I just used, in the one sentence, and without thinking, two words that I had no idea that I even knew:
1. Chapeau. (I didn't use an accent because I didn't know which one to use or where to put it.)
2. Lacuna. (The plural of which, but you already knew this, is "lacunae".) (Wasn't there a band called Lacuna Coil? Answer: yes. Discogs describes them as an "Italian Gothic Metal band". Which is kinda spooky because at this very moment I am listening to "Pilgrimage" by OM, who may not be Italian but are pretty damn Gothic Metal, and how often would I be caught listening to such aural sludge? (Nice aural sludge, but ...))
