poster

The word "poster" originates from the verb "to post," which entered English in the 16th century from the French poster, meaning to station or place. This French term derives from the Latin postis, meaning a doorpost or upright, the idea being of affixing a notice to a fixed, public post. By the 19th century, "poster" emerged as an agent noun, first describing a person who posts bills and later the large printed notice itself. In the digital age, its meaning logically extended to a person who posts content on the internet, maintaining the core concept of one who places information into a public space.

Structure: post (to place) + er (agent suffix) - post: From Latin post- (after, behind) via Old French poster (to place, station). In this context, it functions as a verb root meaning "to affix or place in public view." - er: From Old English -ere, an agent noun suffix indicating "a person or thing that performs an action."
