die and dat
Duolingo says that "that is your chicken" should be translated "dat is jouw kip." But I thought that for "de" words, "that" = "die." ?
Apparently it's because "the independent demonstrative pronoun is linked to a noun by a link verb" as explained in the second half of the following page: http://www.dutchgrammar.com/en/?n=Pronouns.de03
In case you want to review everything on demonstrative pronouns you should start reading from: http://www.dutchgrammar.com/en/?n=Pronouns.De01
And that's right but it's in the case where that is a determinant. For example, "that chicken is good" would be "die kip is goed" because it's "de kip". However, in your case "that is you chicken", "that" is a pronoun not a determinant so it becomes dat.
