Russian language
According to the Institute of Russian Language of the Russian Academy of Sciences, an optional acute accent (znak udareniia) may, and sometimes should, be used to mark stress. For example, it is used to distinguish between otherwise identical words, especially when context does not make it obvious: zamok/zamok (lock/castle), stoiashchii/stoiashchii (worthwhile/standing), chudno/chudno (this is odd/this is marvelous), molodets/molodets (attaboy/fine young man), uznaiu/uznaiu (I shall learn it/I recognize it), otrezat'/otrezat' (to be cutting/to have cut); to indicate the proper pronunciation of uncommon words, especially personal and family names (afera, guru, Garsiia, Olesha, Fermi), and to show which is the stressed word in a sentence (Ty s'el pechen'e?/Ty s'el pechen'e?/Ty s'el pechen'e? - Was it you who ate the cookie?/Did you eat the cookie?/Was it the cookie that you ate?). Stress marks are mandatory in lexical dictionaries and books for children or Russian learners.
