Many of my students struggle with spelling, reading and writing; and often, Culinary topics/techniques/equipment have French names which can seem overwhelming. These French words like "mise en place" are an industry standard, so they need to learn these terms and how to use them when speaking in their work environment. I agree that repetition is crucial in helping students overcome their fear of speaking a different language and start to use those words with more confidence and understanding. Giving concrete examples and using the words in a variety of contexts is key.
