Meaning and Usage
The character 函 primarily refers to a box, envelope, or case used to hold letters or documents. It is a somewhat formal or literary term, often seen in written Chinese rather than everyday speech.
Common Collocations
- 函件 (hánjiàn): letters or documents sent by mail.
- 函套 (hántào): a slipcase or cover for books.
- 信函 (xìnhán): formal term for letter or correspondence.
Usage Notes
函 is not commonly used in casual conversation but appears in formal writing, official documents, or literary contexts. It often implies a container or holder for written communication. When used in compounds like 函件 or 信函, it specifically relates to mail or letters.
Avoiding Confusion
Do not confuse 函 with 信 (xìn), which more directly means 'letter' or 'mail.' 函 emphasizes the container or the concept of correspondence as a whole rather than the letter itself.
