picketer

The word 'picketer' is a modern English agent noun formed from the verb 'picket'. The term 'picket' entered English in the late 17th century from French piquet, originally referring to a pointed stake used as part of a military fence or fortification. This military sense evolved by the 18th century to describe soldiers placed as an outpost or guard. The labor protest sense emerged in the 19th century, drawing a vivid analogy: just as soldiers on picket duty guard a post, striking workers form a line to guard or demonstrate at a workplace entrance. By adding the agent suffix '-er', the word 'picketer' logically denotes the individual person who performs this action of standing in a protest line.
