The word 能耐 is formed by combining two characters that each contribute a distinct but complementary idea of capability: 能 primarily conveys innate ability, talent, or skill, while 耐 carries the meaning of endurance, patience, and the capacity to withstand hardship. Together, they create a composite concept where true and respected competence is understood not as raw talent alone, but as that specific ability which is tempered by, and demonstrated through, perseverance and resilience over time, thus reflecting a traditional cultural ideal of sustained and reliable prowess.
