purist

the word 'purist' is a relatively modern english formation, entering the language in the early 18th century. it is constructed from the adjective 'pure', which itself descends from the latin 'purus', a term of ancient indo-european lineage signifying physical and moral cleanliness. the suffix '-ist', of greek origin via latin, is a common english agentive suffix denoting an adherent of a practice or doctrine. therefore, a 'purist' is literally 'one who adheres to purity'—originally in language, referring to opposition to foreign loanwords, and later extending to any strict adherence to traditional principles in an art, craft, or ideology, emphasizing an uncompromising desire to maintain an unmixed, uncorrupted standard.

Structure: pur (pure) + ist (one who practices) - pur: from latin 'purus' meaning clean, clear, unmixed. functions as the core root conveying the concept of purity. - ist: from greek '-istes', via latin '-ista', a suffix forming agent nouns meaning 'one who practices or is concerned with something'.
