Usage: Use "comparison" to describe the action of noting similarities and differences between two or more things. It refers to the entire process of evaluating how items relate to one another rather than a single point of contrast.
The word entered English from the Old French comparaison, which derived from the Latin comparātiō. Originally meaning a bringing together or placing side by side, it retained this sense when adopted into Middle English as comparisoun.
