The word 威力 is formed by combining two characters, each contributing a core concept to create a new, unified meaning. The first character, 威, conveys a sense of awe-inspiring authority, majesty, or intimidating presence. It is joined with the second character, 力, which simply means strength, force, or power. Their combination results in a concept where power is not merely physical or quantitative, but is qualitatively intensified by an imposing, formidable, or majestic character, thus forming the idea of "might", "formidable power", or "overwhelming force".
