Pronounced: TEM-puh-rize, verb
Note: This is a “borderline” word; I have run across it and had a sense of the meaning, but wasn’t quite right.
The word lustrate means
- “to purify by means of rituals or ceremonies”
- “To remove undesirable people from an organization, especially in an abrupt or violent manner”
My instincts about this word were correct; it does have the root of “light”; it comes from Latin lustrare “to make bright”. It contains the root word meaning “light”. I suppose (though the material I have doesn’t say) that when something was purified, it was brighter, and that is how that sense came to be.
This word showed up in the early 1600s.
