Spaced repetition is the most evidence-backed method for vocabulary retention. Instead of reviewing words randomly, spaced repetition software (SRS) calculates the optimal moment to show you each word — just as you are about to forget it. This exploits the spacing effect: memories grow stronger when recalled across increasing intervals. Apps like Anki (free, highly customizable) and Duolingo (gamified, lower customization) implement SRS algorithms automatically.
For Dutch specifically, download a pre-made Anki deck (search “Dutch frequency list” or “Dutch 5000 most common words”) or build your own from words you encounter in reading and listening. The ideal card format: Dutch word on the front, English translation + example sentence + audio pronunciation on the back. Audio is important — you want to connect the sound to the meaning, not just the spelling.
Consistency beats intensity: 15 minutes of Anki every day outperforms 2-hour sessions twice a week. The SRS algorithm loses its power if you skip days, because cards pile up and the optimal timing is disrupted. Set a manageable daily new-card limit (10–15 new cards per day for beginners) and honor it. After 6 months of consistent Anki use, most learners report noticing the same words appearing naturally in Dutch media — the moment when passive recognition becomes active recall.
