The question How do I split a word into syllables? and its answers are helpful if one speaks Russian. Unfortunately I do not speak Russian but need to hyphenate 'Churyumov-Gerasimenko' (there must be other possibilities besides the existing hyphen). Is there some online hyphenation tool or dictionary for Russian which provides hyphenation and has an English GUI?
There is a multilingual hyphenation tool online here: ushuaia•pl online hyphenation tool
It is based on the same hyphenation engine that is used in OpenOffice and can auto-hyphenate Russian words, but unfortunately can only accept words written in Cyrillic (which in your case would be Чурюмов-Герасименко).
