The rooms of a German home use the neuter article "das" because most end in the compound suffix "-zimmer" (room), which forces neuter gender. The kitchen is die Küche (a feminine exception), while the bathroom is das Bad or more formally das Badezimmer, the bedroom is das Schlafzimmer, the living room is das Wohnzimmer, and the dining room is das Esszimmer. Many of these compounds are formed by combining a verb with "Zimmer": "schlafen" (to sleep) gives Schlafzimmer, "wohnen" (to live) gives Wohnzimmer, and "essen" (to eat) gives Esszimmer. You might say "Ich koche in der Küche" (I cook in the kitchen) or "Das Bad ist neben dem Schlafzimmer" (The bathroom is next to the bedroom).
Clothing vocabulary covers the everyday items you need to dress for German weather. Common articles include das Hemd (shirt, plural die Hemden), die Hose (trousers or pants, plural die Hosen; note that "Hose" is singular in German even when referring to one pair), der Schuh (shoe, plural die Schuhe), das Kleid (dress, plural die Kleider), die Jacke (jacket, plural die Jacken), der Mantel (coat, plural die Mäntel), die Mütze (winter hat or cap, plural die Mützen), and die Socke (sock, plural die Socken). You can use these with color adjectives to make natural sentences, such as "Sie trägt ein rotes Kleid" (She wears a red dress) or "Im Winter trage ich einen Mantel" (In winter I wear a coat).
Animal words are an enjoyable category that often has surprising features. Common animals include der Hund (dog), die Katze (cat), der Vogel (bird, with the irregular plural die Vögel), der Fisch (fish, plural die Fische), das Pferd (horse, plural die Pferde), die Kuh (cow, plural die Kühe), das Schwein (pig, plural die Schweine, also used in the cheerful expression "Viel Schwein!" meaning good luck), and die Maus (mouse, with the irregular plural die Mäuse). Animal names follow all three grammatical genders, and the umlaut in plural forms (Vögel, Kühe, Mäuse) is a useful pattern to recognize. Together, these vocabulary categories of home, clothing, and animals equip you to discuss your daily life, your surroundings, and even the natural world in German.
