Tips for Using Adjectives of Number Correctly
To really master adjectives of number, keep these tips in mind:
- Use cardinal numbers when you are counting the quantity.
- Use ordinal numbers when referring to position or rank.
- Be aware of the difference between these and those — e.g., "two apples" (near) vs. "two apples over there."
- Remember that numbers at the start of sentences should often be written out, e.g., "Twenty students attended the class."
Common Mistakes and How to Avoid Them
Even native speakers slip up on adjectives of number sometimes. Here are common pitfalls and solutions:
| Mistake | Explanation | How to Correct |
|---|---|---|
| Using plural forms incorrectly | e.g., "Two car" | Say "two cars" (noun plural) |
| Confusing cardinal and ordinal | e.g., "First car" when meaning two cars | Use cardinal "two cars" or ordinal "first car" based on context |
| Overusing numbers in formal writing | Numbers over 10 often written out | Write words for numbers up to 10, numerals for larger numbers in formal writing too, but keep consistency. |
| Forgetting to match adjective with noun | e.g., "Three dogs" vs. "Three dog" | Ensure matching in number, with correct pluralization |
Similar Variations and Related Words
Additionally, mastering adjectives of number includes understanding related concepts:
- Quantifiers: some, any, many, few, several (less specific but useful)
- Partitives: some of, none of, a lot of etc.
- Distributives: each, every, either, neither
Knowing these helps you build more complex sentences and add variety in expression.
Why Is Using Adjectives of Number Important?
Think about it: accurate description of quantities makes your communication clear and effective. In daily conversation, storytelling, academic writing, or business reports, expressing how many or which order things are in is essential. For example, saying, “I have three projects to complete” is much more specific than “I have some projects.”
