爿

The left half of a piece of wood that has been split vertically into two parts.

Based on its oracle bone script form, it is believed to depict a bed frame standing upright, so its original meaning was "bed." The meaning of "wooden piece" or "plank" is thought to have developed later.

It is a mirror image of the character 片.

When used as a radical, it appears on the left side of characters like 將 (general), which is why it's sometimes informally called the "jangsu-jang-byeon-bu" (general-left radical). However, 將 is actually classified under the 寸 (chun, "inch") radical, not 爿.

It also resembles the character ‘뉘’ (a Korean syllable), which may cause visual confusion.
