Dear list, I have the following sample: \mainlanguage[agr] \setupbodyfont[dejavu] \starttext \startTEXpage[offset=2em] \hyphenatedword{πρᾶγμα πράγματος} \stopTEXpage \stoptext that ouputs: πρᾶ-γμα πρά-γμα-τος As far as I know, two consonants in ancient Greek aren’t hyphenated, when they may begin a word. Γν may be the beginning of word in Greek (such as γνῶσις), but even LSJ has no word that begins with γμ. Am I missing something or should this be improved in the hyphenation patterns? Many thanks for your help, Pablo -- http://www.ousia.tk

You're right, this shouldn't happen. I tried in vain to find the culprit in lang-agr.lua and to see more with \enabletrackers[hyphenator.visualize,hyphenator.steps,languages.patterns] but failed. Arthur is the guru here, so maybe he has a suggestion? Thomas

I have just discovered that LuaLaTeX (from the TeX Live version that comes with Fedora 32) does exactly the same with ancient Greek (hyphenation is fine in modern polytonic Greek). Just in case it helps, Pablo -- http://www.ousia.tk

Of course, I meant Fedora 28. Fedora 32 should be released in 2020. Pablo -- http://www.ousia.tk

All the TeX engines and formats use hyphenation pattern files that derive from a common repository that Mojca and I maintain (although I see that ConTeXt’s are slightly outdated), nothing strange here. Best, Arthur

Ah, I was going for a title that inspired more awe, like “Emperor of Hyphenation”, but guru will do for the time being :-) The reason you can’t find any obvious culprit is because you need to look at the patterns that are missing: taking πράγματσς as an example, the matching patterns are .π4 ά1 α1 ο1 4ς. that allow a break after any vowel and prohibit breaks after the first letter and before the last letter in the word (which is relevant because \lefthyphenmin and \righthyphenmin are both set to 1). Since these are the only patterns that apply, the possible hyphenation points are thus πρά-γμα-τος Digging deeper in the pattern file, you’ll see that it takes quite many two-consonant clusters into account, starting at line 267 of the master file in the repository, with a comment “other divisable consonant combinations” (https://github.com/hyphenation/tex-hyphen/blob/82e5651/hyph-utf8/tex/generic...): 2β1γ 2β1ζ 2β1θ 2β1κ ... 2γ1θ 2γ1κ 2γ1ξ 2γ1π ... You can see that γμ is not there (nor, of course, γν, which was expected). If it was, the pattern 2γ1μ would force the break πράγ-μα, hence its absence leads me to believe that the breaks before γμ are intentional. I suggest you contact Dimitrios Filippou, the main author of the patterns, to ask if it was somehow an oversight or if he was following a different rule (email address at the top of the file linked to, in a slightly obfuscated form). Best, Arthur

I thought you were the hat of hyphenation. Best, Hraban

Many thanks for your reply, Arthur. I’m going to contact Dimitrios to check what is going on here. Pablo -- http://www.ousia.tk

Since we’ve continued that discussion off list, I’d like to mention our conclusion, which is that the patterns shouldn’t be changed, since they follow a somewhat different rule, where a few additional consonant clusters receive the same treatment as γν. That rule is documented in William Goodwin’s Greek grammar, §97: https://archive.org/details/greekgrammar00gooduoft/page/24 Thomas pointed out that Goodwin’s statement that his rule was “based on ancient tradition” is not very convincing, and that different behaviours are possible, but the one reported by Pablo above is documented and intentional. Best, Arthur
