The Holocaust [SEP] Terminology
The term "holocaust", first used in 1895 by the "New York Times" to describe the massacre of Armenian Christians by Ottoman Muslims, comes from the ; "hólos", "whole" + "kaustós", "burnt offering". The biblical term "shoah" (), meaning "destruction", became the standard Hebrew term for the murder of the European Jews. According to "Haaretz", the writer Yehuda Erez may have been the first to describe events in Germany as the "shoah". "Davar" and later "Haaretz" both used the term in September 1939. Yom HaShoah became Israel's Holocaust Remembrance Day in 1951. On 3 October 1941 the "American Hebrew" used the phrase "before the Holocaust", apparently to refer to the situation in France, and in May 1943 the "New York Times", discussing the Bermuda Conference, referred to the "hundreds of thousands of European Jews still surviving the Nazi Holocaust".
