Months or Monthes: Which Is Correct? 📅

“Months” is the correct spelling, while “monthes” is incorrect. Use “months” as the plural form of “month” when talking about two or more months.

Months or monthes—which spelling is correct? If you have ever hesitated before writing this word, the answer is simple: months is correct, and monthes is a misspelling. The confusion often happens because many English words form their plurals by adding -es, but month does not follow that pattern. Its plural is made by adding -s, giving us months.

The word month means one calendar month, while months means more than one. For example, you can write, “The course lasts three months,” or “I have been working here for six months.” In contrast, monthes should not be used in standard English because it is not the accepted plural spelling of month.

So, if you are writing an email, school assignment, website article, social media post, or professional document, choose months every time. Remembering this simple rule can help you avoid an easy-to-miss spelling mistake.

In this guide, you’ll learn the exact difference between months and monthes, why months is correct, how the plural is formed, whether pronunciation changes, and how to use the word naturally in sentences.

The Origin of Months or Monthes

The word month is very old. It comes from Old English mōnath, which was connected to the word for moon.

This connection makes sense because early calendars were closely linked to the changing phases of the moon.

Over time, the spelling changed as English developed. The modern word became month.

When English speakers needed the plural form, they added the normal plural ending -s:

month → months

The incorrect form monthes may look reasonable because many English nouns use -es in the plural.

For example:

• box → boxes
• church → churches
• class → classes
• dish → dishes

But month does not need -es.

So, the standard spelling is:

month → months
