The Chinese word 思绪 (sīxù) is a compound noun formed by combining two characters: 思 (sī), meaning "to think" or "thought", and 绪 (xù), which originally means "the end of a thread" and by extension signifies "the beginning of a matter", "order", or "mental state". Together, they create a metaphorical meaning where thoughts are likened to threads; 思绪 thus refers to the "train of thought", "flow of ideas", or one's "feelings and thoughts", often implying a certain continuity, sequence, or even a tangled or sentimental state of mind. The formation exemplifies how Chinese compounds often combine concrete imagery (绪 as a thread) with an abstract concept (思 as thinking) to evoke a nuanced psychological or emotional concept.
