🇳🇱 Best Dutch websites for advanced learners

A long-running independent reference covering spelling and pronunciation, verbs, pronouns, nouns and articles, and the word-order rules that trip up every English speaker — with sound files and exercises attached to the explanations. When you need the actual rule rather than a video's summary of it, this is where to look. Free and ad-light, with a forum where questions still get answered. The site design is firmly from an earlier era of the web.

A collaborative, Creative Commons-licensed corpus you can search for real usage of a word or download in bulk to build your own decks. It is the raw material behind Clozemaster and countless Anki decks rather than a study tool in itself. Sentences are contributed by volunteers, so quality and naturalness vary — prefer sentences from native contributors and cross-check anything surprising.

Over 100 language editions; the English edition alone has millions of entries covering hundreds of languages, with IPA, declension and conjugation tables, etymologies and usage notes that commercial apps usually paywall. The etymology sections are quietly one of the best vocabulary-retention tools available. Being crowd-sourced, coverage is uneven and rare entries can be wrong — cross-check anything unusual against a native-language dictionary.

The Taalunie's official word list, the online edition of the Groene Boekje, giving the sanctioned spelling, plural, diminutive and verb forms for well over a hundred thousand words. This is the arbiter when you cannot decide whether a compound takes a hyphen or how a borrowed verb conjugates. Free, and shared as the standard for both the Netherlands and Flanders. It settles spelling only — it gives no definitions, so pair it with a real dictionary.

Type a word or phrase and it plays back real YouTube clips of people saying it in context, across 25 languages plus sign languages, so you get natural intonation and regional variation rather than an isolated dictionary recording. Free, donation-supported, no account needed. Complements Forvo: Forvo for single words, YouGlish for phrases and prosody.

A browser extension plus web reader covering 100+ languages: click a word or drag across a phrase, get an inline translation, and it becomes a flashcard automatically. The free tier gives unlimited single-word translations but caps phrases and AI explanations at 10 a day; Premium is $6/month. Simpler and cheaper than LingQ or Migaku if all you want is frictionless reading of articles and ebooks.

A detailed staged roadmap for acquiring a language through massive comprehensible input — what to do at each stage, when to start output, how to mine sentences — with a free tracker, starter courses and an active Discord. The roadmap and community are free; vocabulary decks, advanced courses and coaching are paid. It is opinionated to the point of dogma about avoiding early output and translation, so take the framework and ignore the purity rules if they do not fit your goals.
