Origin

The character 紋 combines silk thread or fabric on the left with a sound hint on the right. Since the character deals with patterns and designs, the silk radical makes sense—decorative patterns were often woven into or applied to fabric, especially in crests and ornamental designs. The right component is primarily a sound hint that helps indicate the pronunciation, not the meaning. Over time, this combination came to represent decorative patterns, family crests, and other figured designs, particularly those that appear on textiles.
