Usage of 用来
The phrase 用来 (yònglái) is commonly used to indicate the purpose or function of an object or action. It literally means "used to" or "for the purpose of." It often appears before a verb or verb phrase to specify what something is intended for.
Common Collocations
- 用来 + Verb Phrase: Indicates the purpose, e.g., 用来学习 (used for studying).
- 用来 + Noun: Specifies what something is used for, e.g., 用来切水果 (used for cutting fruit).
Nuances and Tips
用来 emphasizes the intended use or function rather than the action itself. It is often interchangeable with 为了 in some contexts but is more focused on the object’s purpose. Avoid confusing 用来 with 起来, which is a different grammatical structure.
Register and Tone
用来 is neutral and commonly used in both spoken and written Mandarin. It is appropriate in formal and informal contexts.
Summary
Use 用来 to clearly express the purpose of an object or action, especially when you want to highlight what something is meant for rather than just what it does.
