骨头

骨 (gǔ) means 'bone' and 头 (tóu) means 'head' or 'part of something.' Together, 骨头 (gǔ tou) literally translates to 'bone' and is commonly used to refer to the skeletal structure of humans or animals.

The character 骨 (gǔ) is a pictograph that originally depicted a skeleton. The character 头 (tóu) comes from the image of a human head. When combined, they form a term that specifically refers to bones in the body or animal skeletons.

骨头 is widely used in daily conversations, medical contexts, and even in idioms. For example, “他是个硬骨头” (tā shì gè yìng gǔ tóu) means 'he's a tough nut to crack.' It is also used in cooking, such as in “骨头汤” (gǔ tóu tāng), meaning 'bone soup.'
