Abstract

Cladistic hypotheses are ideally based on arguments that use cumulative evidence from a wide range of shared innovations inherited from a more recent ancestor. The majority of historical linguists would agree that the best evidence for subgrouping would be shared phonological and morphological innovations, while evidence from proportions of shared lexical cognacy is less reliable for linguistic subgrouping. Recent high-profile studies have appeared, however, that have been based exclusively on comparative lexical material. The results of these methods have been sharply criticised, but in spite of the criticisms to cognacy-based approaches, there remains some potential that the lexical cognacy may provide some useful data to supplement cladistic hypotheses as part of an overall assessment of the complete bundle of available isoglosses. If lexical cognacy judgements can be treated as a potential source of data for cladistic hypotheses, how can they be implemented in a methodologically rigorous way? This chapter focuses on case studies from methodological issues that have arisen in encoding Indo-European lexical cognacy data on the Indo-European Cognate Relationships ( IE-CoR) database project based at the Max Planck Institute for the Science of Human History. These issues are illustrated through case studies from problems that have arisen in assigning cognacy coding to lexical data. As such this chapter contributes a discussion towards improving the reliability of cognacy data for cladistic analyses as a supplement to more traditional analyses based on comparative phonological and morphological criteria.

A Study in Historical Dialectology and Linguistic Classification
The Aeolic dialects of Ancient Greek (Lesbian, Thessalian, and Boeotian) are characterised by a small bundle of commonly shared innovations, yet at the same time they exhibit remarkable linguistic diversity. While traditionally classified together in modern scholarship since the nineteenth century, in recent decades doubt has been cast on whether they form a coherent dialectal subgroup of Ancient Greek. In this monograph Matthew Scarborough outlines the history of problem of Aeolic classification from antiquity to the present day, collects and analyses the primary evidence for the linguistic innovations that unite and divide the group, and contributes an innovative new statistical methodology for evaluating highly contested genetic subgroupings in dialectology, ultimately arguing in support of the traditional classification.
