18th or 18 – Which is Correct?

In the English language, numbers can be written using either numerals (18) or words (eighteen). Both forms are correct, but the choice between them depends on the context and style guide being used.

When it comes to formal writing, such as academic papers, reports, or legal documents, it is generally recommended to use numerals for numbers above ten. This convention helps maintain consistency and readability, especially when dealing with large sets of data or complex numerical analysis. For example, in a scientific paper discussing the results of an experiment, it would be appropriate to write “The temperature increased by 18 degrees Celsius.” The use of numerals here allows for precise and efficient communication of the measurement.

On the other hand, when writing literature, creative works, or other forms of informal writing, using words for numbers can add a sense of warmth and familiarity. This choice can help create a more relatable and engaging experience for the reader. For instance, a description of a character in a novel might say, “She was just 18 years old, full of dreams and aspirations.” Here, the use of the word “eighteen” evokes a more vivid image and personal connection.

Moreover, certain style guides, such as the Associated Press (AP) Stylebook, have specific rules regarding the use of numerals versus words. According to AP style, numerals should be used for ages, percentages, measurements, and dates. For example, “The 18-year-old student scored 98% on the test, which took place on October 18th.” Adhering to a particular style guide ensures consistency within a piece of writing and aligns with widely accepted grammar conventions.

However, it is important to note that there are exceptions to these guidelines. For example, when starting a sentence, it is generally preferred to write out the number in words rather than using a numeral. Instead of saying, “18 students attended the lecture,” it is better to rephrase it as “Eighteen students attended the lecture.” This helps maintain flow and readability, as numerals can interrupt the natural rhythm of a sentence.

Furthermore, there are cases where using a numeral is more appropriate due to specific cultural or contextual considerations. For example, in some Asian countries, it is common practice to avoid the number four in writing or any form of communication due to superstitions associated with the number. In such cases, it would be more appropriate to write “18” instead of “eighteen” to respect cultural sensitivities.

In conclusion, both “18” and “eighteen” are correct ways to represent the number. The choice between them depends on the context, style guide, and personal preference of the writer. Numerals are often used in formal writing, whereas words can add a personal touch in literature and creative works. It is essential to follow specific style guides for consistency and to consider cultural or contextual factors when making this choice.
