The word "束缚" is formed through the combination of two characters, each contributing a similar core meaning to create a single, intensified concept. "束" depicts the image of tying or binding something with cords, as seen in its ancient pictographic form resembling a bundle wrapped with rope. "缚" also carries the meaning of tying up or binding securely. When paired, they do not contradict or diverge but instead reinforce and compound the same fundamental idea of restriction and confinement. This synergistic pairing creates a word whose meaning is more resonant and vivid than either character alone, effectively conveying a sense of being tightly fettered, constrained, or held captive, whether in a physical, psychological, or metaphorical sense.
