Semantic Fields and Castilianization in Galician: A Comparative Study with the Loanword Typology Project

This study examines the correspondence between the borrowability indices from the Loanwoard Typology (LWT) project and Castilianization indices from the Atlas Lingüístico Galego (ALGa) across seven semantic fields. To this end, we identified all Castilianisms in the ALGa and conducted a quantitative analysis to compare these indices. Results obtained indicate a mismatch between the rankings of the LWT project and the ALGa. For example, the field ‘The body’ has the highest level of Castilianization according to the ALGa but the lowest borrowed score in the LWT project. Moreover, Castilianization levels in the ALGa show greater dispersion than borrowability levels from the LWT project. In fact, in each semantic field, many concepts (52.2%) have low levels of Castilianization, between 0% and 10%, and only a few concepts have high levels. A more detailed analysis of three semantic fields (‘The body’, ‘Agriculture and vegetation’, and ‘The physical world’) suggests that explanations based solely on semantic criteria (such as the existence of an unalterable central lexicon) are insufficient; other factors such as prestige, urbanization, cultural modernity, frequency of word usage, and perhaps other intralinguistic factors should be taken into account.
