Why this article

No rule predicts it

This one has to be memorised. No spelling pattern marks it as neuter, which is exactly why it is worth learning as “het koolmonoxide” rather than as “koolmonoxide” on its own.

The rules that do work

  • Every plural takes “de”, without exception.
  • Every diminutive ending in -je takes “het”, without exception.
  • Nouns ending in -ing, -heid, -tie, -teit or -schap take “de”.
  • Roughly two thirds of all nouns take “de”, so it is the better guess.

Stop guessing de and het

Woordje has a practice mode for exactly this: it shows a noun and asks for the article, and keeps asking until you stop getting it wrong.
