"I hope that I will see you again."
Translation:Ik hoop dat ik je weer zie.
De and het are classified as definite articles. De is always used for plural words-de herten (the deers). Het is always singular-het hert (the deer). Beware, though! Not every singular word is a het word. Example: De boek (the book). There are suffixes that indicate whether a word requires de or het; however, it is largely a matter of memorization.
