Grammar Checker for Russian Speakers
L1-aware grammar, paraphrasing, and translation tuned to the specific transfer patterns Russian speakers face when writing English — from academic abstracts to business correspondence.
What makes English harder for Russian speakers?
Russian and English share a Slavic-vs-Germanic family split, but the everyday surface — articles, tense aspect, and the present-tense copula — is where Russian-speaking writers face the most friction.
Russian has no article system, drops the present-tense copula (есть is omitted in "the house big"), and marks aspect through perfective/imperfective verb pairs rather than progressive/perfect auxiliaries. Each of those shows up in English at high frequency. Missing articles cluster around specific nouns ("We measured temperature of sample"), and missing "is/are" cluster around scientific claims ("The result significant at p < 0.05").
Russian academic style adds two more challenges. Long subordinated sentences with reflexive participles (-щий, -вший) translate as English run-ons. Flexible word order — Russian uses case endings rather than position to mark grammatical function — occasionally leaks into English as topic-fronted emphasis that reads as awkward.
Diglot's Grammar Checker is built around these Russian-L1 patterns. The article checker uses stricter thresholds for L1s with no article system; the copula checker catches dropped "is/are" before predicate adjectives; the sentence-length analyzer flags 35-word run-ons and suggests splits.
Top Russian-to-English transfer patterns Diglot catches
| Pattern | Example error | Corrected |
|---|---|---|
| Article omission before specific nouns | "We measured temperature of sample." | "We measured the temperature of the sample." |
| Missing "is/are" before adjective | "The result significant at p < 0.05." | "The result is significant at p < 0.05." |
| Uncountable noun pluralized | "These researches show..." | "This research shows..." |
| Wrong preposition (consist from) | "The sample consists from three layers." | "The sample consists of three layers." |
| Run-on with reflexive participles | "We collected data which was analyzed using SPSS and showed three trends that confirmed our hypothesis." | "We collected the data and analyzed it using SPSS. The results showed three trends that confirmed our hypothesis." |

Frequently asked questions
- Why do Russian writers drop "is" and "are" in English?
- Russian has no present-tense copula. "Дом большой" is literally "house big" — there is no equivalent of "is" in the sentence. Russian writers carry this over to English, producing "The result significant" or "The method robust." Diglot flags missing copulas as a Russian-L1 pattern and suggests the correct form.
- Does Diglot handle long Russian-style academic sentences?
- Yes. Russian academic prose favours long sentences with multiple subordinate clauses and reflexive participles, which translate as English run-ons. Diglot detects sentences over ~35 words and suggests splits that preserve the argument while improving English readability.
- Is this useful for Russian speakers writing technical or business English?
- Yes. The Russian → English transfer patterns are the same regardless of register — missing articles, dropped copulas, wrong preposition collocations, run-on tendencies. Academic writing has the densest version; technical documentation and business reports have a lighter but identical pattern.
