unintentionEtymologyBack-formation from unintentional. By surface analysis, un- + intention.nounSomething that is unintentional.“The frameup is an unconscious (occasionally semiconscious) mechanism. An unconscious mechanism is a kink in the mind that makes people do something without knowing why they do it, and often without knowing that they are doing it. It is the sub-rational act of a group, serving in this case, through a series of pointed unintentions, the ends of a governing class.”
