According to the Institute of Russian Language of the Russian Academy of Sciences, an optional [[acute accent]] ({{lang|ru|знак ударения}}) may, and sometimes should, be used to mark [[stress (linguistics)|stress]]. For example, it is used to distinguish between otherwise identical words, especially when context does not make it obvious: {{lang|ru|замо́к}} (''zamók'' – "lock") – {{lang|ru|за́мок}} (''zámok'' – "castle"), {{lang|ru|сто́ящий}} (''stóyashchy'' – "worthwhile") – {{lang|ru|стоя́щий}} (''stoyáshchy'' – "standing"), {{lang|ru|чудно́}} (''chudnó'' – "this is odd") – {{lang|ru|чу́дно}} (''chúdno'' – "this is marvellous"), {{lang|ru|молоде́ц}} (''molodéts'' – "well done!") – {{lang|ru|мо́лодец}} (''mólodets'' – "fine young man"), {{lang|ru|узна́ю}} (''uznáyu'' – "I shall learn it") – {{lang|ru|узнаю́}} (''uznayú'' – "I recognize it"), {{lang|ru|отреза́ть}} (''otrezát'' – "to be cutting") – {{lang|ru|отре́зать}} (''otrézat'' – "to have cut"); to indicate the proper pronunciation of uncommon words, especially personal and family names, like {{lang|ru|афе́ра}} (''aféra'', "scandal, affair"), {{lang|ru|гу́ру}} (''gúru'', "guru"), {{lang|ru|Гарси́я}} (''García''), {{lang|ru|Оле́ша}} (''Olésha''), {{lang|ru|Фе́рми}} (''Fermi''), and to show which is the stressed word in a sentence, for example {{lang|ru|Ты́ съел печенье?}} (''Tý syel pechenye?'' – "Was it ''you'' who ate the cookie?") – {{lang|ru|Ты съе́л печенье?}} (''Ty syél pechenye?'' – "Did you ''eat'' the cookie?) – {{lang|ru|Ты съел пече́нье?}} (''Ty syel pechénye?'' "Was it the ''cookie'' you ate?"). Stress marks are mandatory in lexical dictionaries and books for children or Russian learners.<ref>{{cite web|url=https://www.researchgate.net/publication/341623843|first=Sviatlana|last=Karpava|title=Lexical stress assignment and reading skills of Russian heritage children}}</ref>
