Etymology

From Middle English erraunt [and other forms], from Anglo-Norman erraunt, from Old French errant, the present participle of errer (“to walk (to); to wander (to); (figuratively) to travel, voyage”), and then: from Vulgar Latin iterāre (compare Late Latin itinerāre, itinerāri (“to travel, voyage”)), from Latin iter (“a route (including a journey, trip; a course; a path; a road)”), ultimately from Proto-Indo-European h₁ey- (“to go”); and from Latin errantem, the accusative feminine or masculine singular of errāns (“straying, errant; wandering”), the present active participle of errō (“to rove, wander; to get lost, go astray; to err, wander from the truth”), ultimately from Proto-Indo-European h₁ers- (“to flow”). Doublet of arrant.
