Syntax with Sherlock - Sentence Ambiguity Illustrated and Diagrammed

*For simplicity's sake, because the phrase "using binoculars" functions like a prepositional phrase, I have taken the liberty of changing "using" to "with" for the diagrams.

Here is a syntactic diagram of the version of the sentence pictured on the left.

Here is a syntactic diagram of the version of the sentence pictured on the right.




The above syntactic trees show that the ambiguous nature of the sentence results from the possibility of the prepositional phrase attaching to the noun phrase or directly to the verb phrase.

An Introduction to Sentence Types and Basic Sentence Trees

Simple Sentence

Every sentence must contain a noun phrase and a verb phrase (in some sentences the noun phrase may be null).

Coordinate Sentence

Every coordinate sentence must contain at least two simple sentences joined by a coordinating conjunction.

Complex Sentence

Every complex sentence must contain one simple sentence and at least one dependant clause that includes a subordinating conjunction and a simple sentence.

Complex-Coordinate Sentence (example 1)

Complex-Coordinate Sentence (example 2)

Every complex-coordinate sentence must contain at least two simple sentences joined by a coordinating conjunction and at least one dependant clause that includes a subordinating conjunction and a sentence.


Please note: Because of the recursive nature of language a coordinate sentence could have an unlimited number of simple sentences joined by coordinating conjunctions, and a complex sentence could have an unlimited number of dependant clauses joined by subordinating conjunctions, and a complex-coordinate sentence could have an unlimited number of simple sentences joined by coordinating conjunctions and dependant clauses joined by subordinating conjunctions, and, and, and, and.....

Blossoms Crash on Garden Path Resulting in Conflicting Trees

Garden path sentences are those that lead a reader down a path to an incorrect semantic and/or syntactic interpretation of the sentence during the initial analysis or parsing of the sentence. The field of psycholinguistics has shown that these incorrect interpretations occur because readers process sentences one word at a time.



A simple yet cogent example of a garden path sentence is:

The old man the boat.

When reading this sentence the most likely initial interpretation (illustrated by the syntactic tree below) is that "old" is an adjective describing "man". But what happens when you get to "the boat"? This can't be a sentence without a verb.
By backtracking and reading the sentence again the proper interpretation with "old" being a collective noun and "man" being a verb can be reached. In other words, "the boat is manned by the old (people)."
Similar to garden path sentences are newspaper headlines that are written in such a way as to lead a reader to an incorrect interpretation (often by omission of words). These headlines have been dubbed "crash blossoms" based on the following headline:





Here is a diagram of the likely initial interpretation followed by a diagram of the intended interpretation (with words added for clarification).

And here are two additional crash blossoms that I find particularly amusing followed by their respective conflicting syntactic trees.

What better way to have fun with an intentionally ambiguous cartoon than to diagram the ambiguous sentence in the cartoon!

Gotta love the humor that ambiguity provides.

Diagramming Sentences: The Syntactic Tree

The method of sentence diagramming(shown below) that most high school students still learn today is based on on the work of Alonzo Reed and Brainerd Kellogg from 1877.

The sentence diagrams preferred by linguists today are based on the work of Noam Chomsky and Ray Jackendoff and are called syntactic trees. Syntactic trees are preferred because they illustrate the dimensionality of sentences; in other words they show that sentences are more than just strings of words with a flat structure.

All people should be as happy as linguists.
