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.
What Grammar Checker specifically does for Russian writers
A Russian-aware grammar checker is calibrated for the gap Russian has where English has articles, and the gap Russian has where English has the present-tense «is/are». When a Russian writer produces «We measured temperature of sample», an English-only checker reads a complete sentence and moves on; Diglot recognises the Russian-shaped pair of omissions (article + article) and surfaces both with the underlying Slavic-noun explanation rather than treating each as an isolated typo. The copula checker holds the equivalent line for «The result significant» — a sentence Russian would write the same way structurally («Результат значителен») but English requires «is».
The second category Russian writers benefit from is the run-on detector. Russian academic style favours long subordinated clauses with reflexive participles (-щий, -вший) that translate as English sentences over 35 words. Diglot flags those and proposes splits that preserve the argument structure — not collapse it into telegram-style short sentences. The preposition collocation checker handles the third category: «consist from» / «depend from» / «result on» are tracked as Russian-pattern verb+preposition errors rather than presented as generic word-choice flags.
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.
- Does the grammar checker flag «is/are» drops as a Russian-L1 pattern specifically?
- Yes. The pattern `copula-drop` is in the Russian-aware ruleset because Russian has no present-tense copula — «Дом большой» is literally «house big». Russian writers carry this directly to English, producing «The result significant» or «The method robust». Diglot flags missing «is/are» before predicate adjectives and explains the underlying Slavic reason instead of presenting it as a syntactic error.
- Will it catch wrong preposition collocations like «consist from» or «depend from»?
- Yes — that's a high-frequency Russian-writer pattern Diglot catches. Russian uses «из» (from / out of) where English uses «of» («consists of»), and «от» (from) where English uses «on» («depends on»). Each Russian-to-English preposition mapping is tracked individually so the explanation matches the actual L1 transfer — «consist from» is not just a wrong-word substitution, it's predictable from «состоять из».
