Grammar Lessons for Teachers: Comparative and superlative adjectives (2024)

Introduction

One way to describe a person or thing is by saying they have more of a particular quality than someone or something else. To do this, we use comparative adjectives, which are formed either by adding-er at the end of the adjective or placing more before it, for example:

• This piece of cake is bigger than that one.
• She is more intelligent than her sister.

It is also possible to describe someone or something by saying they have more of a particular quality than any other. We do this by using superlative adjectives, formed by adding the article the before the adjective and-est at the end or adding the most before the adjective. For example:

• This is the biggest piece of cake.
• She isthe most intelligent woman I’ve ever met.

Some rulesabout forming comparatives and superlatives

Comparatives

1. One-syllable adjectives generally form the comparative by adding -erat the end of the adjective. Some things you need to consider:

1. If a one-syllable adjective ends with a consonant-vowel-consonant combination, the second vowel must be doubled before adding

   -er (e.g., thin-thinner, big-bigger).

2. If the one-syllable adjective ends in a silent -e, only -r should be added at the end of the adjective, instead of -er (e.g., nice-nicer, wide-wider).

2. We add the word more before the adjectivewhen it has more than one syllable or to compare two different adjectives:

• The icing was supposed to be pink and white, but it looked more red than pink.
• That sofa might look nice, but this one is more comfortable.

3.If the adjective ends in a consonant followed by-ythe-yis replaced by an-ibefore adding-er (e.g., sunny- sunnier, happy- happier).

Use of comparatives

• Just like other adjectives, comparatives can be placed before nouns in the attributive position (e.g.,a more intelligent child,a bigger piece of cake).
• Comparatives can also occur after the verb to be and other linking verbs. Examples:
  • The street has become quieter since they left.
  • You should be more sensible.
• Comparatives are very commonly followed by than and noun, noun phrase, pronoun, or another clause to describe who the other person or thing involved in the comparison is:
  • John is taller thanme.
  • I think that she’s more intelligent thanher sister.
  • I think the portions were bigger thanthey were last time.
  • They gavea better performance thanin previous years.
• Comparatives are often qualified by using words and phrases such asmuch,a lot,far,a bit/little,slightly, etc.:
  • You should go by train, it would be much cheaper.
  • Could you be a bit quieter?
  • I’m feeling a lot better.
  • Do you have one that’s slightly bigger?
• Two comparatives can be contrasted by placing the before them, indicating that a change in one quality is linked to a change in another:
  • The smaller the gift, the easier it is to send.
  • The more stressed you are, the worse it is for your health.
• Two comparatives can also be linked withandto show a continuing increase in a particular quality:
  • The sea was getting rougher and rougher.
  • Her illness was becoming worse and worse.
  • He became more and more tired as the weeks went by.

Superlatives

1. One-syllable adjectives generally form the superlative by adding the before the adjective and-estat the end of the adjective. Some things you need to consider:

1. If a one-syllable adjective ends with a consonant-vowel-consonant combination, the second vowel must be doubled before adding-est (e.g.,thin - the thinnest,big- the biggest).
2. If the one-syllable adjective ends in a silent-e, only-stshould be added at the end of the adjective, instead of-est(e.g.,nice - the nicest, wide- the widest).

2. We add the most before the adjective when it has more than one syllable:

• That is the most beautiful dress I've seen.
• That sofa is the most comfortable in the store.

3.If the adjective ends in a consonant followed by-ythe-yis replaced by an-ibefore adding-est(e.g., sunny - thesunniest, happy - thehappiest).

Use of superlatives

• Like comparatives, superlatives can be placed before nouns in the attributive position, or occur afterbeand other link verbs:
  • It is the most delicious chocolate cake I’ve ever eaten.
  • Annabel was the youngest.
  • This restaurant is the best.
• As shown in the second two examples, superlatives are often used on their own if it is clear what or who is being compared. If you want to be specific about what you are comparing, you can do this with a noun or a phrase beginning with in or of:
  • Annabel was the youngest child.
  • Annabel was the youngest of the children.
  • This restaurant is the best in town.
• Another way of being specific is by placing a relative clause after the superlative:
  • This offer is the best I’m going to get.
• Note that if the superlative occurs before the noun, in the attributive position, theinorofphraseor relative clause comes after the noun:
  • The bestrestaurant in town.
  • The best offer I’m going to get.
• Althoughtheusually occurs before a superlative, it is sometimes left out in informal speech or writing:
  • This one seems to be cheapest.
• However,thecannot be left out when the superlative is followed by anof/inphrase, or a relative clause indicating the group of people or things being compared:
  • This one is the cheapest.
  • This one is cheapest.
  • This one is the cheapest of the new designs.This one is cheapest of the new designs.
  • This one is the cheapest I could find. This one is cheapest I could find.
• Sometimes possessive pronouns are used instead ofthebefore a superlative:
  • my youngest brother
  • her most valuable piece of jewellery
• Ordinal numbers are often used with superlatives to indicate that something has more of a particular quality than most others of its kind:
  • It’s the third largest city in the country.
  • The cathedral is the second most popular tourist attraction.
• In informal conversation, superlatives are often used instead of comparatives when comparing two things. For example, when comparing a train journey and a car journey to Edinburgh, someone might say:the train is quickest, rather than:the train is quicker. Superlatives are not generally used in this way in formal speech and writing.

Other things to consider when working with comparatives and superlatives

• Two-syllable adjectives ending in-ed,-ing,-ful, or-lessalways form the comparative withmoreand the superlative withmost.

• As a general rule, most other two-syllable adjectives also form comparatives and superlatives withmoreandmost, apart from those ending in-y(see point 3 above). However, a few two-syllable adjectives can take either-er/-estormore/most. Here are three examples.

• The only exceptions are some three-syllable adjectives which have been formed by adding the prefixun-to another adjective, especially those formed from an adjective ending in-y. These adjectives can form comparatives and superlatives by usingmore/mostor adding-er/-est.

• The following adjectives have irregular comparative and superlative forms:

• The adjectives ill andwell, describing bad and good health, have irregular comparative forms. The comparative of ill is worse, and the comparative of well is better, (e.g. She’s feeling much better/worse today).
• The usual comparative and superlative forms of the adjective old are older and oldest. However, the alternative forms elder and eldest are sometimes used. Elder and eldest are generally restricted to talking about the age of people, especially people within the same family, and are not used to talk about the age of things:
  • It’s the oldest eldest castle in Britain.
• Elder cannot occur in the predicative position after link verbs such as be, become, get, e.g.:
  • We’re all getting older elder.
  • My brother is older elder than me.
• Comparatives and superlatives of compound adjectives are generally formed by using more andmost:
  • Going skiing was the most nerve-wracking experience I’ve had.
• Some compound adjectives have a first element consisting of an adjective which would normally form a comparative or superlative in one word, either by adding-er/-est, or by an irregular form. Such compound adjectives can, therefore form a comparative/superlative by using these changes to the first adjective, rather than by usingmore/most.

• Some adjectives which already have a comparative or superlative meaning do not usually occur with -er/-est or more/most, unless we want to give special emphasis, often for humorous effect Common examples of adjectives like these are:complete,equal,favourite, andperfect.:
  • Mussels are my most favourite food.

The opposite of comparative and superlative forms

• Comparative and superlative forms with -er/-est and more/most are always used to talk about a quality which is greater in amount relative to others. If we want to talk about a quality which is smaller in amount relative to others, we use the forms less (the opposite of comparative more) and the least (the opposite of superlative the most). Less is used to indicate that something or someone does not have as much of a particular quality as someone or something else:
  • This sofa is less comfortable.
  • I’ve always been less patient than my sister.
• The least is used to indicate that something or someone has less of a quality than any other person or thing of its kind:
  • It’s the least expensive way to travel.
  • She was the least intelligent of the three sisters.
