The word 坚决 (jiānjué) is formed by combining two complementary characters, each contributing to an intensified meaning of firm resolve: 坚 (jiān) meaning "firm", "solid", or "steadfast", and 决 (jué) meaning "decisive", "determined", or "to decide". Together, they create a single, cohesive adjective that conveys a sense of unwavering determination and resolute conviction, where the qualities of steadfastness and decisiveness merge to describe an attitude or action that is both unyielding and purposefully decided. This is a classic example of a parallel or coordinative compound in Chinese, where two morphemes of similar meaning reinforce each other.
