Could you correct or confirm the definitions for 'yet'?

Hi teachers,
These are the definitions. Could they be shorter?
Negative Sentences:
It indicates actions that have not occurred between an indefinite period of time in the past and now, but are expected to occur in the near future.

Yes/No Questions:
It asks about the possibility that actions have or have not occurred between an indefinite period of time in the past and now, but if they have not occurred, they are expected to occur in the near future.

Thanks in advance.

Hi RTL,
You seem to be challenging linguists?.. Why find an answer when it’s already given?

“An interrogative construction that expects an answer of “yes” or “no.”
a yes–no question… is a question whose expected answer is either “yes” or “no”
A negative sentence is a sentence stating that something is incorrect or is not true .
A negative sentence does the opposite of a positive sentence.” (this one possibly the shortest).
–Again: why?..

Sorry, RTL, for misreading it:

“Use 'yet 'in negative sentences and in questions, especially when you think that the change, action, or state should happen or exist soon”

Of all existing sources, my first choice is always Macmillan: macmillandictionary.com/dict … ritish/yet
Sorry again to have misinterpreted your question.

Hi Eugene,
Thanks a lot for your help! No worries at all.
I really like the definitions in Macmillan. They’re a lot shorter than mine.
