@kazarnowicz I am a native speaker, and I suspect that I have an unusually large vocabulary, but I got that from reading a lot, and these days if you read on any kind of e-reader device you can long-press on a word to define it. I suspect that most people won't know the word but in most contexts I can imagine using it the meaning should be clear enough.

Unlike, for example, the words "bemused", "quizzical", "nonplussed" or "easterly", where you get sentences like, "Harold gave Jane a bemused look", and you don't know if the author is in the group of people who know the "correct" meaning or the group of people who thinks it means the thing it sounds like it means.
