A
van, is a word derived from
caravan which is adapted from the Persian
karwan which means a group of people traveling together (usually on a trade expedition). Another common derived word,
caravanserai is an inn (palace) where
karwans could rest and recover after the day's journey. Caravanserai were historically most commonly established along the
Silk Road.
