DE or HET ?
In English, the definite article has only one form: the. But Dutch has two forms: de and het.
In general, you have to learn the article together with the noun, but there are some rules:
all words that end in -JE
all colours, languages and fabrics
all plural words
all numbers, letters, mountains, oceans and rivers
most persons, animals, flowers and musical instruments
The rest is just because....When you're in doubt, choose DE.
