Arrange is a word with a double border crossing. Its core — rang, meaning 'a row' — entered French from Frankish *hring ('ring, circle'), the same Germanic root behind English 'ring'. The Franks, Germanic settlers in Gaul, left their word for a circle of warriors in the French language, where it became rang ('a row, a rank'). Old French then built arangier ('to set in a row') by adding the prefix a- from Latin ad-. English borrowed this composite word in the fourteenth century, originally meaning to draw up troops in order. The meaning broadened steadily: arranging objects, then arranging plans, and by the nineteenth century, arranging music for different instruments. The word 'derange' follows the same pattern in reverse — de- plus rang, meaning to throw out of order. Throughout all these shifts, the original image persists: placing things in a ring or row, imposing order on chaos.
