How do you use ligatures if word stem and syllables do not coincide? I use ligatures. They are a beautiful typographic tradition and many fonts support them. Unfortunately the rules to apply ligatures are not hard and fast.
One rule says that you use ligatures only inside a morpheme [https://en.wikipedia.org/wiki/Morpheme], which seems to be a pretty difficult subject.
Another rule (of thumb) says that you do not use ligatures across syllables.
But what do you suggest, if these two rules conflict?
I came across a single example, which is in German, a language which is more prone to misplaced ligatures, as German has many words which are composed of other words, but in those cases the rules are easily applied.
Would you use a ligature in the German word 'Hüfte' [hip]?
The stem is 'Hüft-', that would mean: yes.
But the syllables are 'Hüf|te', which might say: no.
I know that this is not a TeX question per se, but I know that many TeXnicians are also typography aficinoados, that's why I am hoping for some good advice here. Am I overthinking this?
