The Chinese word **生锈 (shēngxiù)**, meaning "to rust," is a compound formed through a logical verb-object construction. The first character **生** means "to produce" or "to grow," and the second character **锈** specifically means "rust." Combined, they create a vivid semantic unit where **生** acts as the verb and **锈** as its object, literally describing the process of "producing/growing rust" on a metal surface. This formation is typical in Chinese for creating descriptive verbs from tangible processes.
