The word évidemment is derived from the French word évident, which comes from the Latin word evidentem. Evidentem is the accusative form of evidens, which is a combination of the prefix e- (meaning out or out of) and the verb videre (meaning to see). Therefore, the literal meaning of évident or évidemment can be understood as out of sight or visible. Over time, évident in French has evolved to mean obvious or clear, and évidemment is an adverbial form of évident, meaning obviously or clearly.
