Etymology: Its oldest root is Latin "populus", which the source ties to "people" (or, less likely, "poplar"). From it came the adjective "popularis", which passed through Old French "populaire" into Middle English as "popular". The core meaning stayed close to "of the people" for a long time. The verb "popularise" adds an ending with a longer journey. The "-ise" comes from Ancient Greek "-ίζω", passed into Late Latin as "-izō", then through Middle French "-iser" and Middle English "-isen" before reaching English. English then added "-er", an ending that came via Old English "-ere" and ultimately from Latin "-ārius", to name the person who carries out the action.
