U+7DF4 "練" CJK Unified Ideograph-# Unicode Character
Unicode Version 17.0
練
U+7DF4 "練" CJK Unified Ideograph-# is a Chinese character that primarily means "to practice," "to train," or "to drill," and is also commonly used in the sense of "to refine" or "to polish" something, such as skills or materials. In Japanese, it is known as the kanji "ren" (as in "renshuu" meaning practice), while in Korean it is rendered as "ryeon" or "yeon" and carries similar connotations of training or tempering. Historically, the character combines the radical for thread or silk (糸) with a phonetic component, reflecting its original association with the processing of silk, specifically boiling and softening raw fibers, which evolved into the broader metaphorical usage of honing or perfecting through repeated effort.
