English nouns are divided into two categories:
- Countable nouns: can be counted, have singular and plural forms. a book → two books.
- Uncountable nouns: cannot be directly counted, have no plural form. water, music, money, information.
我I 买了bought 三three 苹果apples.
I bought three apples. (Countable)
我I 需要need 一些some 水water.
I need some water. (Uncountable, no ~~waters~~)
Note
- Uncountable nouns take a singular verb: The news is good. (The news is good.)
- To count uncountable nouns, use measure words: a glass of water, a piece of information.
