ταξίδι

Etymology: From Medieval Greek ταξίδιον (taxídion), diminutive of Ancient Greek τάξις (táxis, 'arrangement, order'). Originally referred to a military expedition or mission, as soldiers would travel in an orderly arrangement. The word evolved to mean any journey. English words like 'tactics' and 'taxonomy' share the same Greek root τάξις, relating to arrangement and order.
