One of the most common mistakes in English grammar is the incorrect use of the phrase "as of yet". People often use this phrase to indicate that something has not happened or been completed up to the present moment.

Correct usage: yet

The correct phrase to use in this case is simply "yet". For example:

• Incorrect: We haven't received the package as of yet.
• Correct: We haven't received the package yet.

As you can see in the correct example, removing "as of" and using "yet" on its own is sufficient to convey the intended meaning.

When to use "as yet"

While "as of yet" is technically incorrect, there is a correct variation of the phrase that can be used in certain situations: "as yet". This phrase is used to express that something has not happened or been completed up to a particular point in time.

• Incorrect: As of yet, I haven't finished my report.
• Correct: As yet, I haven't finished my report.

As you can see, the correct usage is "as yet" without the additional "of". This phrase is often used when emphasizing that something is expected to happen or be completed in the future.

In conclusion, it's important to remember that the correct phrases to use when indicating something has not happened or been completed up to the present moment are "yet" or "as yet". The incorrect phrase "as of yet" should be avoided.
