Note 10 — BOOK I. FROM THE END OF THE THIRTEENTH TO THE COMMENCEMENT OF THE SIXTEENTH CENTURY.

The changes which the name Alphonso undergoes in Spanish and Portuguese may mislead persons who are not intimate with those languages. In Spanish it is indiscriminately either Alfonso or Alonzo; the latter form, however, is chiefly used in common life. In Portuguese, from the natural tendency of that language to omit the letter l, the name is invariably pronounced and written Affonso.
