The Core Difference Between Can Not or Cannot

Let’s break down this grammar puzzle. The difference between “can not” and “cannot” is subtle, yet significant. “Cannot” functions as a single word, expressing inability or impossibility. For example, “I cannot believe it” shows disbelief.

On the other hand, “can not” is two words, where “can” is a verb and “not” is an adverb modifying it. This form is used when “not” modifies a specific part of the verb phrase following “can.” For instance, “I can not only sing, but also dance” emphasizes two distinct abilities.

To clarify, think of it this way: “cannot” is like a solid brick wall—an absolute barrier. Conversely, “can not” is more like a gate that can be opened or closed, depending on the context. So, “cannot” expresses a general inability. While “can not” highlights a specific exception or alternative.

In short, “cannot” is the standard form for expressing inability. “Can not” is less common and usually emphasizes something else in the sentence. Therefore, in most cases, “cannot” is the safer and more concise choice.

Examples: Seeing is Believing

Let’s solidify the difference with some clear examples. Seeing these in action will make the distinction crystal clear.

Cannot (General Inability): “She cannot attend the meeting due to a prior commitment.” This sentence states a simple inability. There are no exceptions or alternative actions mentioned. In other words, attending the meeting is impossible for her.
Can Not (Emphasis on Alternative Action): “She can not attend the meeting in person, but she can join via video conference.” Here, the emphasis shifts. While physical attendance is impossible, another option exists. Therefore, “can not” highlights the contrast between these possibilities.
Cannot (Simple Denial): “I cannot understand why he would do that.” This expresses disbelief or a lack of comprehension. In short, it’s a straightforward statement of not understanding.
Can Not (Emphasis on a Specific Part of the Verb): “They can not only build houses, but they can also design them.” The focus is on the two different actions they are capable of. Thus, can not is used to set up the contrast between these two skills.

To sum up, “cannot” is your go-to for expressing a simple inability. Use “can not” when you want to emphasize an alternative or contrast specific actions. For example, if you are unsure, using cannot is usually the correct choice.

When to Use “Can’t” (The Contraction)

Now, let’s talk about “can’t.” This little word is simply a contraction of “cannot.” In other words, it’s a shorter, more casual way of saying the same thing. Therefore, you’ll primarily find “can’t” in informal writing and spoken language.

Informal Writing: Think emails to friends, text messages, or casual blog posts. For instance, “I can’t believe you did that” is perfectly fine in a message to a friend.
Spoken Language: “Can’t” is incredibly common in everyday conversation. For example, “I can’t go to the party tonight” is a natural way to decline an invitation.

However, avoid “can’t” in formal writing, such as academic papers, business reports, or official documents. In these settings, stick with the full “cannot.” To clarify, using “cannot” in formal contexts maintains a professional and polished tone.

Pro Tip: If you’re unsure whether your writing style is formal or informal, err on the side of caution and use “cannot.” This way, you avoid any potential missteps. So, when in doubt, spell it out.
