Arabic grammar checked with the reason attached
Paste Arabic and every issue is underlined where it happens, labelled spelling, grammar, punctuation or style, with the reason attached. Arabic is written in the Arabic script, right to left, and hamza, taa marbuta, the dual and the sound plurals, case endings are what a checker has to get right in it. This one shows the rule each time, not just the change, so you can accept the fix, ignore it, or learn from it.
How to check Arabic grammar
Three steps. The third is the one most checkers leave out.
1
Paste or upload the Arabic
Type, paste or drop in a document. Arabic is already selected as the language on this page; the menu above the editor also offers the variants described below. If the text turns out to be something else, the detector says so and you can change it.
2
Read the flags
Every flag is underlined in the text and listed beside it. Spelling and grammar flags are errors; punctuation and style flags are judgements, and the label tells you which is which before you decide.
3
Accept, ignore or read why
Click a flag to see the fix and the rule behind it, then accept it or ignore it. Arabic has rules that speech does not reveal, and the reason is there so the same error is not made twice.
What the checker looks at in Arabic
The parts of Arabic grammar and spelling where a checker has to know the language, not just the words.
AgreementNouns and adjectives agree in gender, number, case and definiteness (البيت الكبير, بيت كبير), with a dual form for two (بيتان) and the rule that non-human plurals take feminine singular agreement (الكتب مفيدة). Verbs agree with the subject in gender and number, and precede it in the standard sentence.
VerbsRoots of three consonants carry meaning and patterns carry grammar: كتب, يكتب, مكتوب. Verb forms I to X change meaning predictably; the subjunctive and jussive endings after أن and لم are written and marked in careful text.
Spelling and diacriticsShort vowels (harakat) are normally omitted in ordinary writing and shown only for disambiguation or in religious and children’s text; the checker does not require them. What it does require is the correct hamza (أ, إ, آ, ء, ؤ, ئ), the taa marbuta (ة) against the haa (ه), and the alif maqsura (ى) against yaa (ي).
PunctuationThe comma (،), the semicolon (؛) and the question mark (؟) are mirrored Arabic forms; the full stop is the same. Numbers may be written in Western or Eastern Arabic digits, and the text runs right to left with the digits left to right.
Capital lettersArabic has no capital letters; emphasis and proper nouns are carried by context and by the definite article.
Common mistakes in Arabic writing
Five errors Arabic readers notice at once, and what the checker does with each.
Hamza in the wrong seat
أَخذ, إِذا, سُئل, مؤمن, شيء: the seat of the hamza depends on the surrounding vowels. The most frequent error is dropping it entirely (اذا for إذا) or writing it on the wrong carrier.
ة or ه, ى or ي
مدرسة ends in taa marbuta, not haa; على and إلى end in alif maqsura, but في and كي in yaa. The dots decide, and they disappear in fast typing.
Non-human plural agreement
الكتب مفيدة (the books are useful), with a feminine singular adjective, not مفيدون. The rule catches out speakers of every other language.
Dialect verb forms in formal text
بيكتب, عم يكتب, راح يكتب are dialect. Standard Arabic writes يكتب, سيكتب. The checker names the standard form.
The dual and the sound plurals
مهندسان (two engineers), مهندسون (engineers, subject), مهندسين (engineers, object or after a preposition). The ending carries case, and the nominative is often used where the accusative belongs.
Formal and informal Arabic
Modern Standard Arabic is itself the formal register; politeness is carried by forms of address (حضرتك, سيادتكم) and by the plural of respect (أنتم) in formal correspondence. A text that slips into dialect verb forms (بيكتب) or vocabulary reads as spoken.
The checker flags a mixed register as style rather than as an error, so the decision stays yours. If a whole text needs to move from one register to the other, the tone changer rewrites it in one pass.
Who checks Arabic here
1
Students across the Arab world writing essays and applications in Modern Standard Arabic.
2
Businesses and government offices whose Arabic correspondence must read as standard, not dialect.
3
Learners of Arabic who want the hamza and the agreement explained rather than fixed silently.
Arabic grammar checker FAQs
Is the Arabic grammar checker free?
Yes. Check Arabic without an account, within the per-check and daily word allowances shown beside the editor. Signing in raises them, and Pro removes the guest limits and the ads. The pricing page lists what each plan includes.
Which Arabic does it check?
The checker targets Modern Standard Arabic, the written form shared across the Arab world. Dialect forms (Egyptian, Levantine, Gulf) in an otherwise formal text are flagged as register, not as spelling. Arabic is preselected on this page; change the language menu above the editor if the text is a different variant.
Does it correct Arabic spelling as well as grammar?
Yes, and in Arabic the two overlap. The hamza rules (أ at the start, ئ or ؤ inside depending on the vowels, ء on the line at the end), ة against ه at the end of a word, ى against ي, and the silent alif after the plural -وا are the errors the checker meets most, together with spaces before the Arabic comma. Each of these is underlined where it happens, labelled spelling or grammar, with the standard form and the rule beside it.
Will it rewrite my Arabic?
Not unless you ask it to. A check corrects what is wrong and leaves your sentences as you wrote them; every change is a separate flag you accept or ignore. The Improve and Rewrite passes, which do change wording, are separate buttons, and the paraphraser is a separate tool.
Can I check a whole Arabic document?
Yes. Paste the text or drop in a .docx, .pdf or .txt file; the document is checked paragraph by paragraph and the corrected version can be copied or exported. Arabic runs right to left and the editor lays it out that way. Long documents are checked within the per-check allowance and continue as you scroll.
Is it useful if I am learning Arabic?
That is where the reason attached to each flag earns its keep. Nouns and adjectives agree in gender, number, case and definiteness (البيت الكبير, بيت كبير), with a dual form for two (بيتان) and the rule that non-human plurals take feminine singular agreement (الكتب مفيدة). A learner sees which rule was broken, not just the corrected word, and can accept the fix or read why it was raised before deciding.
After the check
Translate the corrected Arabic, change its tone, or shorten it. One plan covers every tool.
Each page opens the checker with that language already selected and explains what it looks for in it. The picker above the editor covers more than seventy languages in all.
