There is a functionality Tools>Word Count that will give you a result for a selection.

There is a field {NUMWORDS} that will give you a result for the document

How to modify the field so that you get the number of words for a bookmark, say SUMMARY?

There isn't such a field. It would have to be handled with VBA.

You could find it like this

lWordCount = ActiveDocument.Bookmarks("SUMMARY").Range.Words.Count
0

Thanks

So there's no \bookmark qualifier or somesuch option within fields?

So how would one set up a MACROBUTTON field so that the lWordCount result shows up in the document; and is there a way to pass the bookmark name from the macrobutton field to to macro?

Some fields use bookmarks but most don't have any use for a bookmark. Sometimes a bookmark is optional in which case it is preceded by an option switch.
 
A Macrobutton is one way of launching a macro, but such a macro cannot take parameters. It does not need a bookmark,  but may contain or be contained in one or more bookmarks. The macro cannot automatically discover the range of the macro button that launched it.

You could have bookmarked areas whose words were to be counted each associated with a bookmarked location to display the count.

Okay

So would some macro like the following work?

"For each bookmark identifying a bookmark range (name ends in _WC) insert the word count for the range needed"?

So in the document one would have
Summary Word Count: 1111
Conclusion Word Count: 222
etc
Then bookmark "Summary Word Count: 1111" as Summary_WC etc
Then the loop can use the the portion of the name preceding _WC as the range to be counted.
Then the macro can replace the bookmark contents with the result?

Yes. It can be a bit tricky. There is no collection by partial name, so you have to walk through all the bookmarks and test the name.
It is best to readd a containing bookmark after updating to ensure that it does contain the new text. This disturbs the collection, so that it Next bookmark is the one just added. There is therefore a test to skip over that one.
    Dim bmk As Bookmark
    Dim rng As Range
    Dim strBookmarkName
    For Each bmk In ActiveDocument.Bookmarks
        If UCase$(Right$(bmk.Name, 3)) = "_WC" Then
            If bmk.Name <> strBookmarkName Then 'not the one just added
                strBookmarkName = bmk.Name
                Set rng = bmk.Range
                rng.Text = ActiveDocument.Bookmarks(Left$(bmk.Name, Len(bmk.Name) - 3)).Range.words.Count
                ActiveDocument.Bookmarks.Add bmk.Name, rng 'redefine the bookmark
            End If
        End If
    Next bmk

Beautiful
So I think line 10 should be
                ActiveDocument.Bookmarks.Add strBookmarkName, rng 'redefine the bookmark
because at that point bmk.name has been deleted.
I guess now there should be checks that if there is a bookmark bleep_WC that bookmark bleep exists and that bleep_WC does not intersect with any other bookmark.
How would one do these two things?
Then I think we are done.
Thanks

Yes it would be better to use the name from the string.

Bookmarks is one of the few collections in Word with an Exists method:

If ActiveDocument.Bookmarks.Exists("MyBookmark") Then

There is an InRange method, but that tests for one range being completely contained in another.

The snippet will test to see if two bookmarks overlap.




Function BookmarksOverlap(bmk1 As Bookmark, bmk2 As Bookmark) As Boolean
    Dim rng1 As Range
    Dim rng2 As Range
    Set rng1 = bmk1.Range
    Set rng2 = bmk2.Range
    If rng1.Start < rng2.Start Then
        If rng1.End > rng2.Start Then
            BookmarksOverlap = True
        End If
    Else
        If rng1.Start < rng2.End Then
            BookmarksOverlap = True
        End If
    End If
End Function

I see I should have asked a related question for more points as opposed to asking within the question
Sorry
