Heartiest greetings!

There is yet another thing I would very much like to be sounded out on. I am most confused as to how to define and elucidate the phrase under consideration.

Thank you!

I think you mean 'There is yet another thing I would very much like to sound you out on'.

Quite so. I would very much like to hear your opinion on the issue at hand.

That's a pretty thorough and lucid explanation. I have no questions pertaining to this matter. Thank you!
