Perfume terminology is heavily French because France, and Paris in particular, dominated the development of modern fine fragrance from the 17th century onward, establishing much of the industry’s vocabulary, structure, and prestige long before English-speaking markets caught up, so the original terms simply stuck.

How French became the industry’s default language

France’s fragrance dominance grew from a combination of royal patronage, particularly under Louis XIV and later courts that prized elaborate scented fashions, and the practical advantage of Grasse’s flower fields, which we cover in our answer on why Grasse became the world capital of perfume. As France’s perfume houses became the global standard-bearers through the 19th and 20th centuries, the terms they used for concentrations, eau de toilette, eau de parfum, parfum, and industry roles became internationally adopted rather than translated, much like ballet retained French terminology or cooking retained terms like “sauté”.

It’s also partly about prestige positioning; French terminology still carries an association with luxury and heritage that brands from other countries often lean into deliberately. Our what is perfume guide explains these terms properly, including our answer on what eau de toilette translates to, and the complete guide to perfume covers the industry’s history more broadly. None of this affects how a fragrance actually performs, it’s simply useful to understand so unfamiliar labelling doesn’t feel more mysterious than it needs to.
