Numeral Adjectives

What Are Numeral Adjectives?

Numeral adjectives are words that modify nouns by providing numerical information. They answer questions like “How many?” or “Which one in order?” These adjectives are essential for clear and precise communication in both spoken and written English.

Types of Numeral Adjectives

Cardinal Numeral Adjectives

Cardinal numeral adjectives express quantity and answer the question “How many?” They are particularly useful when dealing with countable nouns.

Examples:

  • One book
  • Five apples
  • Twenty students

Usage: Use cardinal numeral adjectives when you need to specify an exact number of items or people.

Ordinal Numeral Adjectives

Ordinal numeral adjectives indicate the order or position of something in a sequence. These fall under the broader category of types of adjectives.

Examples:

  • First place
  • Third chapter
  • Tenth anniversary

Usage: Employ ordinal numeral adjectives when describing the position or rank of an item within a group or series.

Multiplicative Numeral Adjectives

Multiplicative numeral adjectives express how many times something occurs or is multiplied. These are a specific type of quantitative adjectives.

Examples:

  • Double the amount
  • Triple check
  • Quadruple threat

Usage: Use multiplicative numeral adjectives to indicate repetition or multiplication of an action or quantity.

Fractional Numeral Adjectives

Fractional numeral adjectives represent parts of a whole.

Examples:

  • Half an hour
  • Two-thirds majority
  • Quarter-inch gap

Usage: Apply fractional numeral adjectives when discussing portions or divisions of a whole.

  2. Clarity: They help avoid ambiguity in communication.
  3. Efficiency: Numeral adjectives convey numerical information concisely.

FAQs

What’s the difference between cardinal and ordinal numeral adjectives? Cardinal numeral adjectives express quantity (e.g., three books, five apples) and answer the question “How many?”, while ordinal numeral adjectives indicate order or position (e.g., third place, fifth element) and answer the question “Which one in order?”.
How do I know when to spell out numbers and when to use numerals? Generally, in non-technical writing, spell out numbers from one to nine and use numerals for 10 and above. However, be consistent within a sentence or paragraph. For technical or scientific writing, numerals are often preferred for all numbers. Always check your style guide for specific rules.
Can numeral adjectives be used with uncountable nouns? Yes, but with some restrictions. Cardinal numeral adjectives are typically not used with uncountable nouns. Instead, you might use quantifiers or fractional numeral adjectives. For example, “two pieces of furniture” instead of “two furniture,” or “half the water” instead of “two water.”
How do multiplicative numeral adjectives differ from cardinal numeral adjectives? Multiplicative numeral adjectives (e.g., double, triple) express how many times something occurs or is multiplied, while cardinal numeral adjectives (e.g., two, three) simply express quantity. For instance, “double check” means to check twice, while “two checks” refers to a quantity of checks.
Are there any special rules for using numeral adjectives in dates? Yes, when using numeral adjectives in dates, we typically use ordinal numbers for the day of the month in British English (e.g., “the 5th of June”), while in American English, cardinal numbers are more common (e.g., “June 5”). However, when writing the date numerically, both systems use cardinal numbers (e.g., 5/6/2023 or 6/5/2023). Understanding these differences is part of mastering English grammar tenses.
