Something inviolate is treated as so special, or so firmly kept, that nobody is allowed to attack it, change it, or break it. Writers use it for things they want left whole: a promise, a right, a border, a person’s body, a private room. It is a formal, slightly old-fashioned word — you meet it in law, religion, and careful prose more than in the shop. Though actually, many speakers reach for inviolable instead. The two sit close together, but inviolate pictures the thing as it now stands (still untouched), while inviolable is more the rule (it must not be touched). People also stretch it: “his Sunday walk was inviolate” just means nobody was allowed to disturb that habit.
