Master Hyphenating Numbers: Key Guide for Language Learners

Introduction to Hyphenating Numbers

Ever wondered when to hyphenate numbers? For language learners, number hyphenation can be a tad tricky. However, mastering the art of hyphenating numbers is a vital skill that can make your writing more precise, structured, and professional.

This article unveils the mystery behind this typographical conundrum and offers a comprehensive guide on how to hyphenate numbers correctly. Packed with examples, it’s aimed at helping understand the principles of dashes in numbers and providing clear, concise guidance.

What is Number Hyphenation?

Number hyphenation, or using hyphens in numbers, refers to the practice of applying the typographical symbol—the hyphen (-)—to written numbers. This is done primarily in compound numbers and fractions.

When to Hyphenate Numbers?

The main rule about when to hyphenate numbers is related to written numbers both compound (from twenty-one to ninety-nine) and fractions. Here are clear examples to help you understand the concept.

• Compound Numbers: In English, you hyphenate numbers from twenty-one through ninety-nine. So, instead of writing ‘forty three’, we write ‘forty-three’.
• Fractions: When fractions are expressed in words, they should be hyphenated. For instance, ‘two-thirds’ is the correct hyphenation.

Now let’s dive deeper into the rules and exceptions of hyphenating numbers.

Hyphenating Compound Numbers

Compound numbers between twenty-one and ninety-nine are hyphenated. Single-digit numbers do not require hyphens unless they’re part of a larger, compound number. For instance, in ‘twenty-two’, there’s a hyphen, though not in ‘twenty’ and ‘two’ written separately.

Hyphenating Fractions

Fractions should always be hyphenated when written out in words. For example, “two-thirds”, “three-quarters”, or “four-fifths”. Remember, the hyphen is not required when the fraction is used as a modifier and follows a number. For instance, ‘4 1/2 years old’ doesn’t require a hyphen.

Hyphenating Numbers: Common Mistakes and Exceptions

While the rules above cover the basic scenarios for hyphenating numbers, there are exceptions and nuances worth noting to avoid common pitfalls. For instance, numeral adjectives are not hyphenated. That means phrases like ‘a four year old boy’ should be written without hyphens.

Furthermore, in the case of compound adjectives that include numbers, a hyphen is used for clarification. For example, we write a ‘5-page report’, not a ‘five page report’, where ‘5-page’ is an adjective describing the report.

Conclusion

Mastering how to hyphenate numbers is a key step towards writing like a pro in English and other languages. We hope this guide demystifies the rules and offers helpful guidance to perfect your language skills. Remember, the golden rule is practice, so keep writing and with time, hyphenating numbers will become second nature to you.
