Have you forgotten the French you took in high school? Are you planning a business trip to China? Or a family vacation to Rome? The days of having to invest in language tapes and books to learn to order coffee and get directions are over. For introductory phrases and an etiquette overview, look to free podcasts, apps, and online translation tools. Want to dig in deeper? Many cultural alliances offer free or discounted resources, including language lessons. For a full immersion, host a foreign exchange student or couch-surfer, or conduct a language exchange with a native speaker online or at a local coffee shop.
