The word "family" is spelled "la famiglia" in the Italian language. All nouns in Italian have a gender and are either masculine or feminine. Nouns ending in an "a" are typically feminine and are thus preceded by "la."
Masculine nouns usually end in an "o" and are preceded by "il" rather than "la." Gender is assigned to nouns regardless of whether it refers to a person or to a place, thing or idea. A family can consist of a mixture of males and females, but the concept of family in the Italian language is always feminine. Individuals of both genders refer to their own family with the phrase "la mia famiglia."
