Meaning
The kanji 壁 (かべ / へき) primarily means "wall," but can also mean "partition" or "barrier." It refers to both physical structures that divide rooms or buildings and, metaphorically, to obstacles or challenges. Its versatility means you'll often encounter it in daily Japanese, whether discussing home decor or describing personal struggles.
The kanji 壁 is a semantic-phonetic compound. The left side features the radical 土 (つちへん), meaning "earth" or "soil." This radical clearly suggests earth or soil, the material ancient walls were often constructed from, or the ground they stand upon. The right side, 辟 (ヘキ), serves as the phonetic component, lending the kanji its On'yomi reading へき. While primarily phonetic, 辟 itself carries meanings related to avoiding, warding off, or opening. These meanings subtly reinforce the idea of a wall as something that creates separation or a barrier to prevent passage. Thus, a wall is essentially a barrier (辟) made of earth (土). The visual shape indeed reflects this: an earthy base supporting a separating structure. Composed of 16 strokes, this kanji is taught in Grade 6 of elementary school in Japan, highlighting its importance for foundational literacy.

Memory Tip
To remember 壁, focus on its two primary components. The left side features the radical 土 (つち), meaning "earth" or "soil." Imagine ancient walls being built from packed earth. The right side, 辟 (ヘキ), is primarily phonetic, but you can break it down further for visualization. It contains 辛 (シン, spicy/bitter), sometimes implying hardship or difficulty, and 立 (たつ), representing a person standing. Picture someone standing firmly, perhaps trying to avoid (a nuance of 辟) something, thereby creating a barrier. Thus, you have a wall made of earth (土) that serves as a barrier (辟), keeping things out or separating spaces. Think of it as an earthy obstacle.
