When I’m giving IELTS writing corrections, I often tell people that they have made a mistake with an uncountable noun. This is hardly surprising. These can be really tricky to learn. In fact, some nouns that are usually countable can even become uncountable in certain situations!
As such, I want to teach you all about uncountable nouns today. This is a big topic, so it will be a long article, but it is an important part of English grammar that all learners should understand.
We can divide nouns into two categories: countable and uncountable. Those that are countable can be counted. For example:
However, some nouns are uncountable. These cannot be counted:
Whenever you learn a new noun, you should check a dictionary to see whether it is countable or not. It should look like this:
Here, you can see the arrow points to the letter C, which means this noun is countable. If it says U, it will be an uncountable noun.
An uncountable noun is one that cannot be counted and cannot take “a” or “an” before it. There are many examples, including common words like “advice.” You could never say “an advice” or “three advices.” Therefore, it is an uncountable noun.
Here are some categories of uncountable nouns:
As you can see, there are many types of uncountable noun.
A word can be both countable and uncountable but, importantly, its meaning changes a little, so it is not exactly the same word. For example:
In the first example, water is used as an uncountable noun. It has no plural form, so we say “some water.” This is by far the most common use.
However, in the second example, it is a countable noun. This is because it refers to “a bottle of water” (ie a countable unit). We sometimes turn uncountable nouns into countable ones when that thing can be divided up into units.
Here’s another example:
You can see that it is again used with a liquid substance. We can do the same with “milk” and “juice” and “whisky,” etc. They are uncountable nouns but, when we think of them as individual glasses or bottles, they can be countable as well.
It is not only liquids that this applies to:
In the first example, we consider all the hairs on someone’s head as a single unit called “hair.” In the second, we consider each individual hair as a countable unit.
The most important rule is that uncountable nouns should not be counted. Thus, we cannot use a number in front of them and we do not add “-s” at the end to pluralise them:
Likewise, we do not use “a” or “an” before these words:
Instead, we have other phrases we use with uncountable nouns. (Learn more about articles here.)
You can see from my examples above that we have a few words that we can use to suggest a quantity in relation to uncountable nouns. There are various words and phrases that can be used:
For negative sentences, we use “any”:
Likewise, there are specific expressions that can be used for certain uncountable nouns. These are often units of measurement or forms of container. For example:
The word “bread” is uncountable, but actually we can count it by making it into a specific countable unit, a loaf. Example:
Of course, there are many such words. Here are some more examples:
You need to have a good grasp of these common collocations if you want to get a good score for Lexical Resource.
As we just saw, it is possible to count uncountable nouns if we use certain units to measure them. Of course, not all uncountable nouns can be treated this way, and most of them have unique words or phrases that are used to make them countable.
For example, we can say:
In the first example, “lightning” is an idea, a concept. In the second, it is a physical thing that has a real presence. Importantly, the unit “a bolt of” means it is suddenly countable. We could say, for example:
Another example is the word “work.” As an uncountable noun, this refers to the idea of work. However, “works” means something different entirely:
Uncountable nouns are treated as being grammatically singular, so we must keep this in mind when thinking about subject-verb agreement:
Try to remember this especially when using uncountable nouns that refer to many things, such as “furniture”:
Even though this implies several or many items of furniture, it is still treated as singular.
When we ask questions about the quantity of an uncountable noun, we should use “any” or “much”:
However, when we offer something, we use “some”:
Here are some common uncountable nouns:
There are many, many more words to learn! I suggest that you make a note of whether a word is countable or uncountable when you learn new vocabulary.
Finally, here are some examples of mistakes I often see people make using uncountable nouns:
