This is the 1291st most frequent German word.
grosse
"Große" (or "groß") means "big," "large," or "great" in English.
Here, 'großen' correctly modifies 'Haus' (house), adjusted for case and gender in the sentence.
Anna wohnt in einem großen Haus.
Anna lives in a large house.
Here, 'große' is adjusted for gender and case to describe the size of the 'Tasse' (cup).
Ich habe eine große Tasse Kaffee.
I have a large cup of coffee.
In this case, 'große' reflects the masculine gender of 'Hund' (dog), indicating size.
