Frequently Asked Questions
What is the difference between countable and uncountable nouns?
Countable nouns can be counted and have a plural form: a book → books, an apple → apples. Uncountable nouns cannot be counted — they have no plural and cannot take 'a' or 'an': water, money, music, advice, information. To count an uncountable noun, use an expression like 'a piece of advice' or 'a glass of water'.
Why is 'advices' wrong?
'Advice' is an uncountable noun in English, so it has no plural form — 'advices' does not exist. Say 'some advice', 'a lot of advice', or 'a piece of advice'. The same applies to information, news, furniture, luggage, and equipment — none of these take a plural -s.
How do you spell irregular plurals?
Some nouns have irregular plurals that must be learned: child → children, man → men, woman → women, foot → feet, tooth → teeth, person → people, mouse → mice. A few nouns do not change at all: fish, sheep, and deer stay the same in the plural.
When do you use 'much' and when 'many'?
Use 'many' (and 'few', 'fewer') with countable plural nouns: many books, fewer cars. Use 'much' (and 'little', 'less') with uncountable nouns: much water, less time. A common mistake is 'less cars' — it should be 'fewer cars'.
