Origin

The character combines the thread radical, which appears on the left and marks this as something made of fibers, with a sound hint on the right that tells you how to pronounce it. The thread radical on its own represents thin strands, but when you add the sound component, it creates a character specifically for thicker fiber products like ropes, cables, and hawsers. Over time, the meaning expanded beyond just physical cords to include abstract classes or categories, possibly because a "class" is like a grouping or strand that holds things together. The character literally looks like simplified strokes for thread, so readers could immediately recognize it was about fiber-based materials.
