Grammar Checker for Arabic Speakers
L1-aware grammar, paraphrasing, and translation tuned to the specific transfer patterns Arabic speakers face when writing English — from academic abstracts to business correspondence.
What makes English harder for Arabic speakers?
Arabic and English mark sentences through very different grammars — articles, copulas, and clause connection all behave in ways that show up in Arabic-authored English at high frequency.
Arabic uses the definite article al- (الـ) on most contextually-known nouns, including generic concepts (al-'ilm = "the science"). Arabic writers carry this habit over and oversupply "the" before generic English nouns. Arabic also drops the copula in present-tense nominal sentences (al-bait kabir = "the house big"), so "The result significant" feels structurally complete.
Coordination is the third high-frequency category. Arabic favours and-coordination using wa- (و) over English-style subordination, so Arabic-authored English often has 4-6 "and"-linked clauses in a single sentence. Modern Standard Arabic academic register is also highly formal, which carries over as stilted English ("It is worth mentioning that..." opening every paragraph).
Diglot's Grammar Checker is calibrated for these Arabic-L1 patterns: the article checker flags over-supplied "the" on abstract nouns, the copula checker catches dropped "is/are," and the sentence-length analyzer detects run-on coordination chains.
What Grammar Checker specifically does for Arabic writers
An Arabic-aware grammar checker is calibrated against two equal-but-opposite errors: «the» over-supplied where English wants the bare noun, and «is/are» absent where English requires the copula. Arabic writers using al- (الـ) on every generic noun produce «The science is the foundation of the human progress» — five articles where English wants zero. A general-purpose checker treats each «the» as locally grammatical; Diglot reads the cluster shape and surfaces the Arabic-pattern over-supply rather than treating each instance as an independent flag.
The second category Arabic writers benefit from is the wa-coordination run-on detector. Arabic favours coordination with «و» (wa-) over English-style subordination, so Arabic-authored English chains 4-6 clauses with «and» in a single sentence: «We collected the data and we analyzed it and we found three trends and they confirmed our hypothesis.» Diglot flags long «and»-chains as an Arabic-L1 pattern and proposes structural splits that preserve the meaning. The relative-clause checker handles the third pattern — resumptive pronouns («The sample which we collected it») that are grammatical in Arabic but redundant in English.
Top Arabic-to-English transfer patterns Diglot catches
| Pattern | Example error | Corrected |
|---|---|---|
| "The" over-supplied on generic nouns | "The science is the foundation of the human progress." | "Science is the foundation of human progress." |
| Missing "is/are" before adjective | "The result significant at p < 0.05." | "The result is significant at p < 0.05." |
| Run-on from wa- coordination | "We collected the data and we analyzed it and we found three trends and they confirmed our hypothesis." | "We collected the data, analyzed it, and found three trends that confirmed our hypothesis." |
| Resumptive pronoun in relative clause | "The sample which we collected it last week showed contamination." | "The sample we collected last week showed contamination." |
| Transitive verb with extra "about" | "We discussed about the implications in the next section." | "We discussed the implications in the next section." |

Frequently asked questions
- Why do Arabic writers oversupply "the" in English?
- Arabic's definite article al- (الـ) attaches to most contextually-known nouns, including generic abstract concepts (al-'ilm = "the science"). Arabic writers carry this habit over to English, producing "The science is the foundation of the human progress." English uses no article for generic mass nouns. Diglot flags the over-supply as an Arabic-L1 pattern and suggests the correct bare form.
- How does Diglot handle Arabic-style long sentences?
- Arabic favours coordination with wa- (و) over subordination, so Arabic-authored English often chains 4-6 clauses with "and" in a single sentence. Diglot detects long sentences with 3+ "and" coordinators and suggests structural splits that preserve the meaning while improving English readability for reviewers.
- Is Diglot useful for Modern Standard Arabic writers, dialect speakers, or both?
- Both. The English transfer patterns operate at the level of grammatical systems that all Arabic varieties share — al- definite article, present-tense copula omission, wa- coordination preference, resumptive pronouns in relative clauses. Whether the writer's spoken Arabic is Egyptian, Levantine, Gulf, or MSA, the English issues are the same.
- Does the grammar checker recognise the «the» over-supply pattern as Arabic-L1 specifically?
- Yes. The pattern `article-over-supplied-generic` is in the Arabic-aware ruleset because Arabic's definite article al- attaches to most contextually-known nouns including generic abstractions («الـعِلْم» = «the science»). Arabic writers carry this habit directly to English. Diglot flags clusters of unnecessary «the» on generic mass nouns and explains the underlying Arabic article-system reason instead of presenting it as a syntactic typo.
- Will it detect wa-coordination chains as run-ons rather than as five grammatically-correct «and» linkers?
- Yes — that's one of the highest-impact Arabic-writer patterns Diglot catches. The checker reads sentence-level shape, not just word-level grammar. A sentence with 3+ coordinated clauses linked by «and» is flagged as an Arabic-pattern wa-coordination run-on, with suggested subordinations that preserve causal and temporal logic without preserving the coordination weight.
