Croisé and Effacé

常常分不清這兩個位置/方向.

Croisé [kmJah-ZAY]

Crossed. The crossing of the legs with the body placed at an oblique angle to the audience. The disengaged leg may be crossed in the front or in the back.

讓觀眾看到腿是交叉著的.

Effacé [eh-fa-SAY]

Shaded. The dancer stands at an oblique angle to the audience so that a part of the body is taken back and almost hidden from view.
Also known as ouvert.

就好像收藏了身體一半不讓觀眾看到.
