The kanji 絶絶 is a phono-semantic compound (形声文字). The left side is the "糸" radical (糸部) which means "thread" or "silk." The right side is "刀" which signifies "knife" or "blade" and "but" or "chop". This gives us the character a meaning that is related to cutting or severing. The original meaning can be connected to the process of cutting a thread or silk. As a result, the meaning of 絶絶 evolved to encompass the broader concept of stopping, ending, or cutting off.
