Definition
Adverb: Used to indicate that a particular situation or action has not happened or been completed up to the present moment. It is typically used in negative statements or questions to emphasize the ongoing absence or incompleteness of something.
Usage
The phrase "as yet" is used to talk about the period of time leading up to now. It is formal and is almost always used in negative contexts (with "not" or "no") or in questions to express that something expected has not occurred so far.
Examples
- We have received as yet no official confirmation of the report.
- The cause of the problem is as yet unknown.
- Have you had any news from them as yet?
- A vaccine for the disease has not as yet been developed.
Advanced Usage
- Inversion for Emphasis: In very formal or literary contexts, "as yet" can be placed at the beginning of a clause, often requiring inversion of the subject and auxiliary verb.
- As yet have we heard nothing from the committee.
- Contrast with 'yet': While "yet" alone can be used in similar negative contexts ("We haven't finished yet"), "as yet" is more formal and often places slightly more emphasis on the temporal aspect—the continuous state of "up to this precise point."
