German/Possessive Pronouns

Personal Pronouns in the Nominative Case
A pronoun is a word that represents a noun, like "er" does for "der Mann." In the nominative case, the personal pronouns are simply the grammatical persons you already know: "ich," "du," "er/sie/es," "wir," "ihr," "sie," and "Sie."

Demonstrative Pronouns in the Nominative Case
The demonstrative pronouns in English are: this, that, these, and those. In German, the demonstrative pronouns in the nominative case are the same as the definite articles. That means, "der," "die" and "das" can also mean "that (one)" or "this (one)" depending on the gender of the respective noun, and "die" can mean "these" or "those." For example, if you talk about a certain dog, you could say "Der ist schwarz" (that one is black).
