Huh. I’m a reasonably literate native English speaker and just learned this word today. It was used a few times in this thread. (A collection of glosses is a glossary if others are similarly mystified.)
I sometimes use words that my adult children don’t know.
But I’m grateful that all of us know how to read and look up those words to improve our knowledge of the language.
By far my most popular post describes why I feel natives often dislike many of WK’s choices.
