Hospitality is the act of receiving guests or strangers into one's home with a warm welcome, entertainment and kindness. The word is also used as a bracket term for catering and accommodation businesses, as in the hospitality industry.
The word hospitality originated in the Latin language, from "hospitalis," then "hospitalitas," meaning hospitable. It then developed into "hospitalite" in Old French, before being adopted into Old English in its current form.
In ancient Greek culture, hospitality, or xenia, played a significant role as it was believed that the gods walked among men. This meant it was important to treat every man with respect, even a stranger, because you could never be certain of their true identity.
