纵（縦） is a 会意字 (huiyi zi, ideogrammic compound character), composed of 糸 (mì, silk) and 从 (cóng, to follow). 糸 suggests "threads" or "lines". 从 suggests "to follow". The original meaning of 纵 (縦) depicts the vertical threads in a fabric, thus meaning “vertical” or "the warp in a weaving". Over time, its meaning expanded to encompass the general concept of “vertical direction” or “longitudinal”.
