Hello friends! Today we'll learn about "Mein" (my) and "dein" (your) in German, which show possession. These words change based on the noun's gender. For "der" (masculine) and "das" (neuter) nouns, simply use "mein" and "dein" (e.g., mein Buch, dein Vater). However, for "die" (feminine) and plural nouns, add "-e" to get meine and deine (e.g., meine Mutter, deine Freunde). Knowing the noun's gender is crucial for correct usage. Practice makes perfect!
