Hi Ursula, I think you mean the so-called end of the proof sign, or QED (Quod Erat Demonstrandum). You can use this: \definesymbol[QED][\mathematics{\square}] \def\qed{\wordright{\symbol[QED]}} \starttext This is the end of our proof. \qed \stoptext In principle it is included in ConTeXt, but it seems that in the latest version I have (2024.01.23), the command \qed is broken. Best regards: Otared

I am at Home and have the following example.:
\starttext \margintext {1.1.1} {\bf Beispiel 3.2.17 (Vertauschung von All- und Existenzquantor).} \par {\it Sei M die Menge aller Männer und F die Menge aller Frauen. Die Aus-\par sage h(m, f) sei ”m ist verliebt in f“. Unter diesen Voraussetzungen machen Sie sich die Bedeutung der beiden Aussagen klar.\startalignment[right]\square\stopalignment}\stoptext}
There should be a sign like this □ at the end of the proof.
