Interesting how different folks have different experiences for base vocabulary. “Fitful” is a word I’ve probably known since ... heck, I cannot recall when I learned it. Alternatively, I was in my 20s when offered a lasagne for a cough and had no idea what the person was offering. The room looked at me quizzically until I realized it was what I’ve always called a cough drop. Similar with “faux pas” when I first heard it around the same age. And laniard.
