Countable vs. Uncountable Nouns: Simple Rules for Less vs. Fewer, Many vs. Much

Writers and speakers often confuse countable and uncountable nouns. This confusion leads to mistakes with words like fewer vs. less and many vs. much. Once you understand the rules, you will never mix them up again.

1. What Are Countable and Uncountable Nouns?

Countable Nouns

• You can count them one by one.

• They have singular and plural forms.

Examples:

Uncountable Nouns

• You cannot count them individually.

• They do not usually have a plural form.

Examples:
water, rice, sugar, information ✅
Not: waters, rices, sugars ❌ (unless in special contexts)

2. Fewer vs. Less

Rule:

• Use fewer with countable nouns.

• Use less with uncountable nouns.

Examples:
