Buffalo buffalo Buffalo buffalo buffalo buffalo Buffalo buffalo
"Buffalo buffalo Buffalo buffalo buffalo buffalo Buffalo buffalo" is a grammatically valid sentence in American English, used as an example of how homonyms and homophones can be used to create complicated linguistic constructs. It has been discussed in literature since 1972 when the sentence was used by William J. Rapaport, an associate professor at the University at Buffalo. It was posted to Linguist List by Rapaport in 1992. It was also featured in Steven Pinker's 1994 book The Language Instinct as an example of a sentence that is "seemingly nonsensical" but grammatical. Pinker names his student Annie Senghas as the inventor of the sentence.
The sentence's meaning becomes clearer when it's understood that it uses the city of Buffalo, New York and the somewhat-uncommon verb "to buffalo" (meaning "to bully or intimidate"), and when the punctuation and grammar is expanded so that the sentence reads as follows: "Buffalo buffalo that Buffalo buffalo buffalo, buffalo Buffalo buffalo." The meaning becomes even clearer when synonyms are used: "Buffalo bison that other Buffalo bison bully, themselves bully Buffalo bison."
Sentence construction 
The sentence is unpunctuated and uses three different readings of the word "buffalo". In order of their first use, these are
- a. the city of Buffalo, New York, United States, which is used as a noun adjunct in the sentence and is followed by the animal;
- n. the noun buffalo, an animal, in the plural (equivalent to "buffaloes" or "buffalos"), in order to avoid articles;
- v. the verb "buffalo" meaning to bully, confuse, deceive, or intimidate.
Marking each "buffalo" with its use as shown above gives:
- Buffaloa buffalon Buffaloa buffalon buffalov buffalov Buffaloa buffalon.
The sentence makes use of the allowability in English of reduced relative clauses – those that contain no relative pronoun or other relativizing marker. Hence the relative that or which that might appear between the second and third words of the sentence can be omitted.
Thus, the sentence when parsed reads as a claim that bison who are intimidated or bullied by bison are themselves intimidating or bullying bison (at least in the city of Buffalo– implicitly, Buffalo, NY):
- Buffalo buffalo (buffalo from Buffalo NY) [that] Buffalo buffalo buffalo (that the buffalo from Buffalo NY bully) buffalo Buffalo buffalo (are bullying buffalo from Buffalo NY)
- [Those] buffalo(es) from Buffalo [that are intimidated by] buffalo(es) from Buffalo intimidate buffalo(es) from Buffalo.
- Bison from Buffalo, New York, who are intimidated by other bison in their community, also happen to intimidate other bison in their community.
- The buffalo from Buffalo who are buffaloed by buffalo from Buffalo, buffalo (verb) other buffalo from Buffalo.
- Buffalo buffalo (main clause subject) [which the] Buffalo buffalo (subordinate clause subject) buffalo (subordinate clause verb) buffalo (main clause verb) Buffalo buffalo (main clause direct object).
The sentence can be clarified by substituting the synonym "bison" for the animal "buffalo", "bully" for the verb "buffalo", and "New York" to refer to the state of the city Buffalo:
- "New York bison New York bison bully bully New York bison", or:
- "New York bison whom other New York bison bully, themselves bully New York bison".
Or, alternatively with the city name intact:
- "Buffalo bison Buffalo bison bully bully Buffalo bison".
Removing the classifier noun "Buffalo" (the city) further clarifies the sentence (note that the initial capital is retained as the common noun "buffalo" now starts the sentence):
- "Buffalo buffalo buffalo buffalo buffalo."
- "Bison [that other] bison bully [also] bully bison."
Thomas Tymoczko has pointed out that there is nothing special about eight "buffalos"; any sentence consisting solely of the word "buffalo" repeated any number of times is grammatically correct. The shortest is "Buffalo!", which can be taken as an imperative instruction to bully someone ("[You] buffalo!") with the implied subject "you" removed. Tymoczko uses the sentence as an example illustrating rewrite rules in linguistics.
Other words using the same pattern 
Other English words can be used to make grammatical (but not necessarily meaningful) sentences of this form, containing endless consecutive repetitions. Any word that is both a plural noun and an uninflected transitive verb will work; for example, police or dice.
A somewhat similar non-punctuated example is "James while John had had had had had had had had had had had a better effect on the teacher". This could concern a situation in an English class regarding the usage of the word had, and might be punctuated as, "James, while John had had 'had', had had 'had had'; 'had had' had had a better effect on the teacher."
