1. Definition of the “Crab Claw” (Cleft Sentence)

The term “crab claw,” while not a formal linguistic term, is used here to represent a cleft sentence. A cleft sentence is a complex sentence that divides a single clause into two clauses, each with its own verb. This grammatical construction is used to emphasize a particular part of the sentence, bringing it into focus for the listener or reader. Cleft sentences are valuable for highlighting specific information, correcting misconceptions, or simply adding emphasis to a particular element.

Cleft sentences are a type of complex sentence because they contain a main clause and a subordinate clause. The main clause typically starts with “it” or a “wh-” word (such as “what,” “who,” “where,” “when,” or “why”), while the subordinate clause provides additional information about the emphasized element. The element being emphasized is known as the focus, and the remaining part of the original sentence is known as the presupposition. Cleft sentences can be classified based on their structure and the type of element they emphasize, as we will explore in more detail in the following sections.

The function of a cleft sentence is primarily to shift the focus of attention. Instead of simply stating a fact, a cleft sentence draws the listener’s or reader’s attention to a specific aspect of that fact.

This can be particularly useful in situations where clarity and emphasis are crucial, such as in arguments, explanations, or narratives. The context in which cleft sentences are used often involves a need to clarify or correct a previous statement or assumption.

They are also commonly used to introduce new information in a way that highlights its importance.

2. Structural Breakdown of Cleft Sentences

Understanding the structure of cleft sentences is essential for using them correctly and effectively. The most common type of cleft sentence, the it-cleft, follows a basic structure: It + be-verb + emphasized element + that-clause. The “be-verb” (is, was, are, were) agrees with the tense of the original sentence. The “that-clause” contains the remaining part of the original sentence, often referred to as the presupposition.

For example, consider the simple sentence: “John ate the apple.” To emphasize that it was *John* who ate the apple, we can create an it-cleft: “It was John that ate the apple.” Here, “John” is the emphasized element, and “that ate the apple” is the presupposition. The structure clearly highlights John as the person who performed the action.

Another type of cleft sentence, the wh-cleft (or pseudo-cleft), uses a “wh-” word to introduce the emphasized element. The structure is: Wh-clause + be-verb + emphasized element. For example, to emphasize what John ate, we can create a wh-cleft: “What John ate was the apple.” In this case, “What John ate” is the wh-clause, and “the apple” is the emphasized element. The be-verb connects the two parts of the sentence. Understanding these structural patterns is key to forming and interpreting cleft sentences correctly.

3. Types of Cleft Sentences

Cleft sentences can be categorized into different types based on their structure and the element they emphasize. The three main types are it-clefts, wh-clefts (pseudo-clefts), and reverse wh-clefts.

Each type serves a slightly different purpose and is constructed in a unique way.

3.1. It-Clefts

It-clefts are the most common type of cleft sentence. They use the structure “It + be-verb + emphasized element + that-clause” to highlight a specific part of the sentence. It-clefts are particularly useful for emphasizing nouns, pronouns, adverbs, or prepositional phrases. The be-verb must agree in number and tense with the original sentence. The “that” can sometimes be replaced with “who” (for people), “which” (for things), or omitted entirely in informal contexts, though this is less common in formal writing.

For example, if the original sentence is “She bought the car yesterday,” an it-cleft can emphasize different elements:
* To emphasize *who* bought the car: “It was she that bought the car yesterday.”
* To emphasize *what* was bought: “It was the car that she bought yesterday.”
* To emphasize *when* it was bought: “It was yesterday that she bought the car.”

3.2. Wh-Clefts (Pseudo-Clefts)

Wh-clefts, also known as pseudo-clefts, use a “wh-” word (what, who, where, when, why, how) to introduce the emphasized element. The structure is “Wh-clause + be-verb + emphasized element.” Wh-clefts are often used to emphasize actions, reasons, or locations. The “wh-” clause functions as the subject of the sentence, and the emphasized element functions as the complement.

For example, if the original sentence is “He went to Paris for vacation,” a wh-cleft can emphasize different elements:
* To emphasize *where* he went: “Where he went was Paris.”
* To emphasize *why* he went: “Why he went to Paris was for vacation.”
* To emphasize *what* he did: “What he did was go to Paris for vacation.”

3.3. Reverse Wh-Clefts

Reverse wh-clefts are less common than it-clefts and wh-clefts, but they are still a valid type of cleft sentence. They invert the structure of a wh-cleft, placing the emphasized element at the beginning of the sentence, followed by the be-verb and the wh-clause. The structure is: Emphasized element + be-verb + wh-clause. Reverse wh-clefts can be used to add a slightly different nuance of emphasis compared to standard wh-clefts.

For example, using the same original sentence “He went to Paris for vacation,” a reverse wh-cleft can emphasize different elements:
*To emphasize *Paris*: “Paris is where he went for vacation.”
*To emphasize *for vacation*: “For vacation is why he went to Paris.”
*To emphasize the entire action: “Going to Paris for vacation is what he did.”

4. Examples of Cleft Sentences

To further illustrate the different types of cleft sentences, let’s examine a variety of examples, categorized by cleft type. These examples will help you understand how to form and use cleft sentences effectively in different contexts.

5. Usage Rules for Cleft Sentences

Using cleft sentences correctly involves adhering to specific grammatical rules. Here’s a breakdown of the key rules to keep in mind:

  1. Agreement: The be-verb in both it-clefts and wh-clefts must agree in number and tense with the original sentence. For example, if the original sentence is in the past tense, the be-verb should also be in the past tense (was or were).
  2. Pronoun Case: Pay attention to the case of pronouns used in cleft sentences. For example, in it-clefts, use the subjective case (I, he, she, we, they) after “it was/is” when referring to the subject of the original sentence.
  3. Relative Pronouns: In it-clefts, use the appropriate relative pronoun (that, who, which) depending on the emphasized element. Use “who” for people and “which” for things. “That” can be used for both but is more common in general contexts.
  4. Word Order: Maintain the correct word order for each type of cleft sentence. It-clefts follow the “It + be-verb + emphasized element + that-clause” structure, while wh-clefts follow the “Wh-clause + be-verb + emphasized element” structure.
  5. Emphasis: Ensure that the emphasized element is clearly highlighted and that the cleft sentence effectively shifts the focus of attention to that element.

Exceptions and Special Cases: While the above rules generally apply, there are some exceptions and special cases to consider. For example, in informal speech, the “that” in it-clefts is often omitted. Additionally, the choice between it-clefts and wh-clefts can sometimes depend on stylistic preferences and the specific nuance you want to convey. Understanding these nuances can help you use cleft sentences more effectively.

6. Common Mistakes with Cleft Sentences

Several common mistakes can occur when using cleft sentences. Being aware of these errors can help you avoid them and use cleft sentences correctly.

Incorrect Verb Agreement: One common mistake is using the wrong form of the be-verb. The be-verb must agree in number and tense with the original sentence.
* Incorrect: It were John who ate the apple.
* Correct: It was John who ate the apple.

Incorrect Pronoun Case: Using the wrong pronoun case is another frequent error. Use the subjective case (I, he, she, we, they) after “it was/is” when referring to the subject.
* Incorrect: It was him that did it.
* Correct: It was he that did it.

Incorrect Word Order: Failing to maintain the correct word order can lead to confusing or ungrammatical sentences.
* Incorrect: What he did the apple eat was.
* Correct: What he ate was the apple.

Unclear Emphasis: If the emphasized element is not clearly highlighted, the cleft sentence may not effectively shift the focus of attention.
* Unclear: It was that he ate the apple. (The emphasis is not clear)
* Clear: It was the apple that he ate. (Clearly emphasizes the apple)

Overuse of Cleft Sentences: While cleft sentences can be effective, overuse can make your writing sound stilted or unnatural. Use them sparingly and only when you specifically want to emphasize a particular element.

8. Advanced Topics in Cleft Sentences

For advanced learners, there are several more complex aspects of cleft sentences to explore. These include the use of cleft sentences in discourse analysis, their role in conveying subtle nuances of meaning, and their application in specific genres of writing.

Cleft Sentences in Discourse Analysis: Cleft sentences play a significant role in how information is structured and presented in a discourse. They can be used to manage the flow of information, introduce new topics, and guide the reader’s attention. Analyzing how cleft sentences are used in different types of texts can provide insights into the author’s intentions and the overall structure of the discourse.

Nuances of Meaning: The choice between it-clefts and wh-clefts can convey subtle differences in meaning. It-clefts are often used to correct a misunderstanding or to provide a specific answer to a question. Wh-clefts, on the other hand, are more often used to introduce new information or to emphasize the reason for something. Understanding these nuances can help you use cleft sentences with greater precision.

Application in Specific Genres: Cleft sentences are particularly useful in argumentative writing, where they can be used to emphasize key points and refute opposing arguments. They are also common in journalistic writing, where they can be used to highlight important facts and draw the reader’s attention to specific details.

9. Frequently Asked Questions (FAQ)

What is the main purpose of using a cleft sentence?

The main purpose of a cleft sentence is to emphasize a specific part of a sentence, bringing it into focus for the listener or reader. It’s a way to highlight particular information or correct a misunderstanding.

Are cleft sentences formal or informal?

Cleft sentences can be used in both formal and informal contexts. However, overuse of cleft sentences can make your writing or speech sound stilted, so it’s best to use them judiciously.

Can I omit the “that” in an it-cleft sentence?

In informal speech, the “that” in an it-cleft sentence is often omitted. However, in formal writing, it’s generally better to include the “that” for clarity and grammatical correctness.

What’s the difference between an it-cleft and a wh-cleft?

It-clefts use the structure “It + be-verb + emphasized element + that-clause” to highlight a specific part of the sentence. Wh-clefts, also known as pseudo-clefts, use a “wh-” word (what, who, where, when, why, how) to introduce the emphasized element.

When should I use a reverse wh-cleft sentence?

Reverse wh-cleft sentences are less common but can be used to add a slightly different nuance of emphasis compared to standard wh-clefts. They place the emphasized element at the beginning of the sentence, followed by the be-verb and the wh-clause.

How can I avoid making mistakes with cleft sentences?

To avoid mistakes, pay attention to verb agreement, pronoun case, word order, and ensure that the emphasized element is clearly highlighted. Also, avoid overuse of cleft sentences.
