Definition of Adverbs of Certainty
Adverbs of certainty, also known as adverbs of assurance or epistemic adverbs, are words that express the speaker’s or writer’s degree of belief or confidence in the truth of a statement. They indicate how sure someone is about something. These adverbs modify the entire sentence or clause, rather than a specific verb, adjective, or other adverb. Understanding adverbs of certainty is crucial for conveying precision and clarity in communication. They allow you to express your level of confidence, ranging from absolute certainty to mere possibility.
In essence, adverbs of certainty function as modal adverbs, providing information about the speaker’s perspective on the truth value of the proposition being expressed. They help the listener or reader understand the speaker’s stance and interpret the message accordingly. The accurate and effective use of these adverbs can significantly enhance the credibility and persuasiveness of your communication.
For example, consider the difference between saying “It will rain tomorrow” and “It will certainly rain tomorrow.” The addition of “certainly” adds a strong degree of confidence to the prediction. Similarly, “It might rain tomorrow” conveys a much lower level of certainty. By using these adverbs thoughtfully, you can fine-tune your message to reflect your actual level of belief.
Structural Breakdown
Structurally, adverbs of certainty typically modify the entire clause or sentence. They don’t usually modify a specific verb or adjective. Their placement in the sentence can vary, but they often appear at the beginning, middle (before the main verb), or end of the clause. The specific placement can sometimes influence the emphasis of the statement. For instance, placing an adverb of certainty at the beginning of a sentence can draw more attention to the speaker’s confidence level.
The position of the adverb can subtly change the nuance of the sentence. When placed at the beginning, it emphasizes the degree of certainty. In the middle, it integrates more smoothly into the flow of the sentence. At the end, it can serve as a concluding remark that reinforces the speaker’s confidence.
Consider these examples:
- Certainly, it is a good idea. (Emphasis on certainty)
- It is certainly a good idea. (Neutral placement)
- It is a good idea, certainly. (Reinforcement of certainty)
Understanding the structural flexibility of these adverbs allows you to use them strategically to convey your intended meaning with greater precision and impact. Experimenting with different placements can help you develop a feel for the subtle nuances they create.
Types and Categories of Adverbs of Certainty
Adverbs of certainty can be categorized based on the degree of confidence they express. Here are three main categories:
Adverbs of Positive Certainty
These adverbs indicate a very high degree of confidence, suggesting that the speaker is almost completely sure of the statement’s truth. They leave little to no room for doubt.
Examples include: certainly, definitely, absolutely, undoubtedly, assuredly, positively, unquestionably, undeniably, clearly, obviously, plainly, indeed, really, truly, for sure.
Adverbs of Near Certainty
These adverbs express a strong belief, but with a slightly lower degree of confidence than adverbs of positive certainty. They suggest a high probability, but acknowledge a small possibility of error.
Examples include: probably, likely, presumably, apparently, evidently, seemingly, conceivably, quite.
Adverbs of Possible Certainty
These adverbs indicate a lower degree of confidence, suggesting that the speaker believes the statement is possible, but not necessarily probable. They express a sense of possibility or speculation.
Examples include: maybe, perhaps, possibly, arguably, theoretically, allegedly, purportedly.
Examples of Adverbs of Certainty
To further illustrate the use of adverbs of certainty, let’s examine examples within each category.

Usage Rules for Adverbs of Certainty
Using adverbs of certainty correctly requires understanding their placement in sentences, distinguishing between formal and informal usage, and knowing how to combine them effectively.
Placement in Sentences
The placement of adverbs of certainty can affect the emphasis and nuance of a sentence. While they can generally appear at the beginning, middle, or end of a clause, certain positions are more common or appropriate depending on the desired effect.
- Beginning: Emphasizes the degree of certainty. Example: Certainly, I will help you.
- Middle (before the main verb): Integrates smoothly into the sentence. Example: I will certainly help you.
- End: Reinforces the certainty. Example: I will help you, certainly.
Note that some adverbs, like “maybe” and “perhaps,” are almost always placed at the beginning of the sentence.
Formal vs. Informal Usage
Some adverbs of certainty are more appropriate for formal writing and speech, while others are better suited for informal contexts. For example, “assuredly” and “undoubtedly” are more formal than “for sure” or “really.”
Formal: Assuredly, the results will be analyzed thoroughly.
Informal: For sure, we’ll get it done.
Choosing the right adverb for the context is crucial for maintaining the appropriate tone and register.
Combining Adverbs of Certainty
While it is possible to combine adverbs of certainty, it should be done with caution, as it can sometimes sound redundant or awkward. If you do combine them, ensure that they complement each other and enhance the overall meaning.
Acceptable: “Almost certainly” (combines “almost” with “certainly” to express a high degree of probability).
Less Acceptable: “Certainly definitely” (redundant, as both adverbs express a very high degree of certainty).
It’s generally best to use a single, well-chosen adverb of certainty to convey your intended meaning effectively.
Common Mistakes with Adverbs of Certainty
Several common mistakes can occur when using adverbs of certainty. Being aware of these errors can help you avoid them and improve the accuracy of your language.
| Mistake | Incorrect Example | Correct Example | Explanation |
|---|---|---|---|
| Redundancy | She will certainly definitely arrive on time. | She will definitely arrive on time. | Avoid using multiple adverbs with similar meanings. |
| Incorrect Placement | Maybe she is coming. | Maybe, she is coming. | Some adverbs have preferred positions in the sentence. |
| Inappropriate Formality | For sure, we will analyze the data thoroughly. | Assuredly, we will analyze the data thoroughly. | Use adverbs that match the context’s formality. |
| Overuse | Certainly, I think that certainly, it is a good idea and certainly, we should do it. | I think it is a good idea, and we should do it. | Avoid using adverbs of certainty excessively. |
| Misunderstanding Degree of Certainty | It is possibly going to rain, so I’m sure it will. | It is possibly going to rain, so I’ll bring an umbrella just in case. | Ensure the adverb matches the level of confidence. |
By being mindful of these common mistakes, you can use adverbs of certainty more effectively and accurately.

- This is undeniably the best solution. (Strong endorsement)
- He is truly a remarkable person. (Strong admiration)
Using adverbs of certainty emphatically can add power and conviction to your communication, but it’s important to use them judiciously to avoid sounding overly dramatic or insincere.
Frequently Asked Questions
Here are some frequently asked questions about adverbs of certainty:
- What is the difference between “probably” and “possibly”?
“Probably” indicates a higher degree of likelihood than “possibly.” If something is “probable,” it is more likely to happen than not. If something is “possible,” it simply means that it could happen, but there’s no strong indication that it will.
- Can I use multiple adverbs of certainty in one sentence?
While grammatically possible, it’s generally best to avoid using multiple adverbs of certainty in the same sentence, as it can sound redundant or awkward. Choose the single adverb that best expresses your intended meaning.
- Where is the best position to place an adverb of certainty in a sentence?
The placement depends on the desired emphasis. Beginning placement emphasizes the certainty itself, middle placement integrates the adverb smoothly, and end placement reinforces the certainty.
- Are some adverbs of certainty more formal than others?
Yes, some adverbs like “assuredly” and “undoubtedly” are more formal, while others like “for sure” and “really” are more informal. Choose the adverb that matches the context and tone of your communication.
- How do adverbs of certainty interact with modal verbs?
Adverbs of certainty can modify modal verbs to express varying degrees of possibility, probability, and necessity. For example, “He certainly must be tired” expresses a stronger belief than “He might be tired.”
- What is the difference between ‘surely’ and ‘certainly’?
‘Surely’ is often used to express surprise or disbelief, or to seek confirmation, whereas ‘certainly’ expresses a strong degree of confidence or assurance. For example: “Surely, you didn’t believe that!” (surprise) vs. “I will certainly be there.” (assurance). ‘Surely’ can also imply expectation, as in ‘Surely, he’ll arrive soon’.
- Is it correct to say “most certainly”?
Yes, “most certainly” is a valid and emphatic way to express a very high degree of certainty. It’s stronger than simply saying “certainly.”
- How can I improve my use of adverbs of certainty in my writing?
Pay attention to the context and your intended meaning. Consider the degree of confidence you want to convey. Read widely and notice how skilled writers use these adverbs. Practice writing and speaking, and seek feedback on your usage.
