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 zwavelzuur” rather than as “zwavelzuur” 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.
