About "consing"

[Xue Fuqiao]

In the doc string of the function `memory-use-counts':

  Return a list of counters that measure how much consing there has been.

I don't know what the "consing" means here.  I only know that `cons' is often
used to add a single element to the front of a list.  But this seems to be
irrelevant to the topic.

And in (info "(elisp) Garbage Collection"):

 -- Function: memory-use-counts
     This returns a list of numbers that count the number of objects
     created in this Emacs session.

Does "consing" mean creating an object here?  Thanks.
