40 million people around the world use English as their second language, and many more are learning it. One common question that arises when writing in English is whether to use numbers or words to represent numerical values.
Writing Numbers
When writing, it is generally recommended to spell out numbers from one to ten, and use numerals for numbers greater than ten. However, there are some exceptions to this rule, such as when writing about time or dates.
Clarity in Writing
In the case of the number 30, both "30" and "thirty" can be used, depending on the context. In formal writing, such as academic or technical writing, numerals are often preferred for clarity and precision. On the other hand, in creative writing or informal writing, spelling out the number can add a touch of personality to the text. Ultimately, the choice between "30" and "thirty" depends on the style and tone of the writing, as well as the intended audience.

As a renowned author and educator, I have spent years studying and teaching the intricacies of the English language. Today, I would like to share my expertise with you on the topic "Should I write 30 or thirty?"
The question of whether to write numbers in words or digits is a common conundrum that many writers face. In the case of the number 30, the choice between writing "30" or "thirty" depends on various factors, including the context, style, and purpose of the writing.
In general, when writing numbers in formal or technical contexts, such as academic papers, scientific reports, or financial documents, it is recommended to use digits (e.g., 30). This is because digits are more concise and easier to read, especially when dealing with complex data or mathematical equations. Additionally, using digits helps to avoid confusion and ensures accuracy, as words can be misinterpreted or misspelled.
On the other hand, when writing in informal or creative contexts, such as fiction, poetry, or blog posts, it is often preferable to use words (e.g., thirty). This is because words can add a touch of personality and style to the writing, making it more engaging and readable. Furthermore, using words can help to create a more relaxed and conversational tone, which is suitable for informal writing.
However, there are some exceptions to these general guidelines. For instance, when writing numbers at the beginning of a sentence, it is usually recommended to use words (e.g., Thirty people attended the meeting). This is because starting a sentence with a digit can look awkward and may disrupt the flow of the text.
Another exception is when writing numbers in titles, headings, or captions. In these cases, it is often better to use digits (e.g., "30 Years of Service") to make the text more concise and attention-grabbing.
In conclusion, the choice between writing "30" or "thirty" depends on the specific context and purpose of the writing. As a general rule, use digits in formal or technical writing, and words in informal or creative writing. However, be mindful of exceptions, such as starting a sentence with a number or writing titles and headings. By following these guidelines, you can ensure that your writing is clear, concise, and effective.
As an expert in linguistics, I hope that this explanation has helped to clarify the topic "Should I write 30 or thirty?" Remember, the key to good writing is to be consistent, clear, and considerate of your audience. By choosing the right format for numbers, you can enhance the overall quality and readability of your writing.
