Today's words

First, a new WOTD:

apodictic /ap-uh-DIK-tik/ - expressing or of the nature of necessary truth or absolute certainty

The Five Keys of spiritual freedom in the Unbound model of deliverance ministry have a highly apodictic quality about them. 

 Then, a couple new words in today's Dictionary Devil puzzle:

hypogeum /'high-puh-GEE-um/ - the subterranean part of an ancient building; also : an ancient underground burial chamber

I suppose this word applies to the undercroft of York Minster (or, more formally, the Cathedral and Metropolitical Church of St Peter in York), one of the most fascinating places I've ever visited because of the multiple prior buildings on the site. 

 prothalamion /'pro-thuh-LAY-mee-uhn/ - a song in celebration of a marriage

This one applies to one of my favorite pieces to self-accompany and sing or harmonize on, which was also a part of our wedding ceremony. 

Both of these words have strong hints of their meanings in their roots.
