Hi,

there's this rather new mechanism for preventing ligatures:

\startexceptions[de]

au{f-}{f}{ff}(f\zwnj f)asse

au{f-}{f}{ff}(f\zwnj f)asste

\stopexceptions

Two questions:

1. Can you have multiple \startexceptions[de] environments ? Will they accumulate ? (I'm thinking about preparing a general list of exceptions, but of course you will also want individual exceptions.)

you can find out by trying ...

Ok, it does...

Regarding the plan of preparing a list of suppressed ligatures: It seems possible to provide a word list that could just be included with input. OTOH, you'll have to include correct hyphenation for all the words in the list. Is it possible to only define the correct ligature handling in such a list without having to supply hyphenation rules as well? Denis

Well, see attached. Interestingly, it does with \mainlanguage[de]. But, not for \language[de] \enabletrackers[hyphenation.applied.visualize] \startexceptions[de] au{f-}{f}{ff}as-sen \stopexceptions \mainlanguage[de] \starttext auffassen \language[en] auffassen \language[de] auffassen \stoptext

Besides, is it intentional that this here will suppress the ff ligature?

I don't see why that should happen here. afiks it doesn't suppress
