Sentence correction relative clauses
50 flashcards covering Sentence correction relative clauses for the GMAT Verbal section.
Relative clauses are parts of sentences that add extra information about a noun, typically starting with words like "who," "which," or "that." For example, in the sentence "The book that I read was fascinating," the relative clause "that I read" describes which book is being discussed. These clauses help make writing clearer and more precise, but they can lead to errors if not used correctly, such as when they modify the wrong noun or fail to agree in number or tense.
On the GMAT Verbal section, sentence correction questions often feature relative clauses to test your grammar and logical structure skills. You'll encounter multiple-choice items where you identify and fix errors, like misplaced modifiers or incorrect pronoun usage, such as confusing "that" for essential information with "which" for non-essential details. Common traps include ambiguity in what the clause describes or improper punctuation, so focus on ensuring the clause is placed correctly and enhances the sentence's meaning without altering its intent.
A good tip: Always verify that the relative pronoun clearly links to its intended noun.
Terms (50)
- 01
Relative Clause
A relative clause is a type of dependent clause that provides additional information about a noun or pronoun in the main clause, usually introduced by a relative pronoun such as who, which, or that.
- 02
Restrictive Relative Clause
A restrictive relative clause gives essential information to identify or define the noun it modifies and is not set off by commas, as it is necessary for the sentence's meaning.
- 03
Non-Restrictive Relative Clause
A non-restrictive relative clause provides extra, non-essential information about a noun and is set off by commas, which can be removed without changing the main sentence's meaning.
- 04
Relative Pronoun
A relative pronoun, such as who, whom, which, that, or whose, introduces a relative clause and connects it to the noun or pronoun it modifies in the main clause.
- 05
That in Relative Clauses
In relative clauses, 'that' is used for restrictive clauses to refer to people, animals, or things, and it helps avoid ambiguity by directly linking essential information.
- 06
Which in Relative Clauses
In relative clauses, 'which' is typically used for non-restrictive clauses to refer to things or animals, and it must be preceded by a comma to separate the extra information.
- 07
Who in Relative Clauses
In relative clauses, 'who' is used as a subject pronoun to refer to people, introducing either restrictive or non-restrictive clauses that provide details about the person.
- 08
Whom in Relative Clauses
In relative clauses, 'whom' is used as an object pronoun to refer to people, often in formal contexts, and it must agree with the object role in the clause.
- 09
Where in Relative Clauses
In relative clauses, 'where' introduces a clause that describes a place, typically modifying a noun that represents a location, and it can be restrictive or non-restrictive.
- 10
When in Relative Clauses
In relative clauses, 'when' introduces a clause that describes a time, modifying a noun that refers to a period or event, and it provides specific temporal details.
- 11
Whose in Relative Clauses
In relative clauses, 'whose' is a possessive pronoun that shows ownership or relationship, referring to people or things and linking the clause to the antecedent.
- 12
Comma in Non-Restrictive Clauses
In non-restrictive relative clauses, commas are required to set off the clause from the main sentence, indicating that the information is additional and not essential.
- 13
Antecedent in Relative Clauses
The antecedent in a relative clause is the noun or pronoun that the clause modifies, and the relative pronoun must agree with it in terms of number, gender, and person.
- 14
Subject-Verb Agreement in Relative Clauses
In relative clauses, the verb must agree in number and person with its subject, which is often the relative pronoun acting as the subject of the clause.
- 15
Misplaced Relative Clause
A misplaced relative clause is one that is positioned incorrectly in the sentence, potentially causing ambiguity or changing the intended meaning of the noun it modifies.
- 16
Dangling Relative Clause
A dangling relative clause occurs when the clause does not clearly modify the intended noun, often because the antecedent is missing or unclear, leading to grammatical errors.
- 17
Parallel Structure in Relative Clauses
In relative clauses, elements within the clause must maintain parallel structure, meaning similar items should be phrased consistently to ensure grammatical balance.
- 18
Strategy for Identifying Restrictive Clauses
To identify restrictive clauses, check if the information is essential to the sentence's meaning; if removing it changes the core idea, it is restrictive and should not be set off by commas.
- 19
Common Trap: Using 'Which' for People
A common error is using 'which' to refer to people in relative clauses, whereas 'who' or 'that' should be used instead to maintain correct pronoun agreement.
- 20
Incorrect Comma Usage in Clauses
Placing commas around a restrictive relative clause is a frequent mistake, as it implies the information is non-essential, potentially altering the sentence's intended meaning.
- 21
Example of Correct Restrictive Clause
In the sentence 'The book that I borrowed is on the table,' the restrictive clause 'that I borrowed' correctly identifies which book without needing commas.
This ensures the clause is essential and directly modifies 'book'.
- 22
Example of Incorrect Non-Restrictive Clause
Using a non-restrictive clause without commas, like 'The car which is red needs washing,' is wrong because it should be set off if the color is extra information.
Correct version: 'The car, which is red, needs washing' if red is non-essential.
- 23
Relative Clauses with Prepositions
In relative clauses, prepositions can be used with relative pronouns, such as 'in which' or 'to whom,' to provide more precise relationships between the clause and the antecedent.
- 24
Nested Relative Clauses
Nested relative clauses are clauses within clauses, where one relative clause modifies a noun inside another, requiring careful punctuation to avoid confusion in complex sentences.
- 25
Ambiguous Relative Pronouns
Ambiguous relative pronouns occur when it's unclear which noun the pronoun refers to, leading to confusion; rephrasing is needed for clarity in sentence correction.
- 26
Relative Clauses in Compound Sentences
In compound sentences, relative clauses must be properly integrated without disrupting the coordination between independent clauses, maintaining overall sentence flow.
- 27
Omission of Relative Pronoun
In some restrictive relative clauses, the relative pronoun can be omitted if it is the object of the clause, such as in 'The man I saw was tall,' to create more concise sentences.
- 28
Formal vs. Informal Pronoun Use
In relative clauses, formal writing prefers 'whom' for objects, while informal contexts might use 'who,' but GMAT questions often test the correct formal usage.
- 29
Relative Clauses Modifying Pronouns
Relative clauses can modify pronouns, but this is rare and must ensure agreement, as in 'He who laughs last laughs best,' though it's less common in tested sentences.
- 30
Strategy: Check Pronoun Antecedents
When reviewing relative clauses, always verify that the relative pronoun's antecedent is clear and logical to avoid errors in reference and agreement.
- 31
Common Error: Wrong Verb Tense
In relative clauses, using the wrong verb tense can distort the timeline, so the tense must align with the context of the main clause and the intended meaning.
- 32
Relative Clauses with Quantifiers
Relative clauses can include quantifiers like 'all' or 'some,' and the verb must agree with the quantifier's number, such as 'all of which are correct' for plurals.
- 33
Punctuation in Complex Relative Clauses
In complex sentences with multiple relative clauses, proper punctuation like commas and semicolons is essential to separate clauses and prevent run-on sentences.
- 34
Trap: Overusing Non-Restrictive Clauses
Overusing non-restrictive clauses can make sentences wordy and unclear, so GMAT questions often penalize this by favoring concise, essential information.
- 35
Relative Clauses and Idioms
Some relative clauses involve idiomatic expressions, like 'the reason why,' but GMAT may test for redundancy, as 'reason' and 'why' can sometimes be simplified.
- 36
Advanced: Relative Clauses in Passives
In passive voice constructions, relative clauses must still maintain subject-verb agreement, such as 'The policy that was implemented has succeeded'.
- 37
Strategy for Clause Placement
Place relative clauses immediately after the noun they modify to avoid ambiguity, as moving them can lead to incorrect interpretations in sentence correction.
- 38
Relative Clauses with Adjectives
Relative clauses can function alongside adjectives to modify nouns, but they must not create redundancy, such as avoiding 'the red car that is red'.
- 39
Error: Pronoun Case in Clauses
In relative clauses, the relative pronoun must be in the correct case, like subjective 'who' versus objective 'whom,' to match its role in the clause.
- 40
Example: Correct Use of Where
In the sentence 'This is the city where I was born,' the relative clause 'where I was born' correctly modifies 'city' by specifying its location.
It shows 'where' used for places in a restrictive manner.
- 41
Non-Restrictive Clause Redundancy
Non-restrictive clauses can introduce redundancy if they repeat information already clear from the context, which is a common GMAT trap to watch for.
- 42
Relative Clauses in Lists
When relative clauses modify items in a list, they must apply consistently to each item to maintain parallelism and avoid grammatical inconsistencies.
- 43
Strategy: Eliminate Ambiguity
To correct relative clauses, rephrase if the pronoun creates ambiguity about what it modifies, ensuring the sentence conveys a single clear meaning.
- 44
Relative Clauses and Comparisons
In sentences with comparisons, relative clauses must not disrupt the parallel structure, such as ensuring 'than' clauses match in form.
- 45
Common Trap: Missing Antecedent
A frequent error is a relative clause without a clear antecedent, making the pronoun seem to refer to the wrong noun or nothing at all.
- 46
Advanced: Embedded Questions in Clauses
Relative clauses can include embedded questions, but they must be properly punctuated and integrated to avoid confusing the sentence structure.
- 47
Relative Clauses with Possessives
In relative clauses, possessives like 'whose' must clearly link to the antecedent, ensuring the ownership is unambiguous in the sentence.
- 48
Strategy for Verb Consistency
Ensure that verbs in relative clauses match the tense and mood of the main clause when describing simultaneous or related actions to maintain logical flow.
- 49
Example: Incorrect Whom Usage
In the sentence 'The person whom you think is correct,' 'whom' is used correctly as the object, but errors occur if it's misplaced, like using it as a subject.
Wrong: 'Whom is going?' – should be 'Who is going?'
- 50
Relative Clauses in Definitions
Relative clauses are often used in definitions to specify characteristics, and they must be restrictive to precisely limit the defined term.
