Words You Don't Hear Every Day

Words are kind of funny if you stop to think about it. Some words are common in everyday use. Some words are uncommon and are only heard in a few places. I've been thinking about that lately.

Supernal is one of those words. I've only heard it at church, and even then, only rarely. It seems to be one of those words that is confined to a specific context. I hear its synonyms, such as ethereal, divine, or heavenly in other places, but I'm sure people would give me a funny look if I described the school cafeteria's tofu chocolate mousse as supernal. [1]

Another word that seems confined to certain circumstances is salacious. I primarily hear this word in class discussions. (I have heard it elsewhere, but only rarely. More common are its synonyms - risque, racy, etc. However, even less common is its synonym, lascivious. I've only ever seen that one in the Bible.) I recall its use at least twice this semester, in different classes, by different professors. The first time was in my appellate advocacy class when we were discussing statutory interpretation. We were reading a case that the professor handed out. [2] As he passed it out, he said that it was a bit salacious, but it was nonetheless a good case to illustrate the point he was trying to make. [3] The second occurrence was today in my constitutional law class. We were discussing the constitutionality of restrictions on commercial speech. Some divorce lawyers in Chicago placed a prominent billboard advertising their services. The billboard had some racy pictures on it, and the professor was trying to spark discussion by asking us if it mattered that the advertisement was salacious.

What words do you hear in certain contexts but not in others?

____
1. It's really tasty, though. Not quite supernal, but certainly heavenly.
2. See People v. Gibbons, 215 Cal. App. 3d 1204 (1989).
3. The point he was trying to make is that statutes aren't self-interpreting, and that even a seemingly simple word like "communication" is subject to people arguing about it.
