Hi,

in the following example I use \setbreakpoints[compound], I understood, that word-breaking would be made (or preferred) at hyphens.

There could be a perfect line break at the hyphen of "-CC", but there is no break, and instead the complete word "AA-BB-CC" is printed, then partially in the margin.

\setbreakpoints[compound]

\showframe

\version[temporary]

\starttext

.......................................................................................................................AA-BB-CC. And the next sentence.

\stoptext

Why that does not work?

It comes from the settings for hyphen, when you look at the definition \definebreakpoint [compound] [-] [nleft=3,nright=3,type=1] you can see it needs at least three characters at the left and right before a line break is inserted, When you change the settings to \definebreakpoint [compound] [-] [nleft=2,nright=2] a linebreak is inserted after the hyphen. You can also change the values only for a certain language when you add “language=…” to \definebreakpoint. Wolfgang
