Tenacity

A rare virtue-style name, associated with determination and dedication to a particular cause or goal, with having a strong grip, and with an enduring existence. This could be spun positively and associated with hard work and focus, but there may also be an undertone of negativity to the word name, a degree of being too dedicated to one goal or of something, such as a myth, enduring for just too long.

Similar in sound to Felicity and in meaning to Constance, it could make for an interesting middle name.

Pronounced teh-NAS-ih-tee.
