When do I use 关于 vs 至于?

Use 关于 to introduce a topic (like “regarding”) at the beginning of a sentence or discourse. Use 至于 to shift to a new subtopic after a topic has been mentioned (like “as for”). If you are starting a conversation or a paragraph with the topic, use 关于; if you are moving from one topic to another related aspect, use 至于.

Can 至于 be used at the beginning of a sentence?

Rarely. 至于 usually appears after an initial topic has been established. In some informal contexts, it might start a sentence if the previous topic is implied, but for clarity it's better to follow a prior statement. 关于 is the typical choice for starting a topic.

Are 关于 and 至于 interchangeable in any situation?

No, they are not interchangeable because their discourse functions are different. 关于 sets the topic; 至于 shifts to a subtopic. Using the wrong one will confuse the listener about the flow of information.

Is there a difference in formality?

Both can be used in formal writing. 关于 is very common in official documents, reports, and titles (e.g., 关于……的通知). 至于 also appears in formal speech but is more common when contrasting or adding a new aspect.

至于 vs 关于 (zhìyú vs guānyú): topic shift vs topic introduction

关于 introduces a topic at the start of a sentence or discourse, setting the context (like “regarding” or “about”). 至于 shifts to a new subtopic in the middle of a discussion (like “as for” or “with regard to”). The key difference is discourse flow: 关于 opens a topic, while 至于 redirects attention to a related but different aspect.

Both 关于 and 至于 are prepositions that relate to topics, but they serve different discourse functions. 关于 (guānyú) is used to introduce a topic, often at the beginning of a sentence, establishing what the following discussion is about. It is equivalent to “regarding,” “about,” or “concerning.” 至于 (zhìyú) is used to shift to a new subtopic that is related to a previously mentioned topic; it often appears after the main topic has been established. The distinction is similar to “regarding” (关于) versus “as for” (至于). Understanding the discourse context helps choose the correct one.

Quando usare ciascuno

关于guān yú

about, regarding, concerning

Use 关于 to introduce the topic of a sentence or whole discourse. It is typically placed at the start of a sentence or clause to indicate what the following statement is about. Often used in titles, headings, or formal contexts (e.g., 关于这件事… 'regarding this matter…').

关于 can also be used within a sentence after a verb, though it's less common in spoken Chinese; it predominantly appears pre-verbally or at the topic position.

至于zhì yú

as for, with regard to (shifting to a new subtopic)

Use 至于 to shift from an already introduced topic to a new, related subtopic. It often appears after a previous topic has been mentioned, and it signals that the speaker is now turning to another aspect. For example: '他很聪明，至于学习态度嘛，还不错' (He is very smart; as for his study attitude, it's not bad).

至于 often carries a nuance of contrast or further specification. It can also introduce a topic that the speaker is about to comment on, but it always follows an initial context. In rare cases, 至于 can start a sentence if the previous topic is implicitly understood, but this is less common.
