In the world of writing, small details can make a big difference, and one such detail is whether to use “pre-existing or preexisting.” This seemingly minor choice can leave writers puzzled, wondering which form is correct. In this article, we’ll explore the usage of “pre-existing” vs “preexisting,” providing clear guidelines to help you make the right decision in your writing.
Why is there Confusion?
The confusion between “pre-existing” and “preexisting” stems from the way compound words are formed in English. Compound words can be written in three ways: open (with a space, like “ice cream”), hyphenated (with a hyphen, like “mother-in-law”), or closed (without a space or hyphen, like “notebook”). The transition from hyphenated to closed compounds often happens over time as words become more commonly used, but this process is not always straightforward or consistent.
In the case of “pre-existing” and “preexisting,” the hyphenated form was traditionally more common. However, as language evolves and writers seek simplicity, the closed form “preexisting” has gained popularity. This shift has led to uncertainty about which form is currently correct. To add to the confusion, different style guides and dictionaries may have varying preferences, making it challenging for writers to know which version to use.
What do ‘Pre-Existing’ or ‘Preexisting’ Mean?
The terms “pre-existing” and “preexisting” essentially mean the same thing. Both refer to something that existed or was present before a certain point in time. The prefix “pre-“ means “before,” and when combined with “existing,” it indicates that something was already in existence prior to a specified event or condition.
For example, in the context of software development, a “pre-existing” or “preexisting” bug refers to a defect in the software that existed before the latest update or release. Similarly, in real estate, a “pre-existing” structure is one that was built before current regulations or standards were put into place.
“Pre-Existing” or “Preexisting”: Which One Should Be Used?
Choosing between “pre-existing” and “preexisting” often depends on the style guide you are following or your personal preference. Different contexts may favor one form over the other, so it’s helpful to know the conventions associated with each.
-
Style Guides and Consistency:
- The Chicago Manual of Style generally recommends the closed form “preexisting” for compounds with prefixes, unless the resulting word is confusing or hard to read.
- The Associated Press (AP) Stylebook tends to favor hyphenated forms like “pre-existing,” especially in journalistic writing, to ensure clarity.
-
Readability and Clarity:
- Some writers prefer “pre-existing” because the hyphen makes the word easier to read, particularly in complex sentences where clarity is crucial.
- Others lean towards “preexisting” for a cleaner, more streamlined look, especially in informal writing or contexts where space is limited, such as in headlines.
-
Audience and Context:
- Consider your audience and the context in which you’re writing. If you’re writing for a formal publication or academic paper, following the preferred style guide is important.
- In contrast, for personal blogs or casual writing, either form can be acceptable as long as you remain consistent throughout your text.
Ultimately, the decision between “pre-existing” and “preexisting” is about ensuring your writing is clear and consistent. Understanding the preferences of your audience and the standards of your chosen style guide will help you make the best choice.
What About Pre Existing with Space?
“Pre existing,” written with a space, is generally less preferred and can be considered incorrect in formal writing. Most style guides recommend using either the hyphenated “pre-existing” or the closed “preexisting” to ensure clarity and consistency based on your stylistic preference and the guidelines you are following. So, avoid “pre existing” to maintain standard English language practices.

Origins of the Word “Pre-Existing” or “Preexisting”
The terms “pre-existing” and “preexisting” trace their origins to the late 16th century. Derived from the prefix “pre-” meaning “before,” and “exist,” they signify something that exists beforehand. Originally, compound words like “pre-existing” were typically hyphenated to clarify their components and meaning. This convention ensured clear communication in written English. Over time, especially in the mid-20th century, the medical insurance industry adopted the term “pre-existing condition” to denote a health issue already present before obtaining coverage, formally documented since 1942. The evolution from hyphenated to closed forms, such as “preexisting,” mirrors broader trends in English language usage toward simplicity and efficiency in expression.
