"Nouveau roturier" is a term that refers to a newly wealthy person who has very recently gained wealth through their own efforts rather than by inheritance or noble birth. Some synonyms for "nouveau roturier" include "upstart", "parvenu", "new money", "social climber", and "arriviste". These words are often used to describe people who appear to be trying too hard to fit in with the upper class, often by flaunting their wealth and trying to emulate the manners and dress of the nobility. While these synonyms are often used in a negative context, it is important to note that there is nothing inherently wrong with being a "nouveau roturier". After all, everyone deserves the opportunity to succeed and improve their social standing.
