unserem

In a sentence

• Wir sollten unser Herz für unseren nächsten öffnen.

  We should open our heart to our neighbor.

  Here, "unserem" is the dative form of the possessive "unser" (our), and it aligns with the masculine "nächsten" (next, as in neighbor), signifying possession or association in a dative context.

• Mit unserem Wissen können wir anderen helfen.

  With our knowledge, we can help others.

  "Unserem" is used here in the dative case because of the preposition "mit" (with), which requires a dative noun. It modifies "Wissen" (knowledge).

• Wir verbringen viel Zeit in unserem Garten.

  We spend a lot of time in our garden.

  In this example, "unserem" is used because the preposition "in" (in) in this context governs the dative case, specifying possession of "Garten" (garden).
