Obviousness → It is formed from "ob-" (meaning over or against) and "via" (meaning way) combined with the suffix "-ness" (indicating a state or quality). The word "obviousness" refers to the quality of being easily seen or understood, as if something is clearly in the way or apparent.
Think of something that is 'over' or 'against' the usual way of understanding — that's why obviousness means the quality of being clear and easily understood.
