Where Does Vivacity Come from?

Vivacity comes from the Latin vīvācitāt-, meaning "life force," and shares a root with the word vital.

What is the root of vivacious?

It's no surprise that vivacious means "full of life," since it can be traced back to the Latin verb vivere, meaning "to live." The word was created around the mid-17th century using the Latin adjective vivax, meaning "long-lived, vigorous, high-spirited."

Where does the word sprightly come from?

Sprightly comes from spright, an archaic version of the word we now use for an elf or fairy: sprite. Ariel from Shakespeare's The Tempest and the leprechaun of Irish mythology are often referred to as sprites, and it's no coincidence that both are characterized by their light, flitting movements and mannerisms.
