When you’re finalizing the month-end report for your finance department, you might pause to examine whether that hyphen belongs there. It’s a common source of confusion among professionals, and even style guides don’t always agree. The distinction between “month-end” and “month end” isn’t merely about punctuation—it reflects specific grammatical functions that can affect your document’s clarity and professionalism. Comprehending these nuances will sharpen your business writing and maintain consistent usage across your communications.
key Takeaways
- Use “month-end” with a hyphen when it functions as an adjective modifying another word, as in “month-end report.”
- Write “month end” as two separate words when using it as a noun, such as “The payment is due at month end.”
- Both “month-end” and “month end” are correct, but their usage depends on their grammatical function in the sentence.
- Alternative phrases like “the end of the month” or “the month’s end” can avoid confusion about hyphenation entirely.
- Major style guides recommend “month-end” as a hyphenated adjective and “month end” as a two-word noun for professional writing.
The Difference Between Month-End and Month End
The two key distinctions between “month-end” and “month end” lie in their grammatical roles and usage patterns.
When you’re using this month end terminology as an adjective to describe something, you’ll need the hyphenated form “month-end” – for example, “month-end results” or “month-end reporting.” However, when you’re referring to the actual end of a month as a noun, you can use either the open compound “month end” or the closed form “monthend.”
Understanding these differences is vital, just as it is with month end versus year end conventions. You can also opt for alternative expressions like “the month’s end” or “the end of the month” when you want to avoid any confusion about hyphenation rules. The Oxford Dictionary supports using “month-end” for both purposes.
Usage Rules and Common Examples
Now that we’ve established the core differences between these terms, let’s examine their practical applications through real-world examples.
When you’re writing business documents, you’ll use “month-end” with a hyphen when it modifies another word: “The month-end report shows increased profits” or “We’ll review the month-end statistics tomorrow.” Without a modifier, you’ll use “month end” as two separate words: “Payment is due at month end.”
While flexible hyphenation rules allow for “monthend” as a closed compound, particularly in British English, the most widely accepted forms remain “month-end” (hyphenated) and “month end” (open). You can also opt for alternative phrasing like “at the month’s end” or “at the end of the month” when determining appropriate usage context.
The Evolution of Monthend as a Closed Compound
While “monthend” may seem like a modern linguistic shortcut, this closed compound has gradually gained acceptance, particularly in British English and specialized financial contexts. The historical shift towards monthend reflects a broader trend in language evolution, where frequently paired words merge into single units.
Language evolution naturally fuses common word pairs, as seen in monthend’s growing acceptance within British English and financial writing.
You’ll notice this growing acceptance of monthend through:
- Its recognition by major style guides as a valid alternative to “month-end”
- Its prevalent use in financial and accounting documentation
- Its alignment with other accepted closed compounds like “childcare”
- Its increasing adoption by British organizations and publications
When deciding whether to use “monthend,” consider your audience and style requirements. While British English speakers may find it natural, American readers might prefer the hyphenated or open form. The key is maintaining consistency within your chosen style throughout your documentation.
Alternative Ways to Express Month End
Beyond the standard variations of “month-end,” “mouth end,” and “monthend,” you’ll find several alternative expressions that can effectively convey the same temporal concept.
When you’re preparing month end accounting practices or discussing month end financial reporting, you can opt for more formal expressions like “the month’s end” or “the end of the month.” These alternatives can add variety to your writing while maintaining professional clarity. For instance, instead of writing “The month-end report is due,” you might say “The report is due at the end of the month.” These variations help you avoid repetitive language in your documents while preserving the precise meaning. You’ll find that choosing the right form depends on your specific context and whether you’re using it as a noun or an adjective.
Professional Style Guides and Industry Standards
Leading style guides and industry manuals offer clear direction on the proper usage of “month-end” versus “month end.” The Associated Press Stylebook and Chicago Manual of Style both recommend using “month-end” as a hyphenated adjective when modifying nouns (e.g., “month-end report”) and “month end” as a two-word noun phrase (e.g., “at month end“).
When using month-end as an adjective, hyphenate it. Leave it as two words when indicating a point in time.
When you’re emphasizing consistency with professional norms, follow these style guide recommendations:
- Use “month-end” as a hyphenated adjective before nouns
- Write “month end” as two separate words when it functions as a noun
- Consider Oxford Dictionary’s flexibility in accepting both hyphenated and open compound forms
- Follow industry-specific standards, such as Morningstar’s preference for “month-end” in financial reporting
While addressing ambiguity in use of prefixes, remember that the closed form “monthend” remains less common in professional contexts.
