The word 丑陋 is formed by combining two characters, each contributing a related meaning to create a unified concept. The first character, 丑, directly means "ugly" or "disgraceful". The second, 陋, carries meanings of "coarse", "vulgar", "mean", or "humble". When paired together, they do not merely add their meanings but fuse them into a single, intensified idea of repulsive ugliness, where 陋 deepens 丑 to imply a kind of ugliness that is not just in appearance but also in character, a vulgar, coarse, and offensive unsightliness.
