Luke 2:7

The Greek καταλύματι is the dative singular form of κατάλυμα. Literally, it means “at the place where one unbinds” (from the verb καταλύω—"to unbind" or "to untie"). In its original sense, it referred to a spot where a traveler would unyoke his or her carriage or set down their baggage—a stopping place or resting spot. Over time, this idea evolved into the meaning of an inn, lodging, or residence. See its use in Mark 14:14 as a guest room/dining place "where we may eat."
