Elisabeth, host of a French learning channel, introduces various alternatives to the formal French expression "au revoir" (goodbye), noting that appropriate farewells depend on formality, timing of reunion, and relationship. She highlights "Fluent," a Chrome browser extension for English speakers, which gamifies French vocabulary learning by turning words on English media sites, such as the BBC, into interactive quizzes. This tool helps users learn over 1000 words without traditional studying. Returning to farewells, Elisabeth shares her favorite, "bonne journée" (good day), for its pleasant tone. She also covers informal options like "à plus" and "salut," which can also mean "hello." Additionally, time-specific expressions include "à bientôt" (see you soon), "à tout à l'heure" (see you later today), "à demain" (see you tomorrow), and the common, non-French "ciao."
