Where did the term room and BOARD come from?

The term "room and board" originates from the provision of accommodation and meals. "Room" refers to the lodging aspect, while "board" comes from the old practice of serving food on a wooden board or table. Historically, this phrase was used in contexts such as inns and boarding houses, where guests paid for both their stay and meals. Over time, it has come to signify the combined cost of housing and food in various living arrangements.
