The word 'universalist' is built upon the core concept of 'the whole', derived from the Latin 'universus', itself a combination of 'unus' (one) and 'versus' (turned). The suffix '-al' transforms this into the adjective 'universal', meaning 'pertaining to all'. Finally, the agent suffix '-ist' is appended, creating a noun for a person who advocates or believes in a doctrine encompassing all. Thus, the term's logic moves from the literal idea of 'turned into one' to the abstract principles of inclusivity, whether in theological salvation or encyclopedic knowledge.

Structure: univers (whole) + al (adjective suffix) + ist (agent suffix) - univers: From Latin 'universus', meaning 'whole, entire, all together'. - al: A suffix forming adjectives, from Latin '-alis'. - ist: A suffix forming agent nouns, from Greek '-istes', via Latin '-ista'.
