板

นิรุกติศาสตร์และส่วนประกอบ

The Chinese character 板 (bǎn) is composed of two parts: 木 (mù), meaning "wood," and 反 (fǎn), meaning "to turn over." This suggests that the original meaning of 板 was "a piece of wood that has been turned over." This is supported by the fact that the earliest known use of 板 was in the oracle bone script, where it was used to represent a wooden board.Over time, the meaning of 板 expanded to include other objects made of wood, such as planks, boards, and panels. It is also used to refer to flat, smooth surfaces, such as the surface of a table or the ground. In addition, 板 is used in a number of figurative expressions, such as 一板一眼 (yībǎn yīyǎn), which means "rigid and inflexible."The character 板 is pronounced bǎn in Mandarin Chinese. It is a fourth-tone character, which means that it is pronounced with a falling tone.
