Sephardic has come to mean almost any Jew who is not Ashkenazi, however this is erroneous. Although there are wide cultural divergences within the Sephardic world, common liturgy and religious customs constitute underlying factors of unity. The academic term is that Sephardim are the Jews from Iberia (Spain and Portugal). The plural term is Sephardim; the singular is "Sephardi." The Hebrew "Sephardi" or "Sepharadi" refers either to a single Iberian Jew.
