Origin of the word

Persistent comes from Latin persistens, a form of persistere, "to continue steadfastly" or "to stand firm". The verb is built from per-, "through" or "thoroughly", and sistere, "to stand" or "to set in place", which also appears in insist, resist, consist and assist. The image is of someone who stands firm all the way through. Similar words about effort and habits appear on the everyday vocabulary hub.
