Hi, please have a look at the following minimal (4 text-lines): \hyphenation{Er-gän-zungs-lie-fe-rung} \showframe \starttext Text text text text text text text text text text text text text text text 26.\,Ergänzungslieferung% this should brake after Ergän- Text text text text text text text text text text text text text text text 26.|\,|Ergänzungslieferung% this does brake after Ergän- Text text text text text text text text text text text text text text text text 26.|\,|Ergänzungslieferung% this should NOT brake after 26. Text text text text text text text text text text text text text text text text 26.\,Ergänzungslieferung% this does NOT brake after 26. \stoptext I need a thinspace that prevents line-break between "26." and "Ergänzungslieferung". On the other hand this thinspace shouldn't kill my hyphenation points (i.e. the word should stay breakable)! Any idea? Thanks, Steffen
