Lexical Phonology and Sound Change

Introduction to Lexical Phonology and its Relation to Sound Change

Lexical phonology examines the relationship between phonology, morphology, and the processes of sound change. It provides insights into how phonetic and phonological changes impact spoken language over time.

Regular Sound Change Characteristics

Theoretical Perspectives:

  • Neogrammarians: Advocating for phonetically gradual and lexically abrupt changes, Neogrammarians posit that sound changes generally occur uniformly across similar phonemes but are adopted by different lexical items at varying paces.

  • Lexical Diffusionists: They argue for phonetically abrupt and lexically gradual changes, suggesting that while the sounds may change quickly, their integration into the lexicon is a gradual process influenced by social interactions and frequency of usage.

Lexical Diffusion (1960s/1970s):

The 1960s and 1970s marked a stalemate in the sound change debate, as researchers attempted to reconcile differing theories.

  • William Labov: A pivotal figure in sociolinguistics, Labov contextualized sound change in his 1981 work. He emphasized the importance of social factors and existing language variations among speakers, revealing that sound changes are often complex processes influenced by various speakers' linguistic backgrounds and social networks.

  • Conclusion: Both Neogrammarian and lexical diffusionist models have merit but are applicable under different linguistic circumstances, highlighting the need for a flexible approach to understanding sound changes.

Labov's Classification of Sound Changes:

Types of Sound Change:

  • Incorporates both lexical Neogrammarian and diffusion changes.

  • Classification of Features:

    • Discrete/yes or no.

    • Phonetic conditioning: Rough or fine.

    • Lexical exceptions: Yes or no.

    • Grammatical conditioning: Yes or no.

    • Social affect: No or yes.

    • Predictability and learnability criteria are emphasized, helping to distinguish the interplay of sound change mechanisms.

Lexical versus Postlexical Rules:

Delineation between lexical and postlexical rules is critical for understanding how sounds are altered at different linguistic levels. Lexical rules apply within the lexicon, whereas postlexical rules occur at the sentence level.

Failures of Standard Generative Phonology (SGP):

Standard Generative Phonology overlooks key elements of sound change, particularly:

  • Lack of integration of sound change into synchronic (contemporary) grammar.

  • Inadequate treatment of sound changes as similar to phonological rules, ignoring the dynamic and sometimes irregular nature of actual sound shifts.

  • Ignorant of Labov's identification of distinct types of sound change.

Modern Linguistic Theory Recommendations:

There is a recognized need for the integration of synchronic and diachronic analyses to aid in understanding sound change comprehensively. This transition from Standard Generative Phonology to Lexical Phonology effectively incorporates two types of sound change and acknowledges their complexity.

Lexical Phonology Aspects:

Lexical Phonology is characterized by a generative model where each morpheme maintains a single underlying form that produces surface phonetic representations through phonological rules.

  • Characteristics:

    • Less abstraction with similar underlying and surface forms.

    • Fewer phonological rules in place due to the structured nature of phonological processes.

    • Interaction is noted between phonological and morphological rules, emphasizing their interdependent roles.

Research from the Early 1980s:

Research during this period focused on analyzing data concerning suffix addition and how it affected stress shifts in words, contributing to an increased understanding of the phonological structure.

Offered Solution within Lexical Phonology:

Lexical Phonology advocates for the division of phonology into ordered levels or strata, with each stratum having its unique set of phonological and morphological rules that dictate sound behavior in specified environments, allowing for flexibility and variation.

Structure of Lexical Phonology for English Lexicon:

The established levels include:

  • Underived lexical items (basic forms without affixation).

  • Level 1 Morphology and Phonology (basic derivational processes).

  • Level 2 Morphology and Phonology (complex derivational processes involving more intricate transformations).

  • Syntax and Postlexical Phonology (rules governing phonological processes after the syntax has been established).

Distinction between Lexical and Postlexical Rules:

Understanding the distinction is essential as these rules do not function identically. Lexical outputs are characterized as discrete and binary, whereas postlexical outputs are gradient, allowing for more variation and fluidity in pronunciation and meaning.

Comparison of Lexical and Postlexical Rules Against Neogrammarian Changes:

The overlap in the properties of rules changes enhances the understanding of grammatical and phonetic conditioning differences, illustrating the nuances of how each category of changes interacts within the language system.

Conclusion on Overlap and Categorization:

Evidence suggests that lexically diffusing changes correlate closely with lexical phonological rules, while Neogrammarian changes often evolve into postlexical rules, marking a fluid relationship between these categories.

Key Insights into Sound Changes and Their Relationship:

Labov’s observations integrate sound change with phonological rules in Lexical Phonology, emphasizing that understanding the interchangeability of sound change types supports historical linguistics, enhances comprehension of synchrony and diachrony interactions, and offers a more holistic model compared to the SGP.

Dialects of Scots in Practice:

The Scots language showcases a variety of dialects across Scotland, including those from regions such as Orkney and Northern Scots, featuring notable vocabulary differences (e.g., 'turnip' in Scots).

Historical Context of Scots Development:

Scots underwent significant transformations due to influences from Old Northumbrian and changes in English locations following 1603. The adaptation to new English Bible editions contributed to a decline in Scots dialect features, leading to the emergence of Scottish Standard English, which focuses on phonological distinctions.

Notable Phonological Differences Between Scots and Standard British English:

Consonantal variations, such as the distinct [hw] sound, and the rhotic nature of the [r] sound in Scots, distinguish these dialects significantly.

Differences in Vowel Pronunciation:

A thorough summary of vowel sounds in Scots versus Scottish Standard English (SSE) reveals striking contrasts, which illustrate the phonological landscape of the language.

Vowel Length in Scots vs. SSE:

While vowel length is not contrastive in SSE, specific contexts in Scots can result in lengthening, reflecting the complexity of vowel phonology within this dialect.

Framework of the Scottish Vowel Length Rule (SVLR):

SVLR establishes rules governing vowel length concerning surrounding sounds, creating a framework to analyze vowel behavior in Scottish dialects.

Investigating the Prevalence of SVLR in English Varieties:

This investigation focuses on the impact of voicing effects noted in various English varieties and their relationship to the SVLR.

Voicing Effect in RP and General American:

The connection between voiced consonants and vowel duration further illustrates the relationship between phonological elements and their behavioral patterns.

Comparison of Neogrammarian Sound Changes with SVLR:

Vowel length changes display a complex interaction without straightforward categorization, requiring nuanced understanding.

Evolutionary Perspective on SVLR in Scottish Dialects:

A historical review examining SVLR’s development highlights its role in shaping phonological characteristics within Scottish dialects over time, illustrating the impact of social factors and language evolution.

Examination of Long versus Short Vowel Classifications in Speaker Perceptions:

Early steps towards realizing lexical diffusion in vowel pronunciation have been documented, indicating a shift in our understanding of sound change mechanisms.

Linking Neogrammarian Sound Change to the Diffusing Change:

Noting shifts in character and features over time further emphasizes the importance of considering historical context and evolving linguistic patterns.

Contemplation on Additional Theories Regarding Phonological Change:

Exploration into other theories surrounding phonological change is necessary to grasp the totality of language evolution.

Concept of Naturalness:

Naturalness remains a contentious concept within phonological theory, facing definitional challenges.

  • Stampe’s Formalization: Focused on markedness in linguistic features and their evolution, contributing to discussions on how naturalness affects phonetic and phonological structures.

Critiques of Natural Phonology:

Critiques highlight issues surrounding the definition of naturalness, along with its extensions into morphology seen after the 1970s.

Final Remarks and Acknowledgment:

The discussion of Lexical Phonology and sound change emphasizes a multifaceted, nuanced understanding of language evolution, integrating various linguistic theories and practical examples from the Scots dialects and beyond.
