The word "farewell" originated in Middle English as a combination of "fare" (to travel) and "well" (prosperously). It originally functioned as a phrase meaning "may you travel safely/prosperously," later condensed into a single term for parting greetings. The logic reflects a wish for the departing person's safe journey, preserving the literal sense of "go well."
