U+5FCD "忍" CJK Unified Ideograph-# Unicode Character
U+5FCD "忍" CJK Unified Ideograph-# is a Chinese character (hanzi) that is also used in Japanese kanji and Korean hanja, where it carries the fundamental meaning of "endurance," "patience," or "forbearance." The character is composed of two parts: the top radical "刃" (rèn), meaning "blade" or "knife," and the bottom component "心" (xīn), meaning "heart" or "mind," which together convey the image of a blade piercing the heart, symbolizing the mental and emotional resilience required to tolerate hardship without reaction. This concept of "忍" is deeply embedded in East Asian philosophies such as Buddhism and Confucianism, where it is often considered a virtue of self control and perseverance. In Japanese culture, it is famously associated with the ninja tradition (the word "ninja" itself derives from this character, meaning "one who endures"), and it appears in common idioms like "忍の一字" (the character for patience) to emphasize the value of silent endurance in the face of adversity.
