Where does the expression “je ne sais quoi” come from?
Despite its recent international popularity over the last two centuries, the expression “je ne sais quoi” is actually several thousand-year-old. In fact, it has its roots in Latin and Old French. According to its etymology, “je ne sais quoi” comes from the Old French “ne sai quoi” which meant “something”.
This phrase is itself a translation of the Latin expression “inane nescio quia” first found in one of the 37 volumes of the encyclopedia L’Histoire Naturelle, published in 77 BC by Pliny the Elder (Roman writer, philosopher, historian, and naturalist). Like the French version, the Latin origins of “je ne sais quoi” gave rise to the Spanish (un “no sé qué”) and Italian (un “non so che”) versions of the expression, which are also used in the same way.
The French version of the expression began to be introduced into the English language in the 17th century when the author Thomas Blount chose to include the expression in his work Glossographia. In this work, which could be described as a dictionary, the British author compiles and explains the foreign terms and expressions found in the English language.

The use of the expression “je ne sais quoi” in English
In other countries, especially in the United States and the United Kingdom, “je ne sais quoi” is always used as a noun phrase to designate something that is difficult to express and/or describe. The expression is then exclusively introduced by determiners like “a” (“un” in French), and by possessive adjectives like “his/her” (“son/sa” in French).

In the Anglo-Saxon culture, the expression is often associated with the French woman, and more specifically with the chic and glamorous actresses of the 60s like Brigitte Bardot or Catherine Deneuve.
