Etymology
'bayesian' originates from English, specifically from the surname 'Bayes' (Thomas Bayes) combined with the adjectival suffix '-ian' meaning 'related to' or 'belonging to'.
'bayesian' developed as an adjective and noun in English in the 19th and 20th centuries to describe ideas, methods, and people associated with Thomas Bayes' theorem and subsequent Bayesian probability theory.
Initially, it referred narrowly to things directly connected to Thomas Bayes or his theorem; over time it broadened to denote the larger statistical/philosophical approach of Bayesian probability and its practitioners.
