The kanji 練 is a 形声文字 (keisei moji), a phono-semantic compound character. The left side is the radical 糸 (いと), meaning "thread" or "silk." The right side is 柬, which originally represented "to comb out" or "to select." The combination suggests the process of working with silk threads to refine and purify them. Over time, the meaning broadened to encompass any process of refining or practicing, leading to the general sense of "to practice," "to train," or "to polish."
