Expert writing Tips

Best practice

Use "as of" to clearly specify the date or time from which a statement or condition is valid. This avoids ambiguity and ensures clarity, especially in formal writing.

Common error

Avoid using future tense verbs immediately after "as of" if the intended meaning is to describe a state that is already in effect. For example, instead of "As of tomorrow, the project will be completed", write "As of tomorrow, the project is completed" or "As of tomorrow, the project should be completed".

Linguistic Context

The phrase "as of" primarily functions as a prepositional phrase, introducing a temporal reference that specifies the point from which something is valid or effective. As Ludwig AI confirms, it indicates when something began or started. It is used to anchor a statement in time, providing a clear temporal boundary.
