Dutch grammar checked with the reason attached

Paste Dutch and every issue is underlined where it happens, labelled spelling, grammar, punctuation or style, with the reason attached. Dutch is written in the Latin alphabet, and the -d / -t / -dt endings, compounds written as one word, de and het 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 Dutch grammar

Three steps. The third is the one most checkers leave out.

1

Paste or upload the Dutch

Type, paste or drop in a document. Dutch 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. Dutch 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 Dutch

The parts of Dutch grammar and spelling where a checker has to know the language, not just the words.

  • AgreementNouns are de-words or het-words, and the adjective ending follows: een groot huis but het grote huis, de grote man. Choosing the wrong article is the error every learner makes and the one native writers almost never make.
  • VerbsThe verb goes second in a main clause and last in a subordinate clause. The spelling of the present tense and the past participle follows the ’t kofschip rule, and the -d, -t and -dt endings that sound alike are the country’s best-known spelling problem (hij wordt, ik word, hij heeft gewerkt).
  • Spelling and diacriticsDutch uses the diaeresis to separate vowels that would otherwise merge (ideeën, ruïne, geïnteresseerd) and the acute for emphasis or in loanwords (één, café). The tussen-n in compounds (pannenkoek) follows the official rules.
  • PunctuationStandard; a comma is not required before dat or omdat, unlike German. Decimals take a comma.
  • Capital lettersDays and months are lower case; languages and nationalities are capitalised (Nederlands, een Nederlander). The formal U may be capitalised in letters but usually is not.

Common mistakes in Dutch writing

Five errors Dutch readers notice at once, and what the checker does with each.

-d, -t or -dt

Ik word, jij wordt, hij wordt, word jij? The stem plus t for the second and third person, stem alone for ik and in the inverted question. Sounds identical; grammar decides, and this is the single most searched Dutch spelling question.

Compounds split into two words

Dutch writes a compound as one word. Klantenservice, not klanten service; softwareontwikkelaar, not software ontwikkelaar. A hyphen is allowed only where the parts would otherwise be misread.

De or het

Het meisje, het boek, de tafel: there is no rule that covers every noun, and the adjective ending depends on the choice (een mooi meisje, een mooie tafel).

Als and dan in comparisons

Groter dan (bigger than) but even groot als (as big as). Groter als is heard everywhere and marked as an error everywhere.

Hen, hun and zij

Hun is possessive or indirect object (hun huis, ik geef hun); hen is the direct object (ik zie hen); zij is the subject. Hun as a subject (hun hebben) is a marked error in writing.

Formal and informal Dutch

Je/jij against u: u takes the same verb form as the third person in most cases (u heeft or u hebt are both accepted) and is expected with strangers, customers and older people, more so in Flanders. Mixing them inside one message reads as careless.

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 Dutch here

1

Pupils and students in the Netherlands and Flanders, where the dt-error still costs marks.

2

Companies writing to Dutch and Belgian customers in a language they read but do not write daily.

3

Learners at the inburgering and NT2 levels who want the reason for each correction.

Dutch grammar checker FAQs

Is the Dutch grammar checker free?

Yes. Check Dutch 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 Dutch does it check?

Standard Dutch as used in the Netherlands and Flanders, spelled by the official Woordenlijst (the Green Booklet). Flemish usage differs mainly in vocabulary and in the wider use of the formal u. Dutch is preselected on this page; change the language menu above the editor if the text is a different variant.

Does it correct Dutch spelling as well as grammar?

Yes, and in Dutch the two overlap. Compounds are written as one word (langetermijnplanning, klantenservice), and splitting them under English influence (lange termijn planning) is the modern Dutch error. The 2005 spelling is the standard, including the tussen-n and the treatment of English loanwords. 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 Dutch?

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 Dutch 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 Dutch?

That is where the reason attached to each flag earns its keep. Nouns are de-words or het-words, and the adjective ending follows: een groot huis but het grote huis, de grote man. 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 Dutch, change its tone, or shorten it. One plan covers every tool.
