Etymology
the word 'dogmatist' originates from the greek verb dokein, meaning 'to seem' or 'to think', which evolved into dogma, signifying a settled opinion or philosophical decree. in ecclesiastical latin, dogma took on the stronger sense of an authoritative doctrine, often one laid down by a church council. the suffix -istēs, used to form agent nouns, was attached to create a term for a rigid adherent of such doctrines. thus, a dogmatist is etymologically one who inflexibly upholds and asserts beliefs considered as established truths, reflecting the journey from a subjective thought (dokein) to an imposed principle (dogma) and finally to a personification of doctrinal rigidity (dogmatist).
Analysis
Structure: dogmat (doctrine) + ist (person who advocates)
dogmat: from latin dogma, from greek dogma (opinion, belief, decree), from dokein (to seem good, think). functions as the core root meaning a fixed belief or tenet.
ist: from greek -istēs, via latin -ista, a suffix forming agent nouns denoting a person who practices or is concerned with something.
