Diesen

Diesen is a German demonstrative pronoun and adjective. It translates to "this" or "these" in English, and it is used to refer to something near in time, place, or thought. The form of diesen changes depending on the gender, number, and case of the noun it modifies or replaces.

Diesen is used as the masculine accusative singular, feminine dative singular, and plural dative form.

Declension:

The declension of dieser (of which diesen is a form) follows a similar pattern to the definite article der. Here's a simplified table showing the relevant cases for diesen:

• Masculine Accusative Singular: diesen Mann (this man)
• Feminine Dative Singular: mit dieser Frau (with this woman - diesen would not be used directly before the noun in this case, but rather as part of the declension of dieser)
• Plural Dative (all genders): mit diesen Kindern (with these children)

Usage Notes:

• Diesen is used to point out a specific item or items from a group.
• It implies a closer relationship or proximity than pronouns like jener ("that" / "those").
• The correct form of dieser must be chosen based on the grammatical context.
