Meaning
The kanji 塊 (katamari) denotes a 'lump,' 'mass,' 'clod,' 'chunk,' or 'cluster.' It describes a solid, often shapeless or irregularly formed piece of something concrete, like earth, meat, or ice. Interestingly, it can also refer to abstract concepts, such as a 'lump of courage' (勇気の塊, yūki no katamari). Essentially, 塊 emphasizes the physical aggregation or solidification of material into a discernible unit.
Etymologically, 塊 is a phono-semantic compound character. Its left part, 土 (do, tsuchi), serves as the semantic component, clearly indicating a connection to 'earth,' 'soil,' or 'solid ground.' This directly links to its meaning of a 'clod of earth' or a 'mass of material.' The right part, 鬼 (ki, oni), is the phonetic component, primarily providing the character's on'yomi reading 'カイ' (kai) or 'ケ' (ke, though less common).
While 鬼 literally means 'demon' or 'ghost,' in this context, its main function is phonetic. However, one can also envision a conceptual link to 鬼, as it often represents something substantial, formidable, or even unrefined and large. This subtle connection reinforces the idea of a significant 'lump' or 'mass.'
Visually, the combination of 土 (earth/soil) with 鬼 (often associated with something large or primal) evokes the image of a substantial, perhaps unformed, block of material. It’s not a finely crafted object but rather a natural aggregation. This Jōyō kanji has 13 strokes and is classified as Secondary School-level (Grade S), making it important for those pursuing advanced Japanese literacy.

Memory Tip
To remember 塊, focus on its two main components: 土 (earth) on the left and 鬼 (oni, demon/ghost) on the right. Imagine a huge, formidable, perhaps even monstrous, lump of earth blocking your path—a 'demon-clod' or 'ghostly mass' of dirt. The 土 clearly signifies the 'earth' aspect of a clod, while the 鬼 hints at something large, unyielding, and shapeless, much like a formidable lump or mass. Therefore, visualizing a 'demon-like lump of earth' (土鬼) can help you recall the meaning of 'lump' or 'mass.'
