era (Latin)

Where does "era" come from?

The Latin word 'era' originated as the feminine counterpart to 'erus,' the master of a household, likely evolving from an ancient Proto-Indo-European root signifying mastery. This status is reflected in related Hittite terms like 'ishassara,' which also denoted a lady or mistress. While some theories suggest a connection to terms for inheritance, the most direct linguistic path links 'era' to a domestic authority that defined the role of a female ruler or mistress.
