One who plays checkers or someone who marks things in a checkered pattern (archaic term).
From 'chicque' (related to checkerboard patterns) with the agent suffix '-er,' creating a noun for one who engages in the action. This is largely historical.
This word represents a pattern in English where we create '-er' nouns for almost any verb, even temporary or rare ones—'chicquer' is obsolete, but the suffix '-er' remains one of our most productive word-building tools.
