I understand that there's probably no rule for this, but could you give some advice on using "at the point of" and "on the point of"?At the point of leaving sounds ordinary to me, Andrew. On the point of leaving sounds a little off.
Sorry, I meant unabridged Merriam-webster. It's paid versionI think you must have misunderstood something in Merriam-Webster? See this: Definition of AT THE POINT OF
so, "at the point of crying" is totally ok to you?I always use and hear at the point of X. Here is a typical sentence that uses the phrase: She was at the point of no return.
Got it! Thank youYes, it is. That sounds much more natural to me than on the point of crying.
To be on the point of doingsomething is to be just about to do it.
You may be able to express the same thing using at, but that would normally require a different construction. For example: He was at the point where he felt ready to give up.
I should perhaps add that I don’t find either of Merriam-Webster’s examples (in the link in #4) at all natural. I don’t know how they sound to AE speakers.
