Turkish grammar checked with the reason attached
Paste Turkish and every issue is underlined where it happens, labelled spelling, grammar, punctuation or style, with the reason attached. Turkish is written in the Latin alphabet, and vowel harmony, the dotted and dotless i, the suffix chain, de/da 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 Turkish grammar
Three steps. The third is the one most checkers leave out.
1
Paste or upload the Turkish
Type, paste or drop in a document. Turkish is already selected as the language on this page. 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. Turkish 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 Turkish
The parts of Turkish grammar and spelling where a checker has to know the language, not just the words.
AgreementTurkish has no gender and no articles; meaning is built by suffixes that obey vowel harmony (evler, kitaplar; evde, kitapta) and consonant assimilation. The order of suffixes (plural, possessive, case: evlerimizde) is fixed, and a wrong vowel in one of them is the visible error.
VerbsVerbs take tense, person and mood as suffixes, and the subject is dropped. The -yor present against the -r aorist (geliyorum, gelirim) and the reported past -miş against the witnessed past -di are the choices that carry meaning; the verb sits last in the sentence.
Spelling and diacriticsThe dotted i (İ, i) and the dotless ı (I, ı) are different letters, as are ç, ğ, ö, ş and ü. Text written without them (Istanbul for İstanbul, sisman for şişman) is a spelling error, and the capital of i is İ, not I.
PunctuationThe apostrophe separates a suffix from a proper noun (Ankara’da, Ayşe’nin) and is not used with common nouns. Decimals take a comma. A comma follows a sentence-opening subject only when needed to avoid misreading.
Capital lettersDays and months are lower case except in dates; languages and nationalities are capitalised (Türkçe, Türk). Titles before a name are capitalised (Doktor Ayşe).
Common mistakes in Turkish writing
Five errors Turkish readers notice at once, and what the checker does with each.
de/da written together or apart
Evde (at home) is one word; ben de (me too) is two. The locative suffix joins the noun; the conjunction stands alone and never becomes te/ta.
Dotted i, dotless ı
Ilık (warm) and ılık are the same word only once the dot is right; İstanbul, İzmir take the capital İ. On a keyboard without Turkish letters this is the first thing to check.
Broken vowel harmony
Kitaplar, not kitapler; evlerde, not evlerda. Every suffix takes the vowel class of the stem, and the checker underlines the suffix, not the stem.
The apostrophe with proper nouns
Türkiye’de, Ali’nin, but okulda and arkadaşımın. Only proper nouns take the apostrophe before a suffix.
ki joined or separate
Benimki, seninki (possessive, joined) against biliyorum ki (conjunction, separate). Sanki, halbuki, çünkü are single words.
Formal and informal Turkish
Sen and siz: siz takes the plural verb ending (siz geliyorsunuz) and is the standard for strangers, customers and elders. The plural of respect is grammatical, so a text that mixes sen and siz forms is wrong, not just informal.
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 Turkish here
1
Students in Turkey preparing for the YKS and university essays, where de/da is a marked error.
2
Turks abroad writing on keyboards without ı, ş and ğ.
3
Businesses writing to Turkish customers, where siz and the apostrophe rule are read as care.
Turkish grammar checker FAQs
Is the Turkish grammar checker free?
Yes. Check Turkish 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 Turkish does it check?
Standard written Turkish, spelled as the current standard has it. The best-known Turkish spelling question is the suffix -de/-da (locative, written together: evde) against the conjunction de/da (also, written apart: ben de). Turkish is preselected on this page; the language menu above the editor changes it if the text turns out to be something else.
Does it correct Turkish spelling as well as grammar?
Yes, and in Turkish the two overlap. The best-known Turkish spelling question is the suffix -de/-da (locative, written together: evde) against the conjunction de/da (also, written apart: ben de). Ki as a suffix (benimki) is joined, ki as a conjunction is separate. The TDK spelling guide is the standard. 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 Turkish?
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 Turkish 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. Long documents are checked within the per-check allowance and continue as you scroll.
Is it useful if I am learning Turkish?
That is where the reason attached to each flag earns its keep. Turkish has no gender and no articles; meaning is built by suffixes that obey vowel harmony (evler, kitaplar; evde, kitapta) and consonant assimilation. 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 Turkish, 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.
