How to Write "12" in English: A Comprehensive Guide

Knowing how to write numbers in English is an essential skill. While it may seem simple, there are some common mistakes, especially when it comes to writing numbers like "12." In this article, we will discuss the proper way of writing "12" in English.

Writing "12" as a Numeral

The most common way of writing "12" in English is as a numeral. It is a two-digit number composed of the digits "1" and "2." When writing it, there are some rules to follow:

Always use Arabic numerals (0, 1, 2, 3, etc.) instead of Roman numerals (I, II, III, IV, etc.) when writing numbers like "12."

When writing numbers with more than one digit, use a comma (,) as the thousands separator. However, "12" is a two-digit number, so there is no need for a thousands separator.

If you are writing a number that begins a sentence, always spell it out instead of using numerals. For example, "Twelve is my lucky number."

Writing "12" as Words

Another way of writing "12" in English is as words. When writing it, follow these guidelines:

Write "twelve" with a "v" and an "e" at the end, not "twelv."

When writing a check or other legal document, write "twelve dollars and 00/100" rather than just "12."

When writing a date, use the format "December 12, 2020" or "12 December 2020."

Common Mistakes to Avoid

When it comes to writing numbers, there are some common mistakes to avoid:

Confusing "12" with "21." "21" is a two-digit number composed of "2" and "1."

Using both numerals and words in the same document or sentence. Pick one and stick with it.

Misspelling "twelve" as "twelv," "twelf," or "twele."

Failing to add a "th" at the end when writing an ordinal number. For example, "twelfth" instead of "twelve."

In conclusion, knowing how to write "12" in English is essential for effective communication. By following the rules outlined in this article, you can avoid common mistakes and ensure that your writing is clear and accurate.
