Meaning
The kanji 狂 (kyō) is an N1 level character with 7 strokes. It's not assigned an elementary school grade, falling instead under the supplementary Joyo Kanji category for advanced learners. This character powerfully conveys the ideas of madness, wildness, and deviation from the norm. Its core meanings include going crazy, being mad, acting frantically, or something going out of order and malfunctioning.
Etymologically, 狂 is a character whose components clearly illustrate its meaning. It's a semantic-phonetic compound. The left part, 犭 (けものへん - kemono-hen), is the radical for 'dog' or 'animal.' This radical immediately suggests a wild, untamed, or uncontrollable aspect, much like a rabid animal.
The right component, 旺 (おう - ō), primarily means 'flourishing,' 'prosperous,' or 'vigorous.' While 旺 also serves as a phonetic component, it subtly contributes to the meaning by hinting at an excessive or rampant state. When combined, picture an animal (犭) becoming so excessively vigorous or flourishing (旺) that it loses control, becoming deranged or literally 'mad.' This evokes an image of a 'mad dog' or something that has gone beyond normal behavior due to an overwhelming internal force. This visual connection helps cement the kanji's main association with mental derangement, frenzy, or mechanical malfunction.

Memory Tip
To remember the kanji 狂, break it down into its components and form a mental image. On the left, we have the radical 犭 (けものへん), which means "dog" or "animal." On the right, we have 旺 (おう), meaning "flourishing," "prosperous," or "vigorous."
Picture a wild dog (犭) that has become excessively vigorous and rampant (旺). Imagine it foaming at the mouth, eyes wide, barking madly, completely out of control. This image of an animal driven to an extreme, almost 'king-like' (旺) state of wildness, directly conveys the idea of going "mad" or "crazy." The untamed nature of the animal radical combined with the concept of something being "overly" flourishing makes the kanji's core meaning of derangement and disorder easy to grasp and recall.
