Today's word

boniface \BAH-nuh-fuss\ - the proprietor of a hotel, nightclub, or restaurant

I was familiar with the name, but not the word.

hypnagogic \hip-nuh-GAH-jik\ - of, relating to, or occurring in the period of drowsiness immediately preceding sleep

I figured this one had something to do with sleep.

dun - an urgent request; especially : a demand for payment

I was completely unfamiliar with this dun.
