Grammar Explanation: Comparison
Gradable adjectives can be used to make comparisons. The rules for the production of comparative and superlative forms of adjectives are generally straightforward but there can be difficulties with spelling, exceptions in use, and the different phrases which accompany them. This unit also describes ways of making comparisons without using comparative and superlative forms, e.g. with like and as.
Comparative and Superlative Adjectives
Degree of comparison: Rules, Form and Use
|Hot Dog €1.50||Hamburger € 2.75|
|Fish Burger € 2.75||Cheeseburger € 3.95|
We use comparative adjectives to compare two (or more) things or people, and superlative adjectives to distinguish one thing or person from a number of others. This table shows the forms of comparative and superlative adjectives and the basic patterns they are used in:
|Comparative adjectives||Superlative adjectives|
|adjectives with one syllable:
ending in silent -e: safe
ending in a consonant + y: dry
ending in a single vowel +
a single consonant: big
|adjective + -er (+ than).
The hamburger is cheaper (than the cheeseburger).
The mop is wetter (than it was before)
He is duller ( than he was yesterday)
This velvet cloth is softer ( than other clothes)
This room is tidier (than it was before)
omit final -e: safer
change y to i: drier
double the final consonant:
|the + adjective + -est:
The hot dog is the cheapest
The is the wettest mop I’ve ever seen
He is the dullest in class.
The cloth is the softest in the store
This room is the tidiest
omit final -e: the safest
change y to i: the driest
double the final consonant:
|adjectives with two or more syllables:
|more + adjective:
||the most + adjective:
|the best/ worst
We can use than to introduce a clause after a comparative adjective:
- Los Angeles is bigger than I expected it to be
We can use other phrases between a comparative adjective and a than clause:
- Burgers were more expensive in this restaurant than in the others we visited.
Note: If the object of the comparison is a pronoun without a verb we usually use an object pronoun. If there is a verb we use a subject pronoun:
- I'[m taller than he.] ✓ I’m taller than him ✓ I’m taller than he is.
Note: When we have two or more adjectives with more in a list, we usually only use more once:
- [Lester and Craves were more hardworking and more determined than the others.]
✓ Lester and Graves were more hardworking and determined than the others.
When we refer to a place or group we use ‘in’ not ‘of’ after superlatives.
X New York is one of the largest cities of the world.
✓ ..in the world.
X He s by far the cleverest student of his class.
✓…in his class.
But in formal English we can put an ‘of’ phrase at the beginning of the sentence, before the superlative.
- Of the students in his class, he is the cleverest.
There are some exceptions to the rules of form and the patterns of use listed above. One-syllable adjectives ending in -ed and the adjectives real, right and wrong form the comparative and superlative with more and most (they do not take -er and -est):
X I was broader than I was on the flight to Sydney.
✓ I was more bored than I was on the flight to Sydney.
Many two-syllable adjectives ending in -ly. -y, -ow. -r and -l and the adjectives common, handsome, mature, pleasant, polite, simple and stupid can have either more and most or -er and -est:
- The photographer wanted something more lively (or livelier).
- Your son needs to develop a mature (or more mature) attitude to his work.
When we add a negative prefix to two-syllable adjectives ending in -y (e.g. happy -unhappy) they can still take -er and -est:
- He’s the unhappiest man in the world.
Note: In informal spoken English we sometimes use a superlative adjective when we are only comparing two things, especially if the two things make a set:
- I’ve got two cars but the Mercedes is the best
We can use elder and eldest (instead of older and oldest) to talk about people’s ages, especially people in the same family, but we can’t use elder immediately after a verb:
- Their eldest I oldest son went to Harvard. Mary is the eldest/the oldest.
X My sister is elder (than me). ✓ My sister is older (than me).
Note that we don’t use elder and eldest to talk about the age of things:
X This is the eldest house in the street. ✓ This is the oldest house in the street.
We use further or farther to talk about a ‘greater distance’:
- John’s house is the farther one.
- I’ve moved further away from my parents. (= a greater distance away)
Note: We use further (not farther) with the meaning of ‘extra’ or ‘more’:
- Let me know if you have any further questions. (= extra/more)
Emphasis and Strength
Most one-syllable adjectives can also form the comparative and superlative with more or most instead of -er or -est. We usually use this form for emphasis in spoken English:
- You should be more proud of the things you’ve already achieved. (= prouder)
- I think this is the one she is the most proud of. (= proudest)
Comparatives can be made stronger or weaker by inserting a word or phrase in front of them:
Stronger: even, (very) much, far, a lot, lots (informal), considerably, a great deal (formal) + comparative:
- The cheeseburger’s even more expensive than the fish burger.
Weaker: a little, slightly, a bit (informal), somewhat (formal) + comparative:
- The hot dog’s a bit cheaper than the hamburger.
We can make a superlative weaker or stronger in the same way.
Stronger: by far, easily (informal) + superlative:
- He’s by far the cleverest student in his class. (= He is much cleverer than the others.)
- She’s easily the best programmer in the company. (informal) (= She is much better than the others.)
Weaker: one of, some of + superlative:
- New York is one of the largest cities in the world. (= There may be some larger.)
To say that two things are equal we can use patterns like is + no + comparative or is not + any + comparative:
- The fish burger is no more expensive than the hamburger. (= They are the same price.)
- The fish burger isn’t any cheaper than the hamburger. (= They are the same price.)
Less and Least
We use less and least as the opposite of more and most. We use these words with all adjectives including one-syllable adjectives:
- I prefer the paisley pattern; it’s less bold than the others.
- The hot dog is the least expensive.
Note: But in informal English we usually prefer to make negative comparisons of this kind with not as …as:
- I prefer the paisley pattern; it isn’t as bold as the others.
Adjectives with As, So, Too, Enough and Such
We can say that two things are equal by using as + adjective + as.
- The hamburger is as expensive as the fish burger.
We make this comparison more emphatic with just:
- We really shouldn’t have gone; it’s just as bad as I predicted it would be!
To say that things are almost equal we use just about, about, almost or nearly.
- I’ve had just about as much as I can take.
- She’s nearly as old as I was when I got married.
We make a negative comparison with not as/ so + adjective + as.
- The hot dog isn’t as expensive as the hamburger. (= The hot dog is cheaper.)
We can modify this comparison with nearly or quite:
- The hot dog isn’t nearly so expensive as the cheeseburger. (= It is much cheaper.)
- The hot dog isn’t quite as expensive as the hamburger. (= It is slightly cheaper.)
In informal spoken English we can use not anything like, nothing like or nowhere near + as + adjective:
- The fish burger isn’t anything like as expensive as the cheeseburger.
- The fish burger’s nothing like (or nowhere near) as expensive as the cheeseburger.
So, too and enough
We use another type of ‘comparison’ when we describe the result of a particular quality or characteristic. We can use several structures:
so + adjective + [that] clause:
- I’m afraid I can’t identify her. It was so dark (that) I couldn’t see her face. (= It was very dark. The result was that I couldn’t see her face.)
too + adjective (+ for/to phrase):
- It was too dark (for me) (to see her face).
(not) adjective + enough (+ for/ to phrase):
- It wasn’t light enough (for me) (to see her face).
A more formal alternative to these forms is so + adjective + as to phrase:
- It was so dark as to make it impossible to see her face.
As and such
We can use as and such to introduce a comparison. There are two patterns:
as + adjective + a + noun + as:
- It wasn’t as bad a result as I’d expected. (= it was a better result than I’d expected.)
such a + adjective + noun + as (or that clause):
- It wasn’t such a bad result as I had expected.
- It was such a dark night that I couldn’t really see her face.
Other Types of Comparison
We can describe how something increases or decreases by repeating the same comparative two or sometimes three times, putting and between the forms:
- Her visits to the country to see her son became rarer and rarer (= increasingly rare)
- As the illness progressed the patients grew more and more detached from reality.
- Marching into the sunset, the figures became smaller and smaller and smaller
To describe how a change in one thing causes a change in another, we can use two comparative forms with the. Note the use of the comma after the first clause:
- The longer you leave it, the worse it’ll get.
We sometimes omit the verb be in the clauses:
- The more sophisticated the product, the more substantial the potential profit.
When we contrast two related qualities, we always use more (not -er):
X I ‘m sadder than disappointed.
✓ I’m more sad than disappointed.
- Her eyes are more green than grey.
We can also use not so much …as or rather than:
- I’m not so much disappointed as sad.
- Her eyes are green rather than grey.
Like and As
We often describe something by comparing it to something else which has similar qualities. These comparisons are known as ‘similes’. There are two forms:
as + adjective + as:
- Listening to her was about as interesting as watching paint dry.
(In informal English we sometimes omit the first as She looks white as a sheet.)
like + noun or verb phrase:
- The cruise ship was like a skyscraper lying on its side
There are many idioms in which we use these two patterns:
- You ‘re as white as a sheet: I think you’d better see a doctor.
- I feel full of energy today – I slept like a log last night.
Note: We use like (not as) before a noun when we are making a comparison between two things which seem similar:
X You look as a man who’s seen a ghost!
✓ You look like a man who’s seen a ghost!
- When Mike puts on his dark suit he looks like a waiter (= He resembles a waiter.)
Note: We use as (not like) before a noun when we are describing someone’s job, role or identity, or something’s function:
X Simon’s working like a waiter during the summer vacation.
✓ Simon’s working as a waiter during the summer vacation. (This is his job.)
- Use your payroll number as a password for the computer. (This is its function.)
Note: We can also describe something by comparing it with something similar without using like or as, this is known as a ‘metaphor’:
- We hope the new treaty will form a bridge between our two nations. (a bridge = metaphor for a link)
Metaphors are common in poetry and literary English:
- Sometimes too hot the eye of heaven shines. (eye of heaven = metaphor for the sun)

For this week’s consumer test we’ve been looking at the (0)__most__popular choices of competing hair conditioner. We chose the three (1)___selling brands: Supremesoft, Vitabalm and ActiveShine, and gave them to our panel of ordinary consumers to try for a month.
At $2.99 for 250ml Supremesoft is the (2)____expensive of the three brands. But, surprisingly, price is no guide to quality as this brand was (3)____more effective (4)____the cheaper brands. On the other hand, the panel felt the packaging was (5)_____upscale than the competitors, and the conditioner itself had an attractive color and scent. But these advantages weren’t significant (6)_____to compensate for the extra cost.
Vitabalm is the (7)_____of the tested brands ($1.99 for 250ml). Our consumers thought the packaging wasn’t (8)______attractive (9)_____the others and the conditioner had what one tester described as ‘a rather chemical smell’. It was (10)_____as effective as the others in dealing with tangled hair, but testers with dry hair found that it wasn’t rich enough (11)______give their hair any extra body. And everyone agreed that it was (12)____harsh to be useable on a daily basis.
This brand emerged as the (13)____all-round value for money. It had a strong smell, rather (14)_____an antiseptic cream, but the smell was not (15)_____strong as to be off-putting. Testers found that it was just as effective with greasy hair as with dry hair and it was (16)_____far the most successful with flyaway hair. ActiveShine doesn’t have (17)______a rich composition as Supremesoft, but our testers found that (18)_____more they used it, the (19)______noticeable the effect on their hair, so it was considered to be just as effective (20)_____the others in the long term.
So, at around $2.50 for 250ml ActiveShine receives this month’s three-star rating.
