How do you say something like that?

“There’s a thing for which I don’t know what it is” “There’s a thing where I don’t know what it is” “There’s a thing that I don’t know what is”

or (the one which I hear people say a lot but sounds awkward:) “There’s a thing that/which I don’t know what it is”?

To be honest they all sound awkward to me to varying degrees

    I don’t think I’ve come across that before, but I’d say it depends on what is meant:

    • I don’t know what that thing is.
    • There is a thing, but I don’t know what it is.
    • There is a thing such that I don’t know what it is. I.e., I do not know what all things are.

    There may well be some other ones, but I don’t know what they might be.
