Suffix "-ón"
Is "-ón" an accepted suffix in Spanish? It exists also in French (salle / salon) and perhaps other Romance languages as well. Consider: "callejón" is a small calle, but "hombrón" is a large hombre. Does this come from Latin? How did "large" and "small" both come to be associated with "-on"? [My various college-level language dictionaries have been no help.]
