"There are no accents in Russian language" (*)
wikipedia disagrees: Acute accents are also used in Slavic language dictionaries and textbooks to indicate lexical stress, placed over the vowel of the stressed syllable. This can also serve to disambiguate meaning (e.g., in Russian писа́ть (pisát) means "to write", but пи́сать (písat) means "to piss"). http://en.wikipedia.org/wiki/Diacritic
