What is the Italian translation of 'You've got to be kidding'?

Answer 1

Sei un bugiardo in the masculine and Sei una bugiarda in the feminine are Italian equivalents of the English phrase "You're a liar."

Specifically, the verb sei means "(informal singular you) are." The masculine indefinite article un and the feminine una mean "a, one." The masculine noun bugiardo and the feminine bugiarda mean "liar."

The pronunciation is "seh oon boo-DJYAHR-doh" in the masculine and "seh OO-nah boo-DJYAHR-dah" in the feminine.

Answer 2

Ma stai scherzando is an Italian equivalent of the English phrase "You've got to be kidding."

Specifically, the conjunction ma means "but." The auxiliary verb stai means "(informal singular you) are busy, in the process of." The present participle scherzando means "kidding." The pronunciation is "mah steye* skehr-TSAHN-doh."

*The sound is similar to that in the English noun "eye."
