The word 智力 is formed by combining two meaningful characters: 智, which means "wisdom", "knowledge", or "intelligence", and 力, which means "power", "strength", or "capacity". When these two are joined, they create a new, integrated concept that is more than the sum of its parts, specifically, the "power of intelligence" or the "capacity for mental ability", which we understand as "intelligence" or "intellectual capability". This is a common pattern in Chinese where two independent, conceptual building blocks are fused to express a single, more complex abstract idea.
