Are you confused about the difference between reasonability and reasonableness? You’re not alone. These two words are often used interchangeably, but there is a subtle difference between them that can make all the difference in your writing.
Let’s clear up which of the two is the proper word. The correct word is “reasonableness.” However, “reasonability” is also a valid word, but it is less common and not as widely accepted.
So, what do these words mean exactly? Reasonableness refers to the quality of being reasonable, fair, and justifiable. It is the state of being in accordance with reason or logic. Reasonability, on the other hand, refers to the quality of being reasonable or rational. It is the ability to make judgments based on reason rather than emotion or prejudice.
Throughout this article, we will explore the difference between reasonability and reasonableness in more detail and discuss why it is important to use the correct word in your writing.
Define Reasonability
Reasonability is a term that is often used in legal and business contexts to refer to the quality of being reasonable or rational. It is the state of being able to make logical decisions based on sound judgment and objective analysis. Reasonability is often associated with fairness, impartiality, and common sense, and it is an important concept in many areas of law, including contract law, tort law, and criminal law.
In legal terms, reasonability refers to the standard of conduct that is expected of a person in a particular situation. This standard is often based on what a reasonable person would do in the same circumstances. For example, in a negligence case, a defendant may be held liable if their conduct falls below the standard of care that a reasonable person would exercise in the same situation.
Define Reasonableness
Reasonableness is a related concept to reasonability, but it has a slightly different meaning. Reasonableness refers to the quality of being reasonable or rational, but it also implies a sense of proportionality and fairness. A decision or action that is reasonable is one that is appropriate and justifiable in the circumstances.
In legal terms, reasonableness is often used to evaluate the validity of a particular decision or action. For example, in administrative law, a decision made by a government agency may be subject to judicial review to determine whether it was reasonable in the circumstances. A decision that is found to be unreasonable may be overturned by the court.
Overall, reasonableness is a broader concept than reasonability, as it encompasses not only the ability to make logical decisions based on sound judgment, but also the sense of fairness and proportionality that is necessary to ensure that decisions and actions are justifiable in the circumstances.
How To Properly Use The Words In A Sentence
Choosing the right word in a sentence can be the difference between sounding knowledgeable and sounding uneducated. The words reasonability and reasonableness are often used interchangeably, but they have different meanings and should be used correctly to convey the intended message.

Common Mistakes To Avoid
When it comes to using reasonability and reasonableness, there are several common mistakes that people make. These mistakes can lead to confusion and misunderstandings, so it’s important to be aware of them and avoid them whenever possible.
Using Reasonability And Reasonableness Interchangeably
One of the most common mistakes people make is using reasonability and reasonableness interchangeably. While these words may seem similar, they have different meanings and uses.
| Word | Meaning | Usage |

- When in doubt, consult a dictionary or thesaurus to ensure you are using the correct word
By following these tips, you can avoid common mistakes and ensure that your communication is clear and effective.
Context Matters
When it comes to choosing between reasonability and reasonableness, context is key. Depending on the situation, one of these terms may be more appropriate than the other.
Examples Of Different Contexts
Let’s take a look at some different scenarios where the choice between reasonability and reasonableness might change:
Legal Context
In a legal context, reasonableness is often used to determine whether someone’s actions were justified. For example, a police officer’s use of force may be deemed reasonable if it was necessary to protect themselves or others. On the other hand, reasonability is often used in contract law to determine whether a certain clause or requirement is reasonable given the circumstances.
Business Context
In a business context, reasonability is often used to determine whether a certain decision or action is reasonable given the company’s goals and resources. For example, a company may decide that it is not reasonable to invest in a new product line if the potential profits do not outweigh the costs. Reasonableness, on the other hand, may be used in negotiations between two companies to determine a fair price for goods or services.
Personal Context
In a personal context, both reasonability and reasonableness may come into play. For example, someone may decide that it is not reasonable to spend a large amount of money on a luxury item, but it may be reasonable for them to do so if it brings them joy and they can afford it. Reasonability may also be used in personal relationships to determine whether someone’s expectations or demands are reasonable given the circumstances.
Overall, the choice between reasonability and reasonableness depends on the specific context in which they are used. It is important to consider the situation and choose the term that best fits the circumstances.
Exceptions To The Rules
While the rules for using reasonability and reasonableness are generally straightforward, there are some exceptions where they may not apply. In these cases, it is important to understand the reasoning behind the exceptions and how they affect the use of these terms.
Legal Exceptions
One exception to the rules for using reasonability and reasonableness is in a legal context. In legal language, reasonability is often used to refer to a standard of behavior or action that is expected of someone in a given situation. This standard is often determined by a court or other legal authority based on the circumstances of the case.
For example, in a negligence case, a court may determine that a defendant’s conduct was not reasonable given the circumstances. In this case, the court is using reasonability to establish a standard of behavior that the defendant failed to meet.
On the other hand, reasonableness is often used in legal language to refer to a requirement that a contract or other legal agreement be fair and equitable to both parties. In this context, reasonableness is often determined by the court based on the specific terms of the agreement and the circumstances surrounding its formation.
Idiomatic Expressions
Another exception to the rules for using reasonability and reasonableness is in the use of idiomatic expressions. Idioms are phrases that have a figurative meaning that is different from their literal meaning. In some cases, idiomatic expressions may use either reasonability or reasonableness, depending on the specific context.
For example, the phrase “beyond all reason” is an idiomatic expression that means something is completely unreasonable or irrational. In this case, reasonability would not be appropriate because the phrase is not referring to a standard of behavior or action. Instead, reasonableness would be more appropriate because it is referring to the concept of something being rational or reasonable.
Technical Jargon
Finally, an exception to the rules for using reasonability and reasonableness is in the use of technical jargon. In some specialized fields, such as engineering or medicine, these terms may have specific meanings that differ from their common usage.
For example, in engineering, reasonability may be used to refer to a measurement of the accuracy of a mathematical model or simulation. In this case, reasonability is being used as a technical term with a specific meaning that is different from its common usage.
Similarly, in medicine, reasonableness may be used to refer to a standard of care that is expected of a healthcare provider. In this context, reasonableness is being used as a technical term that has a specific meaning within the medical field.
| Exception | Explanation | Example |
|---|---|---|
| Legal | Reasonability used to establish a standard of behavior or action; reasonableness used to refer to a fair and equitable contract or agreement | A court determines that a defendant’s conduct was not reasonable given the circumstances |
| Idiomatic Expressions | Idioms may use either reasonability or reasonableness, depending on the specific context | The phrase “beyond all reason” means something is completely unreasonable or irrational |
| Technical Jargon | Reasonability and reasonableness may have specific meanings in specialized fields, such as engineering or medicine | Reasonability used to refer to a measurement of the accuracy of a mathematical model or simulation in engineering |
Practice Exercises
To improve your understanding and use of reasonability and reasonableness in sentences, here are some practice exercises:
Exercise 1: Fill In The Blank
| Sentence | Answer |
|---|---|
| The __________ of the request was questionable. | reasonability |
| The judge determined that the terms of the contract were __________. | reasonable |
| It is not __________ to expect someone to work 60 hours a week without overtime pay. | reasonable |
| The __________ of the argument was difficult to follow. | reasonableness |
Explanation: In the first sentence, we use “reasonability” because we are questioning the validity or soundness of the request. In the second sentence, we use “reasonable” because we are describing the terms of a contract as fair or rational. In the third sentence, we use “reasonable” because we are discussing a fair or rational expectation. In the fourth sentence, we use “reasonableness” because we are describing the quality of the argument as logical or sensible.
Exercise 2: Rewrite The Sentence
- Original sentence: The reasonability of the proposal was debatable.
- Rewritten sentence: There was debate over whether the proposal was reasonable.
- Rewritten sentence: The opposition questioned the fairness of the decision.
- Rewritten sentence: It is unfair to expect employees to work overtime without pay.
- Rewritten sentence: The argument was clearly logical and sensible to everyone who heard it.
Explanation: In each of these sentences, we are rewriting the sentence to use a different form of “reasonability” or “reasonableness” to demonstrate how the words can be used interchangeably. In some cases, we are also using synonyms to show how the meaning of the sentence remains the same even when the specific word choice changes.
By practicing these exercises, you can improve your understanding and use of reasonability and reasonableness in your writing and conversations.
