Masculine nouns that become feminine in the pluralThe gender of foreign words is determined in one of two ways. If the word comes from a language that distinguishes gender it maintains the same gender in Italian, ex., la brochure (French.), la brochure (Italian). For languages that don’t distinguish gender it takes the gender of a related Italian word, ex., business class (English), la business class (Italian – based on “la classe”). Another way to determine gender is to base it on category: “Il New York Times” based on the Italian word for newspaper “(il) giornale” but this isn’t always full proof.

il miglio (the mile) / le miglia (the miles)
