HSE Linguists Study How Bilinguals Use Phrases with Numerals in Russian
Researchers at HSE University analysed over 4,000 examples of Russian spoken by bilinguals for whom Russian is a second language, collected from seven regions of Russia. They found that most non-standard numeral constructions are influenced not only by the speakers’ native languages but also by how frequently these expressions occur in everyday speech. For example, common phrases like 'two hours' or 'five kilometres’ almost always match the standard literary form, while less familiar expressions—especially those involving the numerals two to four or collective forms like dvoe and troe (used for referring to people)—often differ from the norm. The study has been published in Journal of Bilingualism.
Russian numerals can be confusing not only for foreigners, but also for native speakers and bilinguals—those fluent in two or more languages. Some studies suggest that the grammar of a speaker’s first language—such as Nanai or Ulchi—can influence their acquisition of Russian. Other researchers, however, argue that the influence of the native language is just one of several factors.
Researchers at the HSE Linguistic Convergence Laboratory analysed how bilinguals from different regions of Russia use numerals in spoken Russian. The team processed seven collections of interviews recorded in Daghestan, Bashkortostan, Chuvashia, Mari El, Karelia, and other regions. The sample included spontaneous speech from over 180 native speakers of 21 different languages. Each collection featured recordings of natural conversations in which participants responded to the researchers' questions and shared stories about themselves, their families, and village life. Out of more than 7,000 numeral-containing phrases, the researchers selected approximately 4,000 for analysis, excluding constructions with ordinal numerals and oblique cases.
The results showed that non-standard realisations of numeral constructions in Russian are influenced not only by the native language but also by other factors such as the education level, age, and—most importantly—how frequently the expression is used in speech. The more familiar a phrase—such as 'two hours' or 'five kilometres'—the less likely it is to appear in a non-standard form. This supports the hypothesis that linguistic constructions are acquired not through formal rules but through regular usage.
Chiara Naccarato
'It cannot be said that bilinguals simply project the grammar of their native language onto Russian when they use it. Even if a native speaker grew up in an environment where numerals function differently than in Russian, it doesn’t mean they will consistently copy the structures of their native language when speaking Russian,' explains Chiara Naccarato, Research Fellow at the Linguistic Convergence Laboratory, Associate Professor at the HSE Faculty of Humanities, and co-author of the paper.
Numerals from two to four, along with collective forms like dvoe and troe, proved particularly challenging for participants and were used in non-standard forms much more frequently.

These findings are relevant not only to linguists but also to educators, as they highlight which areas of grammar require more attention. In the future, the authors plan to investigate other areas where the native language may—or may not—influence the Russian language acquisition.
The study was conducted with support from HSE University's Basic Research Programme within the framework of the Centres of Excellence project.

HSE Economists Reveal the Secret to Strong Families
Researchers from the HSE Faculty of Economic Sciences have examined the key factors behind lasting marriages. The findings show that having children is the primary factor contributing to marital stability, while for couples without children, a greater income gap between spouses is associated with a stronger union. This is the conclusion reported in Applied Econometrics.
Fifteen Minutes on Foot: How Post-Soviet Cities Manage Access to Essential Services
Researchers from HSE University and the Institute of Geography of the Russian Academy of Sciences analysed three major Russian cities to assess their alignment with the '15-minute city' concept—an urban design that ensures residents can easily access essential services and facilities within walking distance. Naberezhnye Chelny, where most residents live in Soviet-era microdistricts, demonstrated the highest levels of accessibility. In Krasnodar, fewer than half of residents can easily reach essential facilities on foot, and in Saratov, just over a third can. The article has been published in Regional Research of Russia.

Scientists Reveal Cognitive Mechanisms Involved in Bipolar Disorder
An international team of researchers including scientists from HSE University has experimentally demonstrated that individuals with bipolar disorder tend to perceive the world as more volatile than it actually is, which often leads them to make irrational decisions. The scientists suggest that their findings could lead to the development of more accurate methods for diagnosing and treating bipolar disorder in the future.
