The Pope innocently mispronounced a word during his weekly sermon but the mistake actually translated into what The Independent refers to as a "distinctly unholy language."

Pope Francis peered out the window of his Apostolic Palace apartment, like he does every week. Only this time, he mispronounces "caso" for "cazzo" while speaking in Italian.

The word "caso" means example while the word "cazzo" means f**k, and may also refer to the male genitalia, notes the Telegraph.

"If each of us were to accumulate wealth not only for ourselves but to put at the service of others, in this f--- [pause], in this case God's providence would manifest itself in this gesture of solidarity," the Telegraph quotes the Pope who addressed the crowd with the statement.

According to the Daily Mail, Pope Francis actually corrected himself quickly but lost to the quicker individuals who immediately reached out to dozens of Italian media websites and posted videos on Youtube.

The Argentinian Pope speaks Spanish as his first language but is also not new to the Italian language. According to his biography at the Vatican website, his parents were Italian immigrants.

"Pope Francis' native language is Spanish but he also speaks Italian, Portuguese, French, German, Ukrainian and Piedmontese (a language spoken in the Piedmont, an area in northern Italy). Of course Pope Francis is also conversant in Latin- the official language of the Holy See," says a post from Vatican.com.

The unexpected f-bomb was actually part of the Pope's appeal for a peaceful solution to the Ukraine crisis. "I make a heartfelt appeal to the international community to support every initiative on behalf of dialogue and harmony," he said.

"A heart full of longing for possession is a heart empty of God. For this, Jesus many times chastised the rich because the risk for them to seek security in the wealth of this world is high," he added before the "cazzo" slip-up.
