment.
With ungradable adjectives
With ungradable adjectives, quite changes meaning and acts as a maximiser equivalent to absolutely: That was quite brilliant (= absolutely brilliant). I'm quite sure means completely sure, not just "a bit sure".
American English
In American English, quite usually means "very" or "completely" with both gradable and ungradable adjectives: That's quite good (AmE: very good). Be aware of this difference when reading or listening to material from different English-speaking countries.
Position and Grammar Rules
Intensifiers are adverbs of degree. Their position in a sentence follows strict patterns:
- Before an adjective:
very tired,absolutely brilliant,quite interesting - Before an adverb:
He speaks very quickly./She runs incredibly fast. - Before a past participle used as an adjective:
completely surprised,rather bored - Not before nouns or verbs directly: You cannot say
a very ideaorshe veried smiled. Intensifiers need an adjective or adverb as their target.
One partial exception is quite a and rather a before a noun phrase with an adjective: It was quite a difficult exam. / That was rather a strange thing to say. Here quite / rather precede the article, and the adjective follows as normal.
Common Errors to Avoid
Even intermediate learners make predictable mistakes with intensifiers. Knowing these patterns in advance will help you avoid them:
- Using very with ungradable adjectives: Do not say very exhausted or very freezing. Use absolutely or completely instead.
- Confusing quite in British and American contexts: Quite good in British English is modest praise; in American English it is strong praise. Context and speaker background matter.
- Overusing very: In formal writing and at B1+, replace very with more precise amplifiers or with a stronger adjective. Instead of very big, try enormous. Instead of very tired, try exhausted.
- Mixing up fairly and rather: Both are downtoners, but rather often implies something unexpected or more negative: The film was rather long (= longer than I expected, and perhaps annoyingly so). Fairly long is more neutral.
- Placing the intensifier after the adjective: The film was good very is incorrect. Intensifiers always precede the word they modify.

Frequently Asked Questions
What is an intensifier in English grammar?
An intensifier is a word — almost always an adverb — that modifies an adjective or another adverb to show degree. Intensifiers either make the meaning stronger (amplifiers: very, extremely, absolutely) or weaker (downtoners: quite, fairly, slightly). They appear directly before the word they modify and are one of the most common grammatical features of everyday spoken and written English.
What is the difference between very and absolutely?
Very is used with gradable adjectives — adjectives that exist on a scale — to increase their degree: very cold, very tired, very interesting. Absolutely is used with ungradable (extreme or absolute) adjectives that already express the maximum of a quality: absolutely freezing, absolutely exhausted, absolutely brilliant. A common error is using very with ungradable adjectives: do not say very freezing or very exhausted.
Does quite mean the same as very?
No — and this is a frequent source of confusion. In British English, quite with a gradable adjective is a downtoner meaning "to a moderate degree, but not very much": The film was quite good (= fairly good, not exceptional). However, with ungradable adjectives, quite becomes a maximiser meaning "absolutely": I'm quite sure (= completely sure). In American English, quite generally means "very" with both adjective types. Always consider the speaker's variety of English.
What is the difference between rather and fairly?
Both rather and fairly are downtoners, but they carry different nuances. Fairly is more neutral and means "to a moderate, acceptable degree": The instructions are fairly clear. Rather often implies surprise or that the degree is unexpectedly high — frequently with a slight negative or critical tone: The exam was rather difficult (= more difficult than I expected). Rather can also be used with positive adjectives in British English to express pleasant surprise: The hotel was rather lovely.
Can I use very before all adjectives?
No. Very is only correct with gradable adjectives. Do not use very before ungradable (extreme/absolute) adjectives. Compare: very tired (correct — tired is gradable) vs. very exhausted (incorrect — exhausted is ungradable; use absolutely exhausted). Other examples to avoid: very freezing, very enormous, very hilarious, very impossible. Replace very with absolutely, completely, or utterly for these adjectives.
Where do intensifiers go in a sentence?
Intensifiers always come directly before the adjective or adverb they modify. For example: She is very tired (before predicate adjective), a very tired person (before attributive adjective), He runs extremely fast (before adverb). A special case: quite a and rather a come before the article in noun phrases: It was quite a long meeting. You cannot place an intensifier after the word it modifies.
What are some formal alternatives to very for writing?
In formal writing, academic essays, and IELTS Writing Task 2, overusing very is considered weak style. Stronger alternatives include: extremely (very high degree), exceptionally (unusually high), remarkably (worthy of note), particularly (especially), considerably (by a large amount), significantly (in a meaningful way), highly (used with certain adjectives: highly effective, highly unlikely). Using a more precise strong adjective often works even better: instead of very important, write crucial or vital.
Is really an intensifier?
Yes. Really functions as an informal amplifier with a similar meaning to very: really tired, really interesting, really fast. It is extremely common in spoken English and informal writing. In formal writing and exams, it is better to replace really with very, extremely, or a more precise adverb. Really can also function as an adverb of truth meaning "in reality" (Is that really true?), which is a different use from its role as an intensifier.
How do intensifiers help with IELTS Speaking?
IELTS Speaking is assessed on Lexical Resource and Grammatical Range. Using a variety of intensifiers — rather than repeating very — demonstrates both a wider vocabulary and grammatical awareness. For example, varying your language with remarkably, fairly, incredibly, rather and absolutely shows range. Additionally, correctly pairing intensifiers with the right adjective type (e.g., absolutely exhausted not very exhausted) demonstrates accurate grammar, which directly raises your score.
What is the difference between a bit and slightly?
Both a bit and slightly are downtoners expressing a small degree. The main difference is register. A bit is informal and very common in conversation: I'm a bit tired. Slightly is neutral to formal and suits written English and professional contexts: The results were slightly higher than expected. Both can be used with gradable adjectives. Neither is used with ungradable adjectives: avoid a bit exhausted or slightly impossible in formal contexts; use rather or quite instead.
