rand (n.)

1839 in South African English, rant, "rocky ridge overlooking a river valley," from Afrikaans, from Dutch rand "edge, margin, rim," from Proto-Germanic *randaz "edge, rim, crust" (source also of Old English rand "brink, bank," Old High German rant "border or rim of a shield," German Rand "edge, border, margin," Old Norse rönd "shield-rim, shield," Swedish rand "stripe, edge, verge").

As a unit of currency, adopted by the Republic of South Africa in 1961 (see Krugerrand). Johnson's dictionary has rand "Border; seam: as the rand of a woman's shoe." The Old English cognate survived into Middle English as rand "strip or border of land."
