用来

用来 is a prepositional phrase used to indicate the purpose or function of something. It literally means 'used for' and is often used to explain what something is intended to do.

The character 用 (yòng) means 'to use,' and 来 (lái) means 'to come' or 'to arrive.' Together, they form a fixed expression that indicates the purpose or intention behind an action or object. This construction is common in both spoken and written Chinese.

用来 is frequently used in daily conversation and writing to clarify the function of tools, methods, or actions. For example, it can be used to describe what a tool is used for, or what a process is intended to achieve. It is also often seen in instructions, descriptions, and explanations in various contexts.
