Dear list,
As it turns out, my workaround here is subpar since it inserts an undesired
line after the description block.
Hans was very kind to send me a fix to place in cont-new.mkxl that fixes the
issue. However, due to my errors in properly pasting the fix correctly, it did
not work. I updated LMTX today and the fix is already merged.
I am pasting below Hans' fix for reference (for anyone who might come across
this later) –

Dear list,
Although, not a fix for the issue, here is a workaround that allowed me to
achieve what I wanted:
\definedescription[amnata]
\setupdescription[amnata]
[closesymbol={},
closecommand=\wordright,
before=\startamnatanarrower,
after=\stopamnatanarrower]
\startamnata
A quote from another author : Suppose that thereisalongwordhere.
\wordright{– author}
\stopamnata
With this the argument of \wordright appears correctly at the right-edge of
the block. Note that this does not work (as expected) when closesymbol is not
set (or, is empty). Therefore, here I have set closesymbol={U+200B}, which
is the zero width space.
Thanks,

Dear Benjamin and Hans,
Thanks for your responses.
I did not mention this in my initial question but I am not exactly doing
'author' in the last line. Instead I usually do
\cite[alternative=authoryears,righttext={Ch. 12}][author1992].
That is, almost always, I need to refer to a specific chapter/page number in
the work. The issue with this and \hfill is that the 'righttext' part gets
nudged into the next line.

When the penultimate line inside the block breaks without hyphenation, then
argument of \wordright is typeset as expected (i.e. in the same line).
On the other hand, when the penultimate line inside this block breaks with
hyphenation, the argument of \wordright is pushed to the next line even when
there is enough space for it on the same line.
Here is a sample illustrating this:
\startamnata
A quote from another author : Suppose that thereisalongwordhere.
\wordright{– author}
\stopamnata
\startamnata
A quote from another author : Here, the text does not cause
hyphenation in the first line.
\wordright{– author}
\stopamnata

How do I ensure that this does not happen, if that is possible at all? I
suppose this is expected behaviour but I am not able to understand why.

suppose this is expected behaviour but I am not able to understand why.

[NTG-context] Defining \qed (was: Bug with \wordright...)
Hi Wolfgang,
Thanks for your explanations and the correct definition of the close symbol in
an enumeration.
Following up the discussions with Hans, in order to put a close sympbol at the
end of a formula, I have the following for the definition of \qed:
%% begin example-qed.tex
\showframe
\definesymbol[Fin][\mathematics{\square}]
\def\qed{%
\ifmmode
\inrightmargin{\hskip-7.5mm\symbol[Fin]} % --> attention here
\else
\dontleavehmode\wordright{\symbol[Fin]}
\fi}
\setupformulas[location=left]
\starttext
One sees that
\placeformula
\startformula
a^2 + b^2 = c^2
\stopformula
which is the Pythagoras theorem. \qed
Another proof of Pythagors theorem is based on the figure below in which one
sees that:
\placeformula
\startformula
(a+b)^2 = c^2 + 2ab \quad \imply \quad a^2 + b^2 = c^2. \qed
\stopformula
\stoptext
%% end example-qed.tex
Now how can I replace « \hskip-7.5mm » (which was found by trial and error…) in
a robust manner so that the close symbols in the formulas are vertically
aligned with the close symbols in the text?
In other terms can one compute automatically the amount of negative \hskip so
that the definition is correct when one changes the font size and the layout?
Thanks in advance: Otared

[proof]
[...,
closesymbol={\symbol[\qed]}]
1. \symbol is meant to access pre defined symbols, as fallback method
when the requested symbol doesn't exist ConTeXt outputs the argument.
This fallback is in my opinion problematic because it's easy to miss it.
\starttext
\symbol[square]
\symbol[quadrat]
\stoptext
2. When you use the closesymbol for a enumeration ConTeXt uses also the
argument of the closecommand to apply something to the symbol, by
default the argument to the closecommand key is \wordright.
This means you're putting \wordright (which itself is flushed as symbol)
within \wordright which has to fail at some point.
Below is a cleaner version to put a symbol at the end of each proof. The
\blank setting in the \PlaceProofSymbol definition moves the symbol back
in the math formula to avoid the vertical space between them, you can
remove it but I would at leas use \blank[back] to get rid of the empty
line between the formula and the symbol.

Re: [NTG-context] Bug with \wordright in LMTX version 2020-08-03 14:25
Hi Hans,
Thanks for the hint which consists in adding an \ifmmode to the definition of
\qed.
However, as you suggest, one needs some other mechanism in math mode, since
with your new definition of \qed the alignment of the formula changes when one
adds this close symbol:
begin-example-qed.tex
\definesymbol[Fin][\mathematics{\square}]
\def\qed{\ifmmode\quad\symbol[Fin]\else\strut\wordright{\symbol[Fin]}\fi}
\starttext
\startformula
a^2 + b^2 = c^2.
\stopformula
\startformula
a^2 + b^2 = c^2. \qed
\stopformula
One sees that\type{\qed} in the formula changes the alignment of the formula.
\qed
\stoptext
end-example-qed.tex
Thanks a lot for everything: Otared

Hi Hans,
A file which used to be typeset correctly with the previous versions of lmtx,
now produces an error. Despite the error message being extremely cryptic:

I could guess the origin of the bug, which seems to be \wordright, but
although the following minimal example shows a bug it does not produce the same
ERROR output page:
the square ''end of proof''
\definesymbol[Fin][\mathematics{\square}]
\def\qed{\wordright{\symbol[Fin]}}
\starttext
\startformula
a^2 + b^2 = c^2
\stopformula
\qed % the problem is here

In the above example if one adds something before \qed, then the square
end-of-proof appears.
However in my real file ConTeXt ouputs an error page and says: Error !
Missing number, treated as zero.
One can debate if the old behavior was ok ... wordright is meant for
adding something at the end of a paragraph and you have none here. You
can add a \strut in your definition to force a line.
The lmtx implementation actually permit this:
\definesymbol[Fin][\mathematics{\square}]
\def\qed{\strut\wordright{\symbol[Fin1]}\wordright{\symbol[Fin2]}\wordright{\symbol[Fin3]}}
\starttext
\startformula
a^2 + b^2 = c^2
\stopformula
\qed % the problem is here
\stoptext
i'm still exploring this but it has to do with collecting stuff, as in:
\wordright{before} test \par
test \wordright{before} \par
(i'll look at the number issue which indeed looks a like a bug)

[NTG-context] \wordright{…} and hyphens
Hi,
\wordright{something} don’t like it if the preceding line have a hyphenated
word. It seems to work if one changes \allowbreak to hskip\zeropoint in the
macro-definition.
Here an example:
\mainlanguage[de]
% \unprotect
% \def\dowordright[#1]%
% {% don't change
%\groupedcommand
% {\removeunwantedspaces
% \hfill
% \allowbreak % changed back from \hskip\zeropoint
% % \hskip\zeropoint % - solves the problem
% \strut
% \hfill
% \quad % decent spacing
% \hbox}
% {\doifelse{#1}\v!right{\kern-\rightskip}{\doifsomething{#1}{\kern-#1}}%
% \parfillskip\zeropoint
% %\finalhyphendemerits\zerocount % yes or no
% \par}}
% \protect
\setupframedtexts
[width=\dimexpr.65\textwidth,
offset=none]
\starttext
\startframedtext
ein Jahr da gewohnt in Rülzheim, waren noch Schwiegereltern dabei..
\wordright{(S.\,3, Z.\,78–97)}
\stopframedtext
\startframedtext
wenn du Ro, Mund aufmachst hörst das du nicht da geboren bist (lacht
verlegen).
\wordright{(S.\,4, Z.\,117–121)}
\stopframedtext
\startframedtext
ein Jahr da gewohnt in Rülzheim, waren noch Schwie- gereltern dabei
\wordright{(S.\,3, Z.\,78–97)}
\stopframedtext
\stoptext
By the way: I can’t make a minimal example yet but I have a text where the same
word appears on one place with ligatures and on another place without. Perhaps
this is known …?
