"Piece of cake" refers to something extremely easy to do—something that requires little effort or skill. In Vietnamese, it's similar to “dễ như ăn bánh” or “dễ như trở bàn tay.”

When someone says a task is a piece of cake, they mean it’s very simple and not challenging. This idiom is commonly used in everyday conversation to describe tasks, assignments, or situations that the speaker finds effortless.

2. Origin of the Idiom “Piece of Cake”

The idiom is believed to originate from Cakewalks—a game created by African Americans in the 19th century. In the game, couples danced around a cake, and the best-performing pair would win it. The phrase a piece of cake eventually evolved to describe something very easy to achieve.

Some sources also credit American poet Ogden Nash, who used the phrase in his 1936 poem “Primrose Path”: "Her picture’s in the papers now, and life’s a piece of cake."

While the exact origin is debated, the cakewalk theory is the most widely accepted among linguists. Regardless of its roots, the idiom’s core meaning remains: something easy and pleasant to do.
