1. Overview:
"More," "less," and "fewer" are used to compare quantities. "More" is used for larger amounts, "less" is used for uncountable nouns, and "fewer" is used for countable nouns. They help us express differences in quantity clearly.
2. Cases of Usage:
Case 1: Use "more" to indicate a larger quantity of something.
Example: I need more time to finish my homework.
Case 2: Use "less" with uncountable nouns to indicate a smaller amount.
Example: I have less money than I thought.
Case 3: Use "fewer" with countable nouns to indicate a smaller number.
Example: There are fewer students in the class this year.
3. Exceptions or Things to Pay Attention To:
"Less" is often used in informal speech with countable nouns, but this is not grammatically correct. For example, saying "less apples" is incorrect; it should be "fewer apples." Remember that "less" is for uncountable nouns, like water or sugar, while "fewer" is for things you can count, like books or chairs.
