Understanding the different meanings and contexts in which forty five appears helps us appreciate the versatility of this phrase in English communication. This topic explores various aspects of forty five and how its meaning can shift based on usage.
Spelling Out Numbers: Forty Five or Forty-Five?
When it comes to spelling out numbers in English, there is often confusion about when to use hyphens. Forty five is commonly seen without a hyphen, but the correct form in formal writing is forty-five. According to standard English grammar rules, numbers between 21 and 99 that are written out should be hyphenated. Therefore, the grammatically correct way to spell 45 in words is forty-five.
However, in many casual or digital contexts, people tend to drop the hyphen. This is especially true in headlines, informal writing, or where hyphenation rules are not strictly enforced. The meaning remains the same, but understanding proper usage is important for those concerned with clear and correct writing.
When to Use Numerals or Words
Writers often wonder whether to write 45 or forty-five. The answer depends on the style guide in use:
- AP Style: Use numerals for numbers 10 and above. So, write 45.
- Chicago Style: Spell out numbers from zero to one hundred in nontechnical writing: forty-five.
- Academic Writing: Typically follows Chicago or APA style, requiring clarity and consistency.
Understanding which style applies will guide your choice between spelling out forty-five or using the numeral 45.
