Claims about lexical elaboration (e.g. Mongolian has many horse-related terms) are widespread in the scholarly and popular literature. Here we show that computational analyses of bilingual dictionaries can be used to test claims about lexical elaboration at scale. We validate our approach by introducing BILA, a data set including 1574 bilingual dictionaries, and showing that it confirms 147 out of 163 previous claims from the literature. We then identify previously unreported examples of lexical elaboration, and analyze how lexical elaboration is influenced by ecological and cultural variables. Claims about lexical elaboration are sometimes dismissed as either obvious or fanciful, but our work suggests that large-scale computational approaches to the topic can produce non-obvious and well-grounded insights about language and culture.
