Origin

Late 16th century; earliest use found in Henry Lyte (1529–1607), botanist and antiquary. From the name of the river Rhine + berry, after early modern Dutch rijnbesie; the first element in the Dutch word probably in fact shows a folk-etymological substitution of the river name for Middle Dutch, early modern Dutch rein ridge forming the boundary of a field, boundary marker; compare similarly German Rheinbeere beside Rainbeere.
