Definition
耐久 describes something that can withstand wear, pressure, or use over a long period without breaking down. It's a stative verb (s.v.) meaning 'to be durable' or 'to last long' — you can use it to talk about materials, products, relationships, or even abstract qualities like patience. Unlike 持久 (chíjiǔ, 'enduring over time'), 耐久 emphasizes resistance to damage or decay.
