arrantyoudaoicibaDictYouDict[arrant 词源字典]
arrant: [16] Arrant is an alteration of errant, as in knight errant. This originally meant ‘roaming, wandering’, but its persistent application to nouns with negative connotations, such as rogue and thief, gradually drove its meaning downwards by association, to ‘notorious’.

nomad (n.)youdaoicibaDictYouDict
1550s, from Middle French nomade (16c.), from Latin Nomas (genitive Nomadis) "wandering groups in Arabia," from Greek nomas (genitive nomados, plural nomades) "roaming, roving, wandering" (to find pastures for flocks or herds), related to nomos "pasture, pasturage, grazing," literally "land allotted," from PIE root *nem- "to divide, distribute, allot" (see nemesis).
roam (v.)youdaoicibaDictYouDict
c. 1300, romen, possibly from Old English *ramian "act of wandering about," which is probably related to aræman "arise, lift up." There are no certain cognate forms in other Germanic languages, but Barnhart points to Old Norse reimuðr "act of wandering about," reimast "to haunt." "Except in late puns, there is no evidence of connexion with the Romance words denoting pilgrims or pilgrimages to Rome ...." [OED], such as Spanish romero "a pilot-fish; a pilgrim;" Old French romier "travelling as a pilgrim; a pilgrim," from Medieval Latin romerius "a pilgrim" (originally to Rome). Related: Roamed; roamer; roaming.
vagary (n.)youdaoicibaDictYouDict
1570s, "a wandering, a roaming journey," from Italian vagare or directly from Latin vagari "to wander, stroll about, roam, be unsettled, spread abroad," from vagus "roving, wandering" (see vague). The infinitive appears to have been adopted in English as a noun and conformed to nouns in -ary, "but this can hardly be explained except as an orig. university use" [Century Dictionary]. Current meaning of "eccentric notion or conduct" (1620s) is from notion of mental wandering. Related: Vagaries.
