"The cow drinks water."
Translation:De koe drinkt water.
In Dutch words have gender and some animal words are neutral which require "het", while others are feminine or masculine which require "de", but lucky us, the plural takes "de" for all of them. The best thing to do is to memorize the words with their article. In German, there are three articles, one for each gender, so this is slightly easier.
