Grammar
De / Het Articles
Every Dutch noun is either a de-word (common gender) or a het-word (neuter gender). There are no rules that cover every case, but a solid set of patterns will get you most of the way there — and when in doubt, de is the safer bet.
de man · de vrouw · de fiets — common gender (roughly ⅔ of all nouns)
het huis · het boek · het kind — neuter gender (roughly ⅓ of all nouns)
All plural nouns always use de, regardless of the singular article.
1. When it is het
These patterns reliably predict het. If a noun matches one, it is almost certainly neuter.
2. When it is de
These patterns reliably predict de. The most useful ones are the noun endings.
3. Compound nouns
Dutch loves to combine words into one long compound. The article is always determined by the last word of the compound.
4. Plurals are always de
No matter what article a noun has in the singular, its plural always takes de.
5. Practical tips
Don't memorise "huis" — memorise "het huis". Treat the article as part of the word from day one.
About two-thirds of Dutch nouns are de-words. If you're unsure, de is statistically the better bet.
Van Dale and Woorden.org list the article for every noun. When you look up a word, always note the article too.
If you know the diminutive form, you know the het-word rule is at work — and you know the noun's stem.
In attributive position, het-words use a bare adjective before the indefinite article: een groot huis (not een grote huis). De-words always take -e: een grote auto. This can help you identify a word's gender in context.
