Why this word is great
CIRCUMNAVIGATOR — [Noun] A person who sails around the world. From Latin circum- ("around") + navigare ("to sail") + -or (agent noun suffix). Unlike "explorer" (which suggests discovery of the unknown) or "voyager" (which implies open-ended travel), "circumnavigator" denotes the deliberate, almost ritualistic completion of a closed loop. It is the salt-crusted logbook with the final longitude matching the first, the bleached sails slackening as the prow crosses its own wake, the weary triumph of returning to a place that is no longer the same—proof that the world is round, and so is time.
