Peter Trudgill: Languages in Contact and Isolation: Mature Phenomena and Societies of Intimates

Introduction to Sociolinguistic Typology00:02:55

Professor Trudgill introduces sociolinguistic typology, seeking to determine the connection between social factors—such as language contact, social network density, and community size—and the structural features of human languages.

The Duality of Language Contact00:07:05

Trudgill explains that language contact can lead to both simplification (common in short-term adult-to-adult contact) and complexification (additive borrowing in long-term co-territorial contact involving children).

Mature Phenomena and Societies of Intimates00:17:16

Defining 'mature phenomena' as features requiring long periods of historical development, Trudgill hypothesizes that these complex features are most likely to develop in small, stable, isolated 'societies of intimates' and are highly vulnerable in large, mobile 'societies of strangers'.

Chronological Bias in Linguistic Sampling00:26:03

The speaker addresses the challenge of chronological bias in typology, noting that modern standard languages are atypical of human history, as the vast majority of human language development occurred in pre-urban, Neolithic 'societies of intimates'.

Evidence for Endangered Features00:32:07

Trudgill provides specific examples of 'cross-linguistically dispensable' categories—such as dual number, complex pronominal systems, and evidentiality—arguing these are uniquely suited to intimate social settings and are currently disappearing as those societies vanish.

Conclusion: The Future of Linguistic Complexity00:54:40

Concluding that major modern languages (often products of high contact/creolization) lack these mature phenomena, Trudgill warns that as societies of strangers continue to expand, many of the world's most complex and unique linguistic features face extinction.
