Text: Functions of Adjectives

Figure holding a square in one hand and a triangle in the otherAn adjective modifies a noun; that is, it provides more detail about a noun. This can be anything from color to size to temperature to personality. Adjectives usually occur just before the nouns they modify. In the following examples, adjectives are in bold, while the nouns they modify are in italics (the big bear):

  • The generator is used to convert mechanical energy into electrical energy.
  • The steel pipes contain a protective sacrificial anode and are surrounded by packing material.

Adjectives can also follow a linking verb. In these instances, adjectives can modify pronouns as well. In the following examples, adjectives are still bold, while the linking verb is in italics this time (the sun is yellow):

  • The schoolhouse was red.
  • I looked good today.
  • She was funny.

Numbers can also be adjectives in some cases. When you say “Seven is my lucky number,” seven is a noun, but when you say “There are seven cats in this painting,” seven is an adjective because it is modifying the noun cats.

Practice

Identify the adjectives in the following sentences:

  1. Of the four seasons, fall is my favorite; I love the red leaves, the cool weather, and the brisk wind.
  2. My roommate, on the other hand, thinks that summer is the best season.
  3. I think she is crazy.
  4. Fall is better than summer. Summer is too hot and muggy to be enjoyable.

Comparable Adjectives

For example, a person may be polite, but another person may be more polite, and a third person may be the most polite of the three. The word more here modifies the adjective polite to indicate a comparison is being made (a comparative), and most modifies the adjective to indicate an absolute comparison (a superlative).

There is another way to compare adjectives in English. Many adjectives can take the suffixes –er and –est (sometimes requiring additional letters before the suffix; see forms for far below) to indicate the comparative and superlative forms, respectively:

great, greater, greatest
deep, deeper, deepest
far, farther, farthest

Some adjectives are irregular in this sense:

good, better, best
bad, worse, worst
little, less, least

Another way to convey comparison is by incorporating the words more and most. There is no simple rule to decide which means is correct for any given adjective, however. The general tendency is for shorter adjectives to take the suffixes, while longer adjectives do not—but sometimes sound of the word is the deciding factor.

more pretentious not pretentiouser

While there is no perfect rule to determine which adjectives will or won’t take –er and –est suffixes, this video lays out some “sound rules” that can serve as helpful guidelines:

A Note about Fun

The adjective fun is one of the most notable exceptions to the rules. If you follow the sound rules we just learned about, the comparative should be funner and the superlative funnest. However, for a long time, these words were considered non-standard, with more fun and most fun acting as the correct forms.

The reasoning behind this rule is now obsolete (it has a lot to do with the way fun became an adjective), but the stigma against funner and funnest remains. While the tides are beginning to change, it’s safest to stick to more fun and most fun in formal situations (such as in academic writing or in professional correspondence).

Practice

What are the correct comparative and superlative forms for the adjectives below?

Adjective Comparative Superlative
fun more fun (or funner, conversationally) most fun (or funnest, conversationally)
red
shimmery
fresh
popular
squishy
quiet
large

Non-Comparable Adjectives

Many adjectives do not naturally lend themselves to comparison. For example, some English speakers would argue that it does not make sense to say that one thing is “more ultimate” than another, or that something is “most ultimate,” since the word ultimate is already an absolute. Such adjectives are called non-comparable adjectives. Other examples include dead, true, and unique.

Note: Native speakers will frequently play with non-comparable adjectives. Although pregnant is logically non-comparable (someone is pregnant or she is not), you may hear a sentence like “She looks more and more pregnant each day.” Likewise extinct and equal appear to be non-comparable, but one might say that a language about which nothing is known is “more extinct” than a well-documented language with surviving literature but no speakers, and George Orwell once wrote “All animals are equal, but some are more equal than others.”
