While the "Romance" languages are all from Latin, the crossover from Italian to Spanish usually works, but from French to anything else; not so much. My D-I-L is from Germany and took French (and refers to it as the most worthless language anywhere). My High School Spanish is 40 old and was poor quality at its best. My dad learned to cuss in Spanish from Porter Rican women he worked with, and those words work well from New Jersey to Las Vagas in his opinion. My grand daughter is in second grade and speaks German, Texas English, Texas Spanish, and is picking up Cantonese. She understands and is understood as she pleases! By the way, I was talking with a Home Town Buffet manager a few years ago, and he told me you couldn't be in their management at all, unless you were conversational in Spanish. (That's in Ohio!)
I had tenants that spoke zero English, but I could communicate with them, because we both tried to be understood, A few pleasantries go a long way!
I had an employee from Albania, that spoke 12 European languages. He somehow couldn't understand what was expected of him for work, but understood everything about lunch and payday. Ivan
P.S. I've found everyone obeys stern commands in German, so I call it the "Language of Obedience".
