At first glance, it looks like a typo. Perhaps a copy-paste error where a writer fell asleep on the keyboard, or a software glitch echoing a single word into infinity. It reads:
“Buffalo buffalo Buffalo buffalo buffalo buffalo Buffalo buffalo.”
Eight identical words. No punctuation other than the period at the end. To the average reader, it is nonsense. To a linguist, however, it is a thing of beauty. This sentence is one of the most famous examples of distinct lexical ambiguity and syntactical flexibility in the English language. It is grammatically correct, semantically meaningful, and practically impossible to understand without a guide.
Welcome to the extreme edge of English grammar, where we explore how homonyms and reduced relative clauses can turn a single word into a complex narrative about bullying bison in upstate New York.
The Three Faces of “Buffalo”
To decode the sentence, we must first acknowledge that English is a language that loves to recycle. We use the same sounds and spellings for entirely different meanings. In linguistics, these are called homonyms. To make the eight-word sentence work, we utilize three distinct meanings of the word “buffalo”:
- The Proper Noun (Adjective): This refers to the city of Buffalo, New York. In English, we often use proper nouns attributively (like an adjective) to designate origin. Just as you might say “London fog” or “California wine”, you can say “Buffalo buffalo” to assert that the animal comes from that specific city.
- The Noun (Animal): The American bison. While scientifically distinct from the water buffalos of Asia or Africa, in common North American parlance, we call them buffalo.
- The Verb (Action): Here is the secret ingredient. To “buffalo” someone means to bully, intimidate, deceive, or bamboozle them. It is a slang term dating back to the 19th century, but it is a valid transitive verb.
Once you understand that the word represents a specific place, a specific animal, and a specific act of aggression, the sentence begins to unclench its fist.
Substitution: The Rosetta Stone Strategy
The easiest way to parse the sentence structure is to replace “Buffalo” with synonyms that don’t sound alike. Let’s swap the words as follows:
- The City: replace with Boston
- The Animal: replace with bison
- The Verb: replace with confuse
If we strictly swap the words in the original sentence (“Buffalo buffalo Buffalo buffalo buffalo buffalo Buffalo buffalo”), we get this structure:
“Boston bison Boston bison confuse confuse Boston bison.”
This is clearer, but it still sounds a bit clunky. Why? Because of a specific grammatical feature known as the reduced relative clause.
The Invisible Glue: Reduced Relative Clauses
English grammar allows us to omit relative pronouns—words like “that”, “which”, or “who”—when they function as the object of a relative clause. This is why you can say “The book I read” instead of “The book that I read.” Both are correct, but the first one is a reduced relative clause.
In the Buffalo sentence, there is an invisible “that” hiding between the second and third words.
Let’s look at our substitution sentence again: “Boston bison [that] Boston bison confuse, confuse Boston bison.”
If we expand it fully into standard, comfortable English, it means:
“The bison from Boston, who are confused by other bison from Boston, also confuse the bison from Boston.”
Parsing the Sentence: Word by Word
Now that we have the theory, let’s conduct a linguistic autopsy on the original eight words. Here is the role of every single “Buffalo” in the sequence:
- Buffalo (Proper Noun/Adjective): Identifies the city of origin for the first group of animals.
- Buffalo (Noun/Subject): The animals themselves. These are the protagonists of our sentence.
- Buffalo (Proper Noun/Adjective): Identifies the city of origin for the second group of animals (the bullies).
- Buffalo (Noun/Subject of Relative Clause): The animals that are doing the bullying in the description clause.
- Buffalo (Verb/Action in Relative Clause): The act of bullying. Meaning: “The bison (2) that the bison (4) bully (5)…”
- Buffalo (Main Verb): The main action of the sentence. The first group of bison are now acting out.
- Buffalo (Proper Noun/Adjective): Identifies the city of origin for the victim group.
- Buffalo (Noun/Direct Object): The victims of the main action.
So, the narrative is: NY Bison [whom other] NY Bison bully, [themselves] bully NY Bison.
It is a commentary on the cycle of violence in the animal kingdom of upstate New York.
Why Is This Important for Language Learners?
You might wonder why linguists obsess over a sentence that no sane person would ever speak in casual conversation. The Buffalo sentence serves as a fascinating stress test for the rules of syntax.
1. Structural Ambiguity
Computers struggle with sentences like this, and so do humans. It highlights how much we rely on context, intonation, and varying vocabulary to convey meaning. When lexical variety is removed, our brains have to work overtime to parse the syntax (word order).
2. The Hierarchy of Constituents
This sentence teaches us about “constituents”—the natural groupings of words. “Buffalo buffalo” (the City + the Animal) creates a Noun Phrase. The sentence shows how English allows us to nest Noun Phrases inside other phrases recursively without losing grammatical validity.
3. Semantic Satiation
Reading this post, you have likely experienced “semantic satiation.” This is a psychological phenomenon where repetition causes a word or phrase to temporarily lose meaning to the listener, who then perceives the speech as repeated meaningless sounds. By the time you read the word “buffalo” for the thirtieth time, it starts to look like a bizarre alien symbol rather than a word.
Other Linguistic Oddities
Buffalo isn’t the only word that allows for this kind of gymnastics, though it is the most famous. Another popular example involves the past perfect tense.
Consider a student named James who is taking a test on punctuation. He writes a sentence using the phrase “had had”, while his classmate John uses just “had.” The teacher prefers James’s answer.
We can describe this situation with this grammatically correct sentence:
“James while John had had had had had had had had had had had a better effect on the teacher.”
With punctuation added, it becomes intelligible: “James, while John had had ‘had’, had had ‘had had’; ‘had had’ had had a better effect on the teacher.”
Conclusion
“Buffalo buffalo Buffalo buffalo buffalo buffalo Buffalo buffalo” was first popularized by William J. Rapaport, a professor at the University at Buffalo (fittingly), in 1972. It stands as a testament to the weird, wonderful flexibility of the English language.
It reminds us that grammar is not just a set of rigid rules to prevent mistakes; it is a complex architecture that can support weight in surprising ways. While we don’t recommend using this sentence in your next email to a colleague, understanding why it works gives you a deeper appreciation for the invisible mechanics happening every time you open your mouth to speak.
So, the next time you feel intimidated by a complex grammar rule, just remember: Don’t let the Buffalo buffalo buffalo you.
