COUNTABLE VS UNCOUNTABLE NOUNS
Countable vs. Uncountable Nouns
Did you know that not all nouns are countable in English? Knowing the difference between countable and uncountable nouns can help you in many areas of English grammar.
Countable Nouns
Countable nouns are nouns that can be counted. Most nouns in English are countable.
Examples:
- I have two dogs.
- Sandra has three cars.
- Jessie has ten dollars.
Uncountable Nouns
Uncountable nouns are not counted in English. This usually has to do with the way English speakers think of these nouns. We often picture these nouns as a single concept or one big thing which is hard to divide. Many of these words are countable in other languages, but they ARE NOT countable in English. Generally, we do not use plural forms of these words; however some of these words do end in "s", so don't get confused.
Examples:
- Mack drinks a lot of water.
- Cindy gives great advice.
- Paul enjoys politics. Ends with "s" but uncountable
Uncountable nouns tend to belong to one of the following categories:
Liquids and Gases
- water
- coffee
- milk
- air
- oxygen
Solid and Granular Substances
- wood
- metal
- cheese
- sand
- rice
Energy Words and Forces
- electricity
- sunshine
- radiation
- heat
- magnetism
Subjects
- French
- chemistry
- economics
- science
- math
Grouped Concepts
- fruit
- money
- food
- vocabulary
- news
Information and Abstract Concepts
- information
- advice
- education
- democracy
- intelligence
Uncountable Plurals
Sometimes in English, we do use uncountable nouns in plural forms. This is most commonly done with liquids and substances. It usually takes on the meaning of "cups of", "bottles of" or "types of".
Examples:
- We'll have two coffees. Cups of coffee
- I bought three waters. Bottles of water
- The company produces two leathers. Types of leather
Different Meanings
There are certain words which have multiple meanings. It is possible for one meaning to be countable and the other to be uncountable. Take for example the word "light":
Examples:
- I couldn't see anything because there was no light. Uncountable noun
- The Christmas tree was covered with hundreds of lights. Countable noun
Generally, the rules are still the same. The first use of "light" is a form of energy. The second use of "light" means "small light bulbs", which are normal countable objects.

NEGATIVE PREFIXES
Negative prefixes
In English, one way to make negative statements is by adding negative prefixes to nouns, adjectives, and verbs. Here are some English negative prefixes: a–, dis–, il–, im–, in-, ir–, non–, un–.
For example, the prefix un- can be attached to the adjective happy to create the negative adjective unhappy. Or you can use the negative adverb not. Note that there is no difference in meaning between these two forms.
Tom is happy. | Tom is unhappy. | Tom is not happy. |
Words that take a– as a negative prefix always begin with a consonant.
affirmative | negative | |
political | apolitical | |
sexual | asexual | |
theist | atheist |
Words that take dis– as a negative prefix may begin with a vowel or a consonant.
affirmative | negative | |
agree | disagree | |
comfort | discomfort | |
mount | dismount | |
orient | disorient |
Words that take il– as a negative prefix always begin with the letter l.
affirmative | negative | |
legal | illegal | |
legible | illegible | |
literate | illiterate | |
logical | illogical |
Words that take im– as a negative prefix always begin with the letter m or p.
affirmative | negative | |
mobile | immobile | |
moral | immoral | |
perfect | imperfect | |
possible | impossible |
Words that take in– as a negative prefix can begin with a vowel (except i or u) or a consonant.
affirmative | negative | |
accurate | inaccurate | |
eligible | ineligible | |
organic | inorganic | |
decent | indecent | |
sane | insane |
Note: There are many words that begin with in– that are not words with a negative prefix. For example:

indulge | ||
insist | ||
invoke |
Words that take ir– as a negative prefix always begin with the letter r.
affirmative | negative | |

Remember, not all words that appear to have a negative prefix are negative.
