Meaning
The kanji 激 (GEKI, hage.shii) captures the essence of violence, intensity, extremism, strength, and agitation. It describes powerful, sudden, or profound phenomena, whether these are physical forces, emotional states, or abstract concepts. For instance, imagine a raging river, a sudden, sharp pain, or an intense debate.
Its etymology reveals it is a phono-semantic compound. The left-hand radical, 氵 (sanzui), is the "water" radical (水), serving as the semantic component. This indicates the kanji's meaning relates to water and strongly suggests a visual origin in powerful, turbulent water like rapids or a flood. The right-hand component, 亟 (KYOKU), acts as the phonetic component and also means "urgent" or "immediate." When these two elements combine, they evoke water moving with great urgency and force, leading to the broader meanings of intensity and extremity. This visual connection intuitively links to the idea of profound and often rapid force and action.
This Jōyō kanji has 15 strokes. As an advanced character, it isn't assigned a specific elementary school grade. Instead, it's typically learned at the secondary school level, making it essential for JLPT N1 proficiency.

Memory Tip
To remember 激 (GEKI, hage.shii), visualize its components. On the left is 氵 (sanzui), the "water" radical. On the right, we find 亟, signifying "urgent" or "immediate." Imagine a river where the water flows with such extreme urgency and immediacy that it creates a powerful, turbulent, and "violent" current. This mental image of swiftly moving, agitated water serves as an excellent mnemonic for the kanji's core meanings of intensity, fierceness, and extremity. So, when you see 激, think of water moving with intense, urgent force, mirroring strong emotions, drastic changes, or powerful actions.
