Why is the word "impeding" used as synonym for "imminent"? [closed]

As far as I can tell, every dictionary definition (example) of "impede" talks about blocking, delaying, retard in movement... "impeding" something from happening. The word seems to come from a Latin expression meaning "to shackle the feet".

And yet, I see in daily use it is very common to use "impeding" to refer to something imminent, something that will happen sooner or later, and most likely impossible to stop. Example: "the impeding demise of ...".

What's the explanation for this usage?

It is actually from “to impend” meaning to be about to happen:

impend (v.):

• "be about to happen" (usually of something unwanted), 1590s, from Latin impendere "to hang over;" figuratively "to be imminent, be near," from assimilated form of in- "into, in, on, upon".

(Etymonline)

Evidence from Google Books suggests that both “imminent” and “impending” are very common terms.
