  In the outer reaches of the Magasphere, it would be fair to say the advent of the first pope from the US has not been greeted with unbridled enthusiasm. Take Laura Loomer, the thirtysomething influencer and conspiracy theorist, whose verdict on Leo XIV was as instant as it was theologically uninformed: “Anti-Trump, anti-Maga, pro-open Borders, and a total Marxist like Pope Francis.”

Usage notes

anti- should not be confused with the prefix ante- of Latin (not Greek) origin meaning “before”. (However, anti- does exist as a variant spelling of ante- in some borrowed words, such as anticipate and antipasto, but this spelling cannot be used to coin English words.)
anti- sometimes becomes ant- before words beginning in a vowel, as does ante-: antacid.
In British English, the anti- forms are often hyphenated as evidenced by OED's many anti- entries using hyphen. However, the exact convention significantly varies.
GPO manual recommends using a hyphen when prefixing capitalized words except when usage dictates otherwise.^[1] This is matched by usual practice: anti-American or anti-Christian.
