The word "晕倒" is formed by combining two characters, each contributing a core meaning to create a new concept: "晕" conveys the state of dizziness or lightheadedness, while "倒" conveys the action of falling or collapsing. When merged, these characters depict a natural sequence where dizziness leads to a fall, thus collectively expressing the idea of fainting or swooning. This formation relies on the semantic fusion of the characters' individual meanings to illustrate a cause-and-effect relationship, resulting in a compound that vividly captures the physical act of collapsing due to dizziness.
