Lexico-semantic stability in the anatomical domain in the Mayan language family

This paper deals with lexico-semantic stability, specifically in the anatomical domain. The main goal is to develop a method for measuring semantic polysemy and shift, in order to address: (1) the validity of standardized vocabulary lists (e.g., Swadesh 1950, 1952, 1955; Holman et al. 2008; Haspelmath & Tadmor 2009a, 2009b) for investigating cross-linguistic stability; and (2) the difference between basic and stable vocabulary (Ratliff 2006; Matisoff 2009), and its implications for studying remote relationships between language families, on the one hand, and subgroup differentiation within language families, on the other. To study these problems, a total of 50 etyma from the anatomical domain were selected from the Preliminary Etymological Mayan Database (Kaufman with Justeson 2003), and these were then classified employing the novel metric, and further analyzed by means of statistical methods. The results point to: (1) no specific correlation with the stability rankings of the Swadesh and Leipzig-Jakarta lists; (2) support for the "basicness" of etyma from the anatomical domain; (3) several significant relationships between stability and polysemy scores and independent variables relevant to the anatomical domain; (4) evidence of lexico-semantic stability score affinities between Mayan subgroups; and (5) evidence supporting the utility of polysemies to investigate subgrouping and language contact. The paper also offers conclusions and areas for further research.
