President Trump has brought back the hyphen in 'anti-Semitism' in official statements and executive orders, reversing the consensus to use 'antisemitism' without a hyphen. The intention behind this change is unclear, and Deborah Lipstadt, a Holocaust scholar, finds the decision perplexing. The spelling of the term matters to many advocates, including the International Holocaust Remembrance Alliance, which authored the definition of antisemitism and promotes the unhyphenated form. The debate over the spelling of 'anti-Semitism' has been ongoing for years, with some arguing that the focus should be on combating anti-Semitism rather than the style of the term.
