The character 苦 evolved from ancient pictographs depicting plants. Its original form in oracle bone script showed a plant with leaves, representing vegetation. By the bronze script period, it developed into its modern structure with the grass radical (艹) on top, indicating plants, and the component 古 below, which provides phonetic value but also carries connotations of 'old' or 'enduring.' Together, these elements create the meaning of 'bitter' - originally describing the taste of certain medicinal herbs and plants. Over time, the character's meaning expanded metaphorically to include hardship, suffering, and difficulty, reflecting how bitter experiences, like bitter medicine, can be endured for eventual benefit. Arrived in Japan: The character 苦 likely arrived in Japan during the 5th-6th centuries CE, when the Japanese writing system was being developed through cultural exchange with China. It was introduced as part of the kanji system along with Buddhist texts and Chinese classics, where it appeared in compounds describing the Buddhist concept of suffering (苦悩) and in classical Chinese literature.
