Countable nouns are for things we can count
dog, horse, man, shop, idea.
They usually have a singular and plural form.
two dogs, ten horses, a man, six men, the shops, a few ideas.
Uncountable nouns are for the things that we cannot count
tea, sugar, water, air, rice.
They are often the names for abstract ideas or qualities.
knowledge, beauty, anger, fear, love.
They are used with a singular verb. They usually do not have a plural form. We cannot say sugars, angers, knowledges.
We cannot use a/an with these nouns. To express a quantity of one of these nouns, use a word or expression like:
some, a lot of, a piece of, a bit of, a great deal of...
Some nouns are countable in other languages but uncountable in English. Some of the most common of these are:
accommodation | news |
BE CAREFUL with the noun 'hair' which is normally uncountable in English:
It can also be countable when referring to individual hairs:

Words can be combined to form compound nouns. These are very common, and new combinations are invented almost daily. They normally have two parts. The second partidentifies the object or person in question (man, friend, tank, table, room). The first parttells us what kind of object or person it is, or what its purpose is (police, boy, water, dining, bed):
What type / what purpose | What or who |
police | man |
boy | friend |
water | tank |
dining | table |
bed | room |
The two parts may be written in a number of ways :
1. as one word.
Examples policeman, boyfriend
2. as two words joined with a hyphen.
Examples dining-table
3. as two separate words.
Examples fish tank.
There are no clear rules about this - so write the common compounds that you know well as one word, and the others as two words.
The two parts may be: | Examples |
noun + noun | bedroom water tank motorcycle printer cartridge |
noun + verb | rainfall haircut train-spotting |
noun + adverb | hanger-on passer-by |
verb + noun | washing machine driving licence swimming pool |
verb + adverb* | lookout take-off drawback |
adjective + noun | greenhouse software redhead |
adjective + verb | dry-cleaning public speaking |
adverb + noun | onlooker bystander |
adverb + verb* | output overthrow upturn input |
Compound nouns often have a meaning that is different from the two separate words.
Stress is important in pronunciation, as it distinguishes between a compound noun (e.g.greenhouse) and an adjective with a noun (e.g. green house).
In compound nouns, the stress usually falls on the first syllable:
a 'greenhouse = place where we grow plants (compound noun)
a green 'house = house painted green (adjective and noun)
a 'bluebird = type of bird (compound noun)
a blue 'bird = any bird with blue feathers (adjective and noun)
*Many common compound nouns are formed from phrasal verbs (verb + adverb or adverb + verb).
breakdown, outbreak, outcome, cutback, drive-in, drop-out, feedback, flyover, hold-up, hangover, outlay, outlet, inlet, makeup, output, set-back, stand-in, takeaway, walkover.
Most nouns form the plural by adding -s or -es.

hat | hats |
