Origin

The character 頑 combines a head radical on the right, which groups it with words about the head and mind, with a sound component on the left that hints at how to pronounce it. The meaning developed from the idea of a head or mind that is immovable and unyielding — someone whose thoughts are fixed and hard to change is stubborn or foolish. The visual arrangement places the classifying element (head) where it naturally belongs in the character's structure, while the sound component signals the pronunciation without contributing to the core meaning.
