Origin & History of “show”

Show originally meant ‘look at’. Its modern senses – basically ‘cause to look at’ – did not begin to develop until the early middle English period. It comes from a prehistoric west Germanic *skauwōjan, whose German descendant schauen still means ‘look at’ (and whose Flemish descendant scauwen gave English scavenger). this in turn was derived from the base *skau- ‘see, look’, source also of English sheen and German schön ‘beautiful’. And the ultimate ancestor of *skau- was an Indo-European base which also produced Greek keein ‘observe’ and Latin cavēre ‘beware’ (source of English caution (13th c.) and caveat (16th c.)).
