Adjectives are fundamental building blocks in English grammar, serving to enrich our descriptions and provide crucial details about nouns. They help us understand what a person or a thing is like, offering information about quality, size, age, temperature, shape, colour, and origin. Mastering adjectives is key to clear and expressive communication for any student of English.
What are Adjectives in English Grammar?
An adjective is a word or phrase that modifies a noun or pronoun. It provides additional information, making sentences more descriptive and vivid. For instance, instead of just saying "a house," you can say "a large house" or "a beautiful house," immediately giving the listener or reader a clearer picture.
How Adjectives are Formed
Adjectives can come in various forms, from simple words to complex compounds. Some words inherently function only as adjectives (e.g., big, nice). Others are transformed through derivational morphemes or suffixes:
- From Nouns:
- -al: person – personal
- -ary: custom – customary
- -ful: beauty – beautiful
- -ish: fool – foolish
- -ly: friend – friendly
- -ous: nerve – nervous
- -y: cloud – cloudy
- From Verbs:
- -able: agree – agreeable
- -ent: depend – dependent
- -ible: sense – sensible
- -ive: attract – attractive
Participial Adjectives are formed from verbs using -ing (present participle) and -ed (past participle) endings. Examples include interesting vs. interested, disappointing vs. disappointed, and boring vs. bored.
Prefixes are often added to adjectives to create a negative effect:
- dis-: agreeable – disagreeable
- un-: pleasant – unpleasant
- im-: possible – impossible
- ir-: regular – irregular
Compound Adjectives are frequently formed in several ways:
- With participles: absent-minded, short-sighted, time-consuming
- With prefixes and suffixes: water-resistant, health-conscious
- With cardinal numbers and nouns: a five-year-old girl, a ten-minute-break
Types of Adjectives: Gradable vs. Non-Gradable
Understanding whether an adjective is gradable or non-gradable helps in using intensifiers correctly.
- Gradable Adjectives can be premodified by words like very, too, and enough. They can also take comparative and superlative forms (e.g., big, bigger, biggest).
- Non-gradable Adjectives cannot be premodified in this way and typically do not form comparative or superlative degrees (e.g., dead, perfect, unique).
Adjective Position: Attributive, Predicative, and Postpositive
From a syntactic perspective, adjectives typically appear in two main positions: attributive and predicative. Some rare cases allow for postpositive placement.
Attributive Adjectives
Attributive adjectives come before the noun they modify, usually between a determiner and the noun in a noun phrase. They directly modify the noun. For example: "My favourite book." They answer the question "What kind?"
Predicative Adjectives
Predicative adjectives occur without a noun in the predicate of a sentence, typically appearing after linking verbs such as to be, look, or seem. They describe the subject of the sentence. For example: "Mrs. Smith is 80." or "She is very old now."
Most adjectives are central adjectives, meaning they can be used both attributively and predicatively. However, some adjectives have different meanings depending on their position:
- "My old friend hasn't arrived yet." (attributive = long-standing)
- "Mrs. Smith is 80. She is very old now." (predicative = age)
- "Jane is late." (predicative = not on time)
- "My late cousin..." (attributive = deceased)
Adjectives Used Only Predicatively
Some adjectives are exclusively used in the predicative position:
- Describing health: well, unwell, faint (when referring to health), ill. (Note: "a faint sound" uses 'faint' attributively, but it doesn't refer to health.)
- Beginning with 'a-': ablaze, afloat, afraid, alive, asleep, awake. (Compare with attributive forms: burning, floating, live/living, sleeping, waking).
- Describing feelings/reactions: content, pleased, glad, upset, sorry.
- Followed by prepositions.
Adjectives Used Only Attributively
Conversely, some adjectives are only used in the attributive position:
- Intensifiers: sheer, mere, utter.
- With the sense of 'very': complete nonsense, perfect nonsense, total nonsense, close nonsense, pure nonsense.
- Restricting the reference of nouns: the only way, main problem, certain value, sole interest.
Postpositive Adjectives
Adjectives can sometimes be postpositive, meaning they immediately follow the noun or pronoun they modify. This is less common but occurs in specific phrases:
- Fixed phrases: Attorney General, President Elect, Heir Apparent, Governor General, Asia Minor, sum total, time immemorial, body politic.
- Temporary attributes: Adjectives like absent, present, concerned, involved, and responsible are postpositive when they describe temporary rather than permanent attributes (e.g., "the students present").
- Reduced relative clauses: A postpositive adjective can often be seen as a reduced relative clause (e.g., "something that is useful" becomes "something useful").
Nouns as Adjective Modifiers and Word Order
Nouns can modify other nouns, behaving like adjectives. For example: "a gold medal," "a gold chain." If the product is made of the material, they are used without derivational morphemes, with exceptions like wooden chair and woolen pullover.
However, if these nouns have a metaphorical meaning (like...), they often take derivational morphemes:
- gold-en sunlight vs. a gold medal
- the silver-y light of the moon vs. a silver ring
- a ston-y face vs. the stone age
- a ston-y silence vs. a stone wall
- a silky voice vs. a silk blouse
- silken hair vs. a silk blouse
- brazen corruption vs. brass objects
When using more than one adjective to describe a noun, a general word order is followed to ensure clarity and natural flow:
Quality + Size / Age / Shape + Colour + Origin + Past Participle + Compound Noun
For example: "a beautiful (quality) large (size) old (age) round (shape) red (colour) French (origin) painted (past participle) wooden (compound noun) table."
Adjectives Denoting Classes of People or Abstract Concepts
Adjectives can also function as heads of noun phrases, referring to groups of people or abstract concepts. There are three main types:
- Adjectives premodifying personal nouns can become NP heads denoting classes of people (e.g., "the old people" becomes "the old," referring to a group). Other examples include "the young," "the poor," "the innocent," "the blind."
- Adjectives denoting nationalities can become NP heads (e.g., "the Dutch," "the Irish," "the French").
- Adjectives with abstract reference can also be NP heads. They typically take singular concord (e.g., "the exotic," "the unreal," "the exciting," "the unknown").
Frequently Asked Questions (FAQ) about English Adjectives
What is the primary function of an adjective?
The primary function of an adjective is to modify a noun or pronoun, providing more specific information about its qualities, characteristics, or state. It helps to describe and specify what a person, place, or thing is like.
Can nouns act like adjectives in English?
Yes, nouns can function as adjective modifiers when they precede and describe another noun. For example, in "a gold medal," 'gold' is a noun but acts descriptively like an adjective, telling us what kind of medal it is.
What is the difference between attributive and predicative adjectives?
Attributive adjectives appear before the noun they modify (e.g., "a red car"), while predicative adjectives appear after a linking verb (like 'to be') and refer back to the subject (e.g., "The car is red").
Why is adjective word order important?
Adjective word order is crucial for clarity and natural-sounding English. There's a conventional sequence (e.g., quality, size, age, color, origin) that native speakers intuitively follow, making descriptions easier to understand and process.
What are participial adjectives, and how are they formed?
Participial adjectives are formed from the -ing (present participle) or -ed (past participle) forms of verbs. They function as adjectives to describe nouns. Examples include "an interesting book" (the book causes interest) and "an interested reader" (the reader feels interest).
