During the General Assembly, we typically adjourn to a time certain. “Mr. Speaker, I move the House adjourn to reconvene tomorrow at 12 noon” is a typical motion.
But on the last day, we adjourn sine die. That’s Latin for “without day.” In other words, we don’t specify the next day we will reconvene.
How to pronounce sine die? When I first arrived, speakers used the preferred dictionary pronunciation of “SAYH-nee DIE.” That’s how dictionaries from Webster’s to West’s say it’s correctly pronounced.
Lately, we’ve taken on Latinate affectations, saying “SEE-nay DEE-ay.”
I much prefer the former.
Merriam Webster pronounces it two different ways. You can hear it at
