Pronounced: AL-uh-zon, noun
Notes: I definitely did not know this word or its source
The word legerity means “alert facile quickness of mind or body”
Background / Comments
The word has the idea of being quick or light on one’s feet. It comes from words in Middle French, Old French, and Latin that all mean “light in weight”. These days, the word also refers to being nimble in mind. I find that people who exhibit nimbleness of mind seem to be young, regardless of their appearance.
This word showed up in the mid-1500s.
