# Letters that end inflected forms: two parts of a hyphenated word that end with the same one both inflect
# («учеными-энтузиастами», «языку-предку»), and the word splits at the hyphen (Universal Dependencies guidelines
# for Russian: a compound is one token only if its first part does not inflect). «о» is left out: it ends the
# first part of adjective compounds («северо-западный»).
