The Chinese word **存储** is formed through the process of **compounding**, where two independent morphemes with related meanings are combined to create a new, more specific term. The first character, **存** (*cún*), carries the core meaning of "to exist," "to preserve," or "to store." The second character, **储** (*chǔ*), means "to save up," "to accumulate," or "to reserve." When paired, their meanings reinforce and specialize each other, evolving from the general concept of "saving and holding" to specifically denote **"storage,"** most commonly in the modern context of data or information storage (e.g., in computing). This formation is typical of modern Chinese technical vocabulary, where classical roots are combined to describe new concepts.
