Prescriptive vs Descriptive Grammar – Grammar Check
What are the differences between prescriptive and descriptive grammar? And why does it matter? It is all too common for people to confuse descriptive and prescriptive grammars. In this article, we’ll explore the pros and cons of each type of grammar, and give you some tips on how to use them both effectively.

Descriptive and prescriptive grammarians alike have their own opinions of what proper grammar is. Let’s review exactly what makes these grammatical forms so different.
Descriptive grammar is the study of how language is actually used by speakers and writers.
This type of grammar focuses on the rules that are actually followed by native speakers, rather than prescriptive rules that may be found in a textbook.
For example:
Descriptive grammar would note that many people use the word “ain’t” in informal speech, even though it is not considered proper English. They might also say “anyways” instead of “anyway or use their own form of “goodnight”.
While prescriptive grammarians may criticize this usage, a descriptive grammarian would simply describe it as a common phenomenon.
Remember, it is NOT spelled grammer! We are talking about descriptive grammar with an -AR!
Takeaway: Descriptive grammar is more concerned with describing how language is used, rather than prescribing how it should be used.
Some people believe that if you don’t follow the rules of grammar, you won’t be taken seriously. This is the belief of prescriptive grammarians. It is a more formal type of communication.
Prescriptive grammar tells you what you should do, rather than what people actually do.
For example:
Prescriptive grammar would say that you should always use proper punctuation (like how to hyphenate “in-person”), and that you shouldn’t start a sentence with a conjunction. The formal rules around using the 8 parts of speech also follow prescriptive grammar guidelines.
- Of course, there are exceptions to every rule, but in general, prescriptive grammar is all about following the rules.
Takeaway: Prescriptive grammar focuses primarily on standard forms of grammar and syntactic constructions. While descriptive grammar doesn’t always play by the rules.
Now you know the definitions of these grammatical constructions. Let’s dive into some of the key differences that make these forms of grammar unique.

Descriptive grammar understands that different people speak and write differently. They do not focus on what is traditionally considered “correct” and “incorrect grammar.” Prescriptive grammar takes the principle that the language usage of native speakers is correct.
For example, look at the words re-use or reuse. The correct spelling is reuse, but some groups of people may choose to add the hyphen. This would be prescriptive grammar!
Prescriptive grammar sticks to a set of standardized rules. Prescriptive grammarians follow a specific set of rules. However, descriptive grammar does not follow a set of standard rules. The rules can vary based on how native speakers communicate. If you want to make sure you followed prescriptive grammar rules correctly in your sentences, try out our complete sentence checker tool.

Examples of prescriptive grammar include:
- Never split an infinitive
- Don’t end a sentence in a preposition
- Always use who when referring to a person
While some of these rules may make sense, others are outdated. Take the grammar rules for have had vs had had. For one thing, they can be difficult to follow- especially when you’re speaking spontaneously.
If you want to see some examples of descriptive grammar in action, just take a look at how people use the word ain’t.
Ain’t is technically a contraction of am not, is not, are not, or has not. However, in practice, it is often used as a catch-all negative word, regardless of the verb tense.
For example:
- You might hear someone say “I ain’t going to do that” or “She ain’t got no sense.”
Here is a list of the pros of using prescriptive grammar.
- Standardization, which provides a common set of rules and conventions for language usage. This standardization helps to establish clarity and consistency in communication, ensuring that people can understand each other effectively. P
- Promotes adherence to established language norms, allowing for a shared understanding among speakers and writers.
Here is a list of the main disadvantages of prescriptive grammar.
- Potential failure to reflect natural language usage and variation. Language is a dynamic and ever-changing system, influenced by factors such as region, culture, and social context.
- Can cause a disconnect between prescribed rules and actual language usage, potentially resulting in misunderstandings or exclusions.
- Can hinder creativity and language development.
Here is a list of the main advantages of using descriptive grammar rules.
- More accurately reflects natural language usage and variation.
- Better at capturing the dynamic nature of language, accounting for regional, cultural, and social differences in usage.
- Is a more inclusive understanding of language, recognizing and valuing the richness and complexity of linguistic diversity.
Here is a list of the main problems with using descriptive grammar rules.
- Too much ambiguity and lack of standardization.
- Can cause too many differing interpretations or preferences among speakers, which may hinder effective communication and cause confusion.
- The lack of standardized rules can make it challenging for learners to grasp and internalize language structures and conventions.
Q: What are the similarities between prescriptive and descriptive grammar?
There are no similarities between prescriptive and descriptive grammar. However, both are forms of grammar, and both have rules that govern how language is used. However, prescriptive grammar is based on the idea that there are “correct” ways to use language, while descriptive grammar simply observes how language is actually used.
Q: Why are descriptive and prescriptive grammar important?
Descriptive and prescriptive grammar is important because it helps people use formal English speech and writing. It also enables people to clearly and effectively communicate their thoughts and ideas. In addition, proper grammar usage makes it easier for others to understand what you’re trying to say.
Q: What is descriptive and prescriptive grammar examples?
Descriptive grammar is a record of the language as it is actually used by native speakers. In contrast, prescriptive grammar is a set of rules for how the language should be used.Here are some examples to illustrate the difference between descriptive and prescriptive grammar:
Descriptive: The pronoun “I” is always capitalized in English.
Prescriptive: You should always capitalize the pronoun “I” in English
