Etymology: "Misobservance" is a plain formation: the prefix "mis-," meaning wrongly or badly, attached to "observance," which comes from the verb "observe," ultimately from Latin "observare," to watch over or attend to. The prefix is an old and productive English device, so the word needs no special backstory. It means, quite literally, a faulty attention to a rule or custom. The useful point is how the parts combine. "Observance" itself first carried the sense of keeping or celebrating a religious rite or festival, and "misobservance" follows that thread, describing a failure to keep a rule rather than simply a failure to notice it. The word is a coinage built from familiar parts rather than a term with a notable first user or a dramatic shift in meaning.
