I am clear whether Estonian (language code: et) is supported in ConTeXt. According to the manual ("languages-mkiv.pdf"), I should be able to see the installed languages using \showinstalledlanguages. Unfortunately, it does not seem to produce the desired table. However, a scan through the source code shows existence of './texmf-context/tex/context/patterns/mkiv/lang-et.lua' file. It looks like much of the work, such as hyphenation, has been already done. MWE 1: \usemodule[languages-system] \loadinstalledlanguages \showinstalledlanguages MWE 2: \starttext \language[et] \currentlanguage \stoptext I suppose my question is more general: what information does the user need to provide in order for a language to get support in ConTeXt? The manual states "More languages can be defined. It is up to users to provide the information." Thanks, Clyde
