My own love affair with the French language and France began in middle school. At that time, I would borrow books from the library to learn the language. As a former employee of the Librairie de France in New York City during the early 1990s, I had the opportunity to meet many people from France and other French-speaking countries. It was a great time, for I got to improve on my French and meet many interesting people.

I’d also attend weekly language exchange sessions at locals throughout the city. These clubs were founded by renowned radio host and linguist Barry Farber, and I had a great time speaking French with natives and Francophiles. Needless to say, my love for the French language has remained strong throughout my life, and even though I’ve never used these words in actual conversation, they’re great to know and can even impress a native. I’m happy to share them with you.
