Adelfina is an elaborated form related to Adela, ultimately from Germanic roots meaning noble. The added feminine ending makes the name feel more ornate than its shorter relatives, with a distinctly Spanish or Latinate flavor in modern perception. Beneath that embellishment lies the same old idea of dignity and high standing, a meaning that has traveled across centuries even as the form has become more decorative.
