The word “Holocaust,” from the Greek words “holos” (whole) and “kaustos” (burned), was historically used to describe a sacrificial offering burned on an altar. Since 1945, the word has taken on a new and horrible meaning: the ideological and systematic state-sponsored persecution and mass murder of millions of European Jews (as well as millions of others, including Romani people, the intellectually disabled, dissidents and homosexuals) by the German Nazi regime between 1933 and 1945.
