bonds, fetters
絆 centers on ties that bind, whether physical restraints like fetters or emotional connections like bonds between people.
絆 combines 糸 (thread) with 半, which likely contributes the sound and the idea of halving or tying together, suggesting bonds made of thread.
The left side is thread 糸, and the right side looks like a half 半 tied up. Picture threads binding things together, forming bonds or fetters.
For ハン, imagine a strong bond like a hand gripping tightly: hand -> ハン, and the thread 糸 ties the bond.
