English Grammar CHAPTER 11 ADJECTIVES USED AS NOUNS

Chapter 11: Adjectives Used As Nouns

Welcome to Chapter 11! In English grammar, words are very flexible. Sometimes, a word that is normally used to describe something (an adjective) puts on a disguise and acts like the name of something (a noun). Additionally, sometimes a noun steps in to do the job of an adjective! Understanding these roles will make your English sound much more advanced and natural.

Topic 1: Adjectives as Plural Nouns (Classes of Persons)

1. Explanation

We often use an adjective with the article "the" before it to talk about a whole group or class of people who share that quality. When we do this, the adjective acts exactly like a plural noun.

For example, instead of saying "Rich people know not how poor people live," we can simply drop the word "people" and say: "The rich know not how the poor live."

2. Important Rules and Exceptions

• Rule 1: Always Plural. Because phrases like "the rich" or "the brave" refer to a group of people, they always take a plural verb (are, have, do).
• Rule 2: No 's' Allowed. Do NOT add an 's' to the adjective. We say "the poor," never "the poors."

3. Solved Examples

• The cautious (= cautious persons) are not always cowards.
• The rich (= rich people) know not how the poor (= poor people) live.
• The wicked (= wicked people) flee when no man pursueth, but the righteous (= righteous people) are bold as a lion.
• Blessed are the meek.

4. Additional Practice Exercises

Fill in the blanks with the correct form of the verb or adjective:

1. The strong (is/are) meant to protect the weak.
2. We must always help the (homeless/homelesses).
3. The blind (need/needs) our assistance to cross the busy street.

5. Complete Solutions and Explanations

1. are. Explanation: "The strong" refers to all strong people, so it acts as a plural noun and takes the plural verb "are".
2. homeless. Explanation: We never add an 's' to an adjective acting as a noun class.
3. need. Explanation: "The blind" is a plural subject, so it takes the plural verb "need" (without the 's').

6. Common Mistakes and Tips

Mistake: Saying "The riches are happy" or "The rich is happy."

Tip: Think of "the + adjective" as a shortcut for "the [adjective] people". Since "people" is plural, the shortcut is also plural and never needs an 's'.

7. Quick Summary

The + Adjective = A plural group of people. (e.g., The brave = Brave people). Always use a plural verb.

Topic 2: Adjectives as Singular Nouns (Abstract Qualities)

1. Explanation

Sometimes, placing "the" before an adjective does not refer to people, but rather to an abstract idea, concept, or quality. When used this way, the adjective acts as a Singular Noun.

2. Important Rules and Exceptions

• Rule: Because these phrases refer to an abstract concept (like "beauty" or "futurity"), they are always treated as singular and take a singular verb.

3. Solved Examples

• The future (= futurity or time to come) is unknown to us.
• He is a lover of the beautiful (= beauty in general).
• He stepped into the unknown (= the unknown world/situation).

4. Additional Practice Exercises

Identify whether the underlined phrase acts as a Plural Noun (Class of People) or a Singular Noun (Abstract Quality):

1. She prefers reading about the supernatural.
2. The elderly require special care during winter.

5. Complete Solutions and Explanations

1. Singular Noun (Abstract Quality): "The supernatural" refers to the concept of things beyond nature, not a group of people.
2. Plural Noun (Class of People): "The elderly" refers to elderly people.

6. Common Mistakes and Tips

Mistake: Using a plural verb for abstract qualities (e.g., "The beautiful are subjective.")

Tip: If you can replace the phrase with an abstract noun ending in "-ity" or "-ness" (like beauty, weirdness), treat it as a singular object.

7. Quick Summary

The + Adjective = An abstract concept. (e.g., The beautiful = Beauty). Always use a singular verb.

Topic 3: Adjectives that have BECOME Nouns

1. Explanation

Some adjectives have been used as nouns for so long in the English language that they have permanently transformed. They are officially recognized as nouns, which means they can take an 's' to become plural!

2. Categories and Solved Examples

These fully converted words fall into three main categories:

(a) Those derived from Proper Nouns (Nationalities):

• Australians (From the adjective Australian).
• Canadians (From the adjective Canadian).
• Italians (From the adjective Italian).

(b) Words denoting persons:

• Juniors, seniors, inferiors, superiors. (Example: Respect your seniors).
• Mortals, nobles, criminals, savages, elders, minors. (Example: We are all mere mortals).

(c) Words denoting things generally:

• Secrets, totals, liquids, solids. (Example: Ice is a solid, water is a liquid).
• Exception Rule: Some of these words are used as nouns ONLY in the plural form. Examples: valuables, eatables. (You cannot say "I lost my valuable"; you must say "I lost my valuables").

3. Additional Practice Exercises

Choose the correct form of the word in brackets:

1. Keep your (valuable / valuables) in the hotel safe.
2. He is one of the worst (criminal / criminals) in the city.
3. The movie is restricted to adults; (minor / minors) are not allowed.

4. Complete Solutions and Explanations

1. valuables. Explanation: As a noun meaning personal property, it is only used in the plural.
2. criminals. Explanation: "Criminal" has become a fully-fledged noun, so we add an 's' to make it plural.
3. minors. Explanation: "Minor" referring to an underage person takes an 's' in the plural.

5. Common Mistakes and Tips

Mistake: Confusing Rule 1 (The rich) with Rule 3 (Mortals). Saying "the riches" (incorrect) or "the mortal are" (incorrect).

Tip: Memorize the specific words in Category 3 (juniors, seniors, criminals, mortals). These are allowed to have an 's'. General adjectives like poor, rich, brave, and weak are NOT allowed to have an 's'.

6. Quick Summary

Certain adjectives (nationalities, relative ages/ranks, and some states of matter) have evolved into regular nouns and can be pluralized with an 's' (e.g., Canadians, seniors, liquids).

Topic 5: Nouns used as Adjectives

1. Explanation

Just as adjectives can act like nouns, nouns can act like adjectives! When you place a noun directly in front of another noun to describe it, the first noun is doing the job of an adjective.

2. Important Rules and Exceptions

Rule: Even if the describing noun represents something plural in reality, it is almost always written in the singular form when acting as an adjective.

For example, a store that sells shoes is a "shoe store," not a "shoes store."

3. Solved Examples

• I met a little cottage girl. (Cottage is a noun, but here it describes the girl).
• He is always playing computer games. (Computer describes what kind of games).
• The school bus is late. (School describes the bus).
• I drank from a water bottle. (Water describes the bottle).

4. Additional Practice Exercises

Identify the noun acting as an adjective in the following sentences:

1. She spilled coffee on the kitchen table.
2. We watched an exciting action movie.

5. Complete Solutions and Explanations

1. kitchen. "Kitchen" is a noun, but here it describes the type of table.
2. action. "Action" is a noun, but here it describes the genre of the movie.

6. Common Mistakes and Tips

Mistake: Pluralizing the noun acting as an adjective (e.g., writing "teethbrush" instead of "toothbrush").

Tip: Remember that adjectives in English do not have plural forms. So, when a noun acts like an adjective, it strips off its plural 's'!

7. Quick Summary

When two nouns sit next to each other, the first noun describes the second one, functioning exactly like an adjective. Keep the describing noun singular.
