From re- + arrange. arrange comes from Middle English arengen, from Old French arangier. Inherited from Middle English arengen, arrangen (“to draw up a battle line”), borrowed from Old French arengier, arangier (“to put in a line, put in a row”), derived from reng, rang, ranc (“line, row, rank”), from Frankish hring (“ring”), from Proto-Germanic hringaz, ultimately from Proto-Indo-European (s)krengʰ-, a form of Proto-Indo-European (s)ker- (“to turn, bend”).
