A woman who is a member of the nobility, ranking above a countess and below a duchess, or the wife or widow of a marquis.
The marchioness hosted a grand ball at her estate.
Marchioness → It is formed from "marchio" (from Latin, meaning marquis or lord of a border region) and the suffix "-ess" (meaning a female). The word "marchioness" refers to a female noble who holds the rank equivalent to a marquis.
Think of a 'marquis' as a nobleman ruling a border area, and the '-ess' indicates that this is a female noble, making a marchioness a woman of noble rank.
