IPA: //ˈhoʊləkɔst//
KK: /ˈhoʊləˌkɔst/
A term used to describe a large-scale destruction or loss of life, particularly referring to the genocide of Jews and others by the Nazis during World War II.
The Holocaust was a tragic event in history that resulted in the deaths of millions of people.
Holocaust → It is derived from the Greek "holos" (meaning whole) and "kaustos" (meaning burnt). The term originally referred to a sacrifice that was completely consumed by fire, and it has come to signify the mass destruction of life, particularly in reference to the genocide of Jews during World War II.
Think of 'whole' ('holos') being 'burnt' ('kaustos') — this helps you remember that a holocaust refers to a complete destruction, especially by fire.
