1. Introduction: Navigating the Island Constraints of Comparative Clauses
Comparative clauses, integral parts of sentences expressing comparisons, often present unique syntactic challenges. The question of whether these clauses act as “islands,” restricting the movement of phrases out of them, is a topic of intense debate in linguistic theory. This article aims to comprehensively explore this issue, examining the theoretical underpinnings and empirical evidence surrounding the islandhood of comparative clauses. We will dissect the concept of syntactic islands, investigate the specific properties of comparative clauses that might contribute to their island status, and review the existing literature on extraction from these clauses. By the end of this exploration, you will gain a deeper understanding of the complexities of comparative clause syntax and the implications for theories of grammar. This analysis will draw on various syntactic frameworks and empirical studies to provide a balanced view of the subject. We will also discuss the methodological challenges involved in studying island effects and the types of experimental designs used to investigate these phenomena.
2. Defining Syntactic Islands: A Theoretical Overview
The concept of “syntactic islands” was introduced by John Robert Ross in his groundbreaking dissertation, “Constraints on Variables in Syntax” (1967). Ross observed that certain syntactic environments block the movement of constituents, preventing operations such as wh-movement or topicalization from extracting elements from within them. These environments are thus referred to as “islands” because they act as barriers to syntactic operations.
2.1. Types of Syntactic Islands
Several types of syntactic islands have been identified in the linguistic literature, each characterized by specific structural properties:
-
Wh-islands: These islands are created by clauses introduced by wh-words (e.g., who, what, where, why). Extracting an element from within a wh-island typically results in ungrammaticality, as illustrated in the following example:
- *What did John wonder who saw? (Extraction from a wh-island)
-
Sentential Subject Islands: Sentential subjects, which are clauses functioning as the subject of a sentence, also act as islands. Extraction from these subjects is generally prohibited:
- *Who is [that John likes] obvious to? (Extraction from a sentential subject)
-
Complex Noun Phrase Islands: These islands involve extraction from within a noun phrase that contains a relative clause or a sentential complement.
- *Which book did Mary read [the review of that]? (Extraction from a relative clause within a noun phrase)
-
Coordinate Structure Islands: Coordinate structures, formed by conjoining two or more constituents with a coordinator like and or or, also resist extraction.
- *What did John buy apples and? (Extraction from a coordinate structure)
2.2. Theoretical Explanations for Island Constraints
Various theoretical accounts have been proposed to explain the existence of island constraints. Some prominent explanations include:
-
Subjacency: This principle, proposed by Noam Chomsky, restricts the distance that a constituent can move in a single step of a syntactic derivation. Subjacency states that a movement operation cannot cross more than one “bounding node,” which typically includes S (sentence) and NP (noun phrase).
-
Empty Category Principle (ECP): The ECP requires that every non-lexical empty category (such as a trace left by movement) be properly governed. Island constraints can be seen as violations of the ECP, where the trace left by extraction is not properly governed.
-
Minimal Link Condition (MLC): The MLC, a principle within Minimalist Syntax, requires that movement operations target the closest possible landing site. Extracting an element from an island might violate the MLC if a closer landing site is available.
-
Processing-Based Accounts: These accounts suggest that island effects arise from the cognitive difficulty of processing sentences that involve long-distance dependencies created by extraction.
3. Comparative Clauses: Structure and Function
Comparative clauses are subordinate clauses that express a comparison between two entities or situations. They typically involve the use of comparative markers such as than or as. Understanding the structure and function of comparative clauses is essential for evaluating their potential island status.
3.1. Types of Comparative Clauses
Comparative clauses can be classified into several types based on their syntactic structure and the type of comparison they express:
-
Comparative Clauses of Inequality: These clauses express a difference in degree or amount between two entities. They typically involve the use of than.
- John is taller than Mary is.
- This book is more interesting than that one is.
-
Comparative Clauses of Equality: These clauses express a similarity in degree or amount between two entities. They typically involve the use of as.
- John is as tall as Mary is.
- This book is as interesting as that one is.
-
Correlative Comparative Clauses: These clauses express a proportional relationship between two entities, often involving the structure “the more…, the more…”.
- The more you study, the more you learn.
- The harder you work, the more successful you become.
3.2. Syntactic Structure of Comparative Clauses
The syntactic structure of comparative clauses can be complex and has been the subject of much linguistic analysis. A common analysis involves the presence of an operator (such as than or as) that binds a variable within the comparative clause. This variable represents the element being compared.
For example, in the sentence “John is taller than Mary is,” the comparative clause “than Mary is” involves a comparison of height. The operator than binds a variable representing Mary’s height, indicating that John’s height exceeds Mary’s.
3.3. Theoretical Challenges in Analyzing Comparative Clauses
Analyzing comparative clauses poses several theoretical challenges, including:
-
Ellipsis: Comparative clauses often involve ellipsis, where certain elements are omitted because they are understood from the context. For example, in the sentence “John is taller than Mary,” the verb is is elided in the comparative clause.
-
Movement: Some analyses of comparative clauses involve movement operations, where elements are moved from their base position to a higher position in the structure. For example, the comparative marker than might be analyzed as moving to the front of the clause.
-
Interpretation: Determining the precise meaning of comparative clauses can be challenging, especially when dealing with complex comparisons or comparisons involving multiple variables.
4. The Islandhood of Comparative Clauses: Evidence and Arguments
The central question of this article is whether comparative clauses act as islands, restricting extraction from within them. The evidence and arguments surrounding this issue are mixed, with some studies suggesting that comparative clauses are indeed islands, while others find evidence of permissible extraction under certain conditions.
4.1. Arguments for Islandhood
Several arguments support the idea that comparative clauses are islands:
-
Structural Complexity: Comparative clauses often involve complex syntactic structures, including ellipsis and movement operations. This complexity might make it difficult to extract elements from within them.
-
Operator-Variable Binding: The presence of an operator that binds a variable within the comparative clause might create a barrier to extraction. The operator might block the movement of other elements out of the clause.
-
Empirical Evidence: Some studies have found that extraction from comparative clauses results in ungrammaticality, suggesting that these clauses are islands.
4.2. Arguments Against Islandhood
Conversely, several arguments challenge the idea that comparative clauses are always islands:
-
Variability: The acceptability of extraction from comparative clauses can vary depending on the specific type of comparative clause, the nature of the extracted element, and the surrounding syntactic context.
-
Processing Factors: Island effects might be influenced by processing factors rather than strict grammatical constraints. It is possible that extraction from comparative clauses is dispreferred due to the cognitive difficulty of processing the resulting sentences.
-
Empirical Evidence: Some studies have found that extraction from comparative clauses is acceptable under certain conditions, suggesting that these clauses are not always islands.
4.3. Specific Cases of Extraction from Comparative Clauses
To further explore the islandhood of comparative clauses, it is helpful to examine specific cases of extraction and assess their acceptability:
-
Extraction of a Subject: Extracting the subject of a comparative clause is often considered to be more acceptable than extracting other elements.
- Who is John taller than? (Extraction of the subject)
-
Extraction of an Object: Extracting the object of a comparative clause is generally considered to be less acceptable.
- *What is John taller than Mary bought? (Extraction of the object)
-
Extraction from a Comparative Clause of Equality: Extraction from comparative clauses of equality (using as) might be more acceptable than extraction from comparative clauses of inequality (using than).
- Who is John as tall as? (Extraction from a comparative clause of equality)
5. Empirical Studies on Extraction from Comparative Clauses
Several empirical studies have investigated the islandhood of comparative clauses using various methodologies, including acceptability judgment tasks, corpus analyses, and experimental techniques. These studies have yielded mixed results, highlighting the complexities of the issue.
5.1. Acceptability Judgment Tasks
Acceptability judgment tasks involve presenting participants with sentences that vary in their grammatical acceptability and asking them to rate the sentences on a scale. These tasks can be used to assess the effects of extraction from comparative clauses on grammaticality.
For example, a study might compare the acceptability of sentences with extraction from a comparative clause to sentences without extraction or with extraction from a non-island environment. The results can reveal whether extraction from comparative clauses leads to a significant decrease in acceptability, indicating an island effect.
5.2. Corpus Analyses
Corpus analyses involve examining large collections of naturally occurring text to identify instances of extraction from comparative clauses. By analyzing the frequency and distribution of these instances, researchers can gain insights into the acceptability and usage patterns of extraction.
However, corpus analyses have limitations, as the absence of a particular construction in a corpus does not necessarily mean that it is ungrammatical. It is possible that the construction is simply rare or dispreferred for stylistic reasons.
5.3. Experimental Techniques
Experimental techniques, such as eye-tracking and self-paced reading, can be used to investigate the cognitive processes involved in processing sentences with extraction from comparative clauses. These techniques can provide insights into the real-time processing difficulties associated with island violations.
For example, an eye-tracking study might measure the amount of time participants spend reading different parts of a sentence with extraction from a comparative clause. Increased reading times in the region of the extraction site or the landing site could indicate processing difficulties associated with the island violation.
6. Theoretical Accounts of Extraction from Comparative Clauses
Several theoretical accounts have been proposed to explain the patterns of acceptability and ungrammaticality observed in extraction from comparative clauses. These accounts vary in their assumptions about the nature of island constraints and the syntactic structure of comparative clauses.
6.1. Subjacency-Based Accounts
Subjacency-based accounts argue that extraction from comparative clauses is constrained by the principle of subjacency. According to these accounts, extraction crosses too many bounding nodes (S or NP), resulting in a violation of subjacency and ungrammaticality.
However, subjacency-based accounts face challenges in explaining the variability observed in extraction from comparative clauses. Some instances of extraction appear to be more acceptable than others, even though they all involve crossing the same number of bounding nodes.
6.2. ECP-Based Accounts
ECP-based accounts argue that extraction from comparative clauses violates the Empty Category Principle. According to these accounts, the trace left by extraction is not properly governed, resulting in ungrammaticality.
However, ECP-based accounts also face challenges in explaining the variability observed in extraction from comparative clauses. The conditions under which a trace is properly governed can be complex and might depend on factors that are not directly related to the structure of the comparative clause.
6.3. Minimalist Accounts
Minimalist accounts attempt to explain island constraints in terms of fundamental principles of grammar, such as the Minimal Link Condition. According to these accounts, extraction from comparative clauses violates the MLC because it involves moving an element over a closer potential landing site.
Minimalist accounts offer a more principled explanation of island constraints, but they also require careful analysis of the syntactic structure and movement operations involved in extraction.
6.4. Processing-Based Accounts
Processing-based accounts argue that island effects arise from the cognitive difficulty of processing sentences with long-distance dependencies created by extraction. According to these accounts, extraction from comparative clauses is dispreferred because it places a heavy burden on working memory and other cognitive resources.
Processing-based accounts can explain the variability observed in extraction from comparative clauses by appealing to factors such as the length of the extraction path, the complexity of the intervening material, and the availability of contextual cues.
7. Cross-Linguistic Perspectives on Comparative Clause Islands
The islandhood of comparative clauses is not uniform across languages. Some languages exhibit stricter island constraints than others, while some languages allow extraction from comparative clauses more freely. Examining cross-linguistic variation can provide valuable insights into the nature of island constraints and the factors that influence their strength.
7.1. Languages with Strict Island Constraints
Some languages, such as English, generally exhibit strict island constraints on extraction from comparative clauses. Extraction from these clauses typically results in ungrammaticality, suggesting that they are strong islands.
However, even in languages with strict island constraints, there can be variability in the acceptability of extraction depending on the specific type of comparative clause and the nature of the extracted element.
7.2. Languages with Permissive Island Constraints
Other languages, such as Scandinavian languages (e.g., Swedish, Norwegian, Danish), allow extraction from comparative clauses more freely. Extraction from these clauses is often acceptable, suggesting that they are weak islands or not islands at all.
The permissiveness of Scandinavian languages with respect to extraction from comparative clauses has been attributed to various factors, including the syntactic structure of comparative clauses in these languages and the presence of grammatical features that facilitate long-distance dependencies.
7.3. Factors Influencing Cross-Linguistic Variation
Several factors might contribute to the cross-linguistic variation observed in the islandhood of comparative clauses:
-
Syntactic Structure: The syntactic structure of comparative clauses can vary across languages, affecting the ease with which elements can be extracted from them.
-
Grammatical Features: The presence of grammatical features such as case marking, agreement, and resumptive pronouns can influence the acceptability of extraction.
-
Processing Factors: Processing factors might also play a role, as the cognitive difficulty of processing sentences with extraction can vary depending on the language and the specific construction.
8. Implications for Theories of Grammar
The islandhood of comparative clauses has significant implications for theories of grammar. The patterns of acceptability and ungrammaticality observed in extraction from these clauses can provide valuable evidence for evaluating different theoretical accounts of island constraints and syntactic structure.
8.1. Testing Theoretical Predictions
The study of comparative clause islands can be used to test the predictions of different theoretical frameworks, such as Subjacency Theory, the Empty Category Principle, and Minimalist Syntax. By comparing the predictions of these theories with the empirical data, researchers can gain insights into the strengths and weaknesses of each framework.
8.2. Refining Syntactic Analyses
The analysis of comparative clause islands can also lead to refinements in our understanding of the syntactic structure of comparative clauses. By examining the conditions under which extraction is permissible or prohibited, researchers can develop more accurate and detailed models of the syntactic operations involved in comparative clause formation.
8.3. Understanding the Nature of Island Constraints
The study of comparative clause islands can contribute to a deeper understanding of the nature of island constraints. By exploring the factors that influence the strength of island effects, researchers can gain insights into the cognitive and grammatical mechanisms that underlie these constraints.
9. Methodological Considerations in Studying Island Effects
Studying island effects presents several methodological challenges. Researchers must carefully design their experiments and analyses to ensure that they are accurately measuring the effects of island constraints and not confounding them with other factors.
9.1. Controlling for Confounding Variables
It is essential to control for confounding variables that might influence the acceptability of sentences with extraction. These variables can include the length of the sentence, the complexity of the syntactic structure, and the frequency of the words used in the sentence.
9.2. Using Appropriate Statistical Analyses
Researchers should use appropriate statistical analyses to analyze the data collected in their experiments. These analyses should take into account the variability in participants’ judgments and the potential for random error.
9.3. Considering Processing Factors
It is important to consider processing factors that might influence the acceptability of sentences with extraction. These factors can include the working memory capacity of participants and the availability of contextual cues.
9.4. Ensuring Ecological Validity
Researchers should strive to ensure that their experiments have ecological validity, meaning that they resemble real-world language use as closely as possible. This can involve using naturalistic stimuli and collecting data in ecologically valid settings.
10. Future Directions in Research on Comparative Clause Islands
The study of comparative clause islands is an ongoing area of research, with many questions still unanswered. Future research should focus on addressing these questions and developing more comprehensive theories of island constraints.
10.1. Investigating Cross-Linguistic Variation

10.2. Exploring Processing Factors
Future research should explore the role of processing factors in island effects. By using experimental techniques such as eye-tracking and self-paced reading, researchers can gain insights into the cognitive processes involved in processing sentences with extraction from comparative clauses.
10.3. Developing Computational Models
Future research should focus on developing computational models of island constraints. These models can be used to simulate the effects of extraction on grammaticality and to test the predictions of different theoretical accounts.
10.4. Examining the Interaction with Other Syntactic Phenomena
Future research should examine the interaction between comparative clause islands and other syntactic phenomena, such as ellipsis, movement, and agreement. By exploring these interactions, researchers can gain a more comprehensive understanding of the complexities of comparative clause syntax.
