Sentence Check

" Buffalo buffalo Buffalo buffalo buffalo buffalo Buffalo buffalo. " is a grammatically correct sentence used as an example of how homonyms and homophones can be used to create complicated 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 .

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 (or any other place named "Buffalo"), which is used as an adjective 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

Thus, the sentence when parsed reads as a description of the pecking order in the social hierarchy of buffaloes living in Buffalo:

"Buffalo buffalo (main clause Subject) Buffalo buffalo (subordinate clause Direct Object) buffalo buffalo Buffalo buffalo ."

It may be revealing to read the sentence replacing all instances of the animal buffalo with "people" and the verb buffalo with "intimidate". The sentence then reads

Preserving the meaning more closely, substituting the synonym "bison" for "buffalo" (animal), "bully" for "buffalo" (verb) and leaving "Buffalo" to mean the city, yields

To further understand the structure of the sentence, one can replace "Buffalo buffalo" with any number of noun phrases. Rather than referring to "Buffalo buffalo" intimidating other "Buffalo buffalo", one can use noun phrases like "Alley cats", "Junkyard dogs", and "Sewer rats". The sentence then reads

This has the same sentence structure as 'Buffalo buffalo Buffalo buffalo buffalo buffalo Buffalo buffalo'.

Ambiguity

If the capitalization is ignored, the sentence can be read another way:

That is, bison from Buffalo intimidate (other) bison from Buffalo that bison from Buffalo intimidate.

Parsing difficulty

Other than the confusion caused by the homophones, the sentence is difficult to parse for several reasons:

1. The use of "buffalo" as a verb is not particularly common and itself has several meanings.
2. The construction in the plural makes the verb "buffalo", like the city, rather than "buffaloes".
3. The choice of "buffalo" rather than "buffaloes" as the plural form of the noun makes it identical to the verb.
4. There are no grammatical cues from syntactically significant words such as articles (again possible because of the plural construction) or the relative pronoun "that".
5. The absence of punctuation makes it difficult to read the flow of the sentence.
6. Consequently, it is a garden path sentence, i.e., it cannot be parsed by reading one word at a time without backtracking.
7. The statement includes a universal predicate about a class and also introduces a later class (the buffalo that are intimidated by intimidated buffalo) that may, but need not, be distinct from the first class.
8. Parsing is ambiguous if capitalization is ignored. Using another adjectival sense of 'buffalo' ('cunning', derived from the sense 'to confuse'), the following alternative parsing is obtained: 'Buffalo bison bison bully, bully cunning Buffalo bison' (that is, the head of the verb phrase occurs one 'buffalo' earlier).
9. The relative clause is center embedded, a construction which is hard to parse.

Extension

There is nothing special about eight "buffalo"s; indeed, a sentence with "buffalo" repeated any number of times is grammatically correct (according to Chomskyan theories of grammar). The shortest is 'Buffalo!', meaning either 'Bully (someone)!', or 'Look, there are buffalo here!', or 'Behold, it is the city of Buffalo!'.

Other words

Other English words can be used to make grammatical sentences of this form, containing many consecutive repetitions. Any word that is both an animate plural noun and a transitive verb will work. One un-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."

Other words which can be used in this manner include police , fish , people , and smelt .
