This is one of the words I’d just never paused to think about. Auditorium. It was always just the place we went to in school when the whole school needed to meet.
But last week my husband went, “Oh! I’d never looked at auditorium this way before. As in, auditory. Plus um. Latin.”
To which I went, “Ooooh! Of course. Auditory. Like, a place you go to hear things.”
That is, in fact, the exact definition, directly from the Latin word for “lecture-hall.”
It’s interesting to note, however, that auditorium only dates to 1727. Before that (from the 1300s), the room/building was, in fact, called an auditory! That ranks as something I didn’t know. How about you?
