Not that I know of

[kadioguy]

not that I know of
used to say that you think the answer is ‘no’ but there may be facts that you do not know about
‘Did he call earlier?’ ‘Not that I know of.’

I think that the expression is something shortened. Can I take it to mean "(That's) Not (the thing) that I know of"? (Or you might have better answers.)

 

[Tarheel]

It just means that the person is speaking from personal knowledge. It means that and nothing more. (See below.)

Ron: Is Jack on the way there?
Bob: Not that I know of.

Jack might be on the way, but if he is Bob doesn't know about it.

Also: Not to my knowledge.

Or
Not that I am aware of
As far as i know

 

[kadioguy]

Or
Not that I am aware of
As far as i know

But don't you think those are something omitted? How would you write them into a full sentence, as in my post #1?

In fact that's a common spoken phrase among the natives.

Okay, it is spoken English and not meant to be a complete sentence.

If you don't mind, could you please help me write them into a full sentence? I would like to learn them that way. A phrase on its own like that doesn't make much sense to me.

It is meant to be spoken and not written.

(After work)

Jack : Is Bob joining us for dinner?
Jill : (That Bob is joining us for dinner is) Not that I know of/Not that I am aware of/As far as I know, he isn't.

Bob might have told someone later he would join the group for dinner but Jack didn't know about it.

I think that the "that" is a relative pronoun, but what is its antecedent?

How about this?

(That Bob is joining us for dinner is) Not (something) that I know of/Not (something) that I am aware of/As far as I know, he isn't.

Grammatically, you are right, but the natives don't say or even write it that way.

It's simpler to say:
I didn't know Bob is joining us for dinner.

Not that I know of makes complete sense in itself. Any attempt to change it into 'a full sentence' ends up with something that is not natural English.

We generally say native speakers, not the natives.

You seem interested in understanding this construction in depth, Kadioguy. I know of an article that may be of some assistance in your quest, though I have not studied it in full myself and cannot say that I fully understand the author's analysis. Perhaps my drawing your attention to the article here will motivate me, at long last, to read it carefully! I'm referring to Jack Hoeksema's article "Not that I know of: A polarity-sensitive construction" (Linguistics, 2017, see attached).

In scanning through the article for the syntax part, I believe that your understanding here is correct. The author doesn't just look at "not that I know of." There is a host of related expressions, including "not that I can see." Below is the sole syntax tree in the article, given for the sentence "Fred is not drunk that I can see" (page 33). Hoeksema seems to analyze the sentence as semantically equivalent to "Fred's being drunk is not included in the set of things that I can see."

I have deleted your last post, kadioguy, as it would have sidetracked this thread. You are free to start a new thread with that question.

I would expect that you could have told me before you did that. That is, leave some time for me so that I can easily copy and paste the whole content into a new thread.

I didn't make a backup of the article, so now I have to take time to think back to it and retype the content.
