The Spanish word 'caravana' comes to us through French 'caravane', which ultimately derives from the Persian word 'karvan' (کاروان), meaning 'line of pack animals'. This Persian term originally referred to a group of travelers, merchants, or pilgrims journeying together with their pack animals for safety while crossing deserts or traveling long distances. The word maintained this basic meaning as it traveled through various languages to reach its current Spanish form.

While 'caravana' itself is a relatively common Spanish word, there aren't many simpler or more basic Spanish words that share its Persian etymology. This is because it entered Spanish as a complete borrowed word rather than developing from Latin roots like many Spanish words.

English speakers will readily recognize the cognate word 'caravan', which shares the exact same etymology. In British English, 'caravan' can also refer to what Americans would call a 'trailer' or 'mobile home', though this is an extension of the original meaning. The word 'van' as in a type of vehicle is actually a shortened form of 'caravan', though many English speakers might not realize this connection!
