The English word doughnut is often translated as "doughnut" because it is usually circular. This word consists of dough and nut, which literally means "nuts made of dough". Why is this so?

Because it was originally shaped like a small fruit, it was called doughnut. It was not until the late19th century that doughnut with a hole in the middle appeared, but people were used to the name doughnut.
