What is Universal Grammar?

If you are even slightly interested in language and linguistics, chances are you heard the term Universal Grammar a fair amount of times. It is a central concept in modern linguistics and the most controversial. It is a term that was born in the pursuit of trying to answer some very fundamental  and old questions related to language. But what exactly is Universal Grammar? 

Short version: 

Universal Grammar (UG) is, simply put, the idea that all human languages share the same fundamental principles. It’s mostly associated with Noam Chomsky, and is inseparable from the poverty of the stimulus argument and the innateness hypothesis.

Long version:

This idea is primarily borne out of observations made on first language acquisition research. See, our children acquire their native language(s) at a psychologically breakneck pace, which most linguists and psychologists generally agree on. Chomsky noted that children acquire linguistic features that their parents very rarely produce, if ever, and at a consistently rapid pace. He then argued that children somehow manage to pick up the full features of their native language(s) even though their parents usually never provide such a thorough input.

This argument suggested to Chomsky and his proponents that there must necessarily be a genetic/neurological component to first language acquisition. It makes sense; children acquire 90–95% of their native language(s) even though the input from their parents usually only ever provide 60–70% of the language (note: I’m just pulling numbers out of thin air here, but you get the idea). How is this possible? If you asked Chomsky, the logical answer is that there must be some sort of linguistic blueprint embedded in our genes, psychologically realized in our brains, and that basically our children are born already knowing the basic principles of human language, which are then completed with the help of the parents’ input. 

Chomksy goes further than that. He claims that said linguistic blueprint is universal, that the rules and principles contained in it is part of the human DNA and is thus shared by all members of our species, regardless of any ethnolinguistic differences. That linguistic blueprint is the most basic rules of grammar, of human language, and we are all born with it. It is only with the input from our parents (whom, of course, speak different languages) that children acquire different languages. But the fundamentals are all the same, they are universal. It is the universal grammar and it’s in all of us.

Or so Chomsky and his proponents would have you believe.

There are of course linguists who don’t buy into it this premise, and it was subjected to heavy scrutiny. Thus, over the years, more and more aspects of Chomsky’s proposed Universal Grammar have been falsified, and by this point UG’s claims have become so vague and abstract that it stops making any meaningful, testable sense, according to UG critics. They  that UG as a theory is indeed neat, but it’s a little too neat, and over the decades defending it has become more trial-and-error than anything else.

Maybe UG really does exist. Who knows, maybe in 50 years’ time we’ll have a clearer understanding of how the hell our children can acquire language at such blinding speeds, and it really is all because of a neurological linguistic blueprint inherent in our species. Or maybe it doesn’t. Or we may never know.

Thank you for reading this article, please share it if you think it deserves. I will see you in my next article, unitl then stay the nerd you are! 


  1. It amazes me that someone writing about language and grammar can't use "who" and "whom" properly.

    1. Maybe not everyone in this world is an English native speaker.

What can you do with a degree in linguistics?

People so often assume that a linguist's job is to learn as many languages as possible, when in actuality it is not anything near that. So, let us put an end to this erroneous assumption once and for all. 
Linguists do not engage in learning languages, linguists engage in studying how language works. And when I say language, I mean human language, an umbrella term that subsumes all languages spoken by humans, including pidgins, creoles, and sign languages. Thanks to linguists the world is a better place now, many daunting problems that existed for centuries have been solved because now we have a better understanding of language and language-related issues. in this article, you will see, in full-length, the contributions of linguists to the modern world. And you are going to see that it's a disgrace to confine a linguist's job to just learning languages. 
Let me just give you some examples before we break things down in more detail. A linguist's job could involve explo…

What linguists know that other people don't.

Studying languages is a privilege. When you analyze language and everyday speech you start to realize that there is an astonishing amount of wonder in this system that we take for granted. Linguists questioned the obvious, which is language, and got answers that forever changed mankind’s understanding of Language and human nature. In this article, you will see what linguists know that is not so evident to other people. So let's see what we've got. We all speak one language. One of the main discoveries of modern linguistics is that it made us aware that all the languages we speak are similar in astonishing respects; they manifest the same pattern, follow the same rules, they are learnt in exactly the same way, and that all the differences are only superficial. So, in a sense we all speak the same language. This was captured by Chomsky in an excellent metaphor in an excellent book of his titled Language and Mind in which he says that if a Martian scientist, somebody with a diffe…

8 books everyone into linguistics should read.

When you want to decide on what to read in language and linguistics, it is never easy to pick a reading list; there is just so many books out there under the label of linguistics, especially that publications in linguistics have been growing like wild fire in the last couple of decades. So with your limited time and the unlimited number of books, it is always wise to make some research beforehand on what exactly you want to read. There is a lot to choose from, and the best book will depend on what you are specifically interested in. This is why we, at The Language Nerds, compiled a list of linguistics books that will entertain the novice and the expert alike. Here are some places to start: 

1.The Language Instinct by Steven Pinker

This is a book for the general science readers, it is very accessible whether you have a background in linguistics or not. It is considered by many as a landmark in linguistics. It is a great introduction and primer to some of the more basic problems and que…
