In writing, small details like punctuation, grammar, and even word choices can make a huge difference. One common point of confusion for writers is either to use “long term” or “long-term”. Understanding the differences between these forms isn’t just about adhering to grammar rules; it’s about improving clarity, flow, and precision in your writing.

So, it is hyphenated, or should you leave the space? Let’s dive into the depth guide to settle the confusion once and for all.

Why Is There Confusion?

The confusion between “long term” and “long-term” comes from the dual nature of these words in the English language. They can function as both nouns and adjectives, depending on how they’re used in a sentence. English speakers often mix them up because the difference seems sub ttitle—sometimes even unimportant—but using them incorrectly can lead to awkward or unclear and justifiable  sentences.

Moreover, English grammar has quite a few exceptions and idiosyncrasies, and hyphenated phrases can be tricky. While some hyphenated words evolve into single words over time (like “email” from “e-mail”), others, as “long-term,” hold onto the hyphen to maintain their specific function in a sentence.

Let’s break down exactly what actually means, when to use them, and how to avoid common pitfalls.

What Does “Long Term” (with space) Mean?

Without the hyphen is typically a noun phrase. It refers to an extended period of time. If you’re talking about something that will happen over so many years, decades, or even lifetimes, then you’re likely talking about it.

Usage of “Long Term” as a Noun Phrase:

In this context, it is used as a subject or object in a sentence, indicating the duration or scope of time.

Examples:

• Investing for the long term can lead to higher returns.
• The company is focused on the long term rather than short-term profits.
• These changes will benefit the environment in the long term.

Here, “long term” stands alone as a concept. It’s not describing something else; rather, it’s a noun phrase that represents a long period of time. You can easily recognize when to use the two-word version by checking if “long term” is the subject or object of your sentence.

Formal and Informal Use:

“Long term” as a noun phrase is commonly found in both formal and informal writing. It’s often used in the context of business, finance, health, and strategic planning.

 Example:

• In finance, you’ll frequently hear about “long term” investments or “long term” growth.
• In healthcare, doctors might discuss long term treatment plans for chronic illnesses.

What Does “Long-Term” (Hyphenated) Means?

On the other hand “long-term” with a hyphen is an adjective. It describes a noun, giving more information about the duration related to that noun.

Usage of “Long-Term” as an Adjective:

When “long-term” is used as an adjective, it directly modifies a noun and helps the reader understand the timescale or duration of the noun being described.

For examples:

• We need a long-term solution to this problem.
• She’s involved in a long-term project that could take years to complete.
• Long-term planning is essential for success in business.

Here, the hyphenated version comes before the noun (solution, planning) and acts as a descriptive word. The hyphen is necessary to clarify that it’s not just “long” or “term” alone that describes the noun, but rather the combined concept of “long-term”.

Quick Test for Writers:
