8 Gender of NounsAll nouns in Spanish have gender, that is they are designated either masculine or feminine. The gender of a noun has nothing to do with what the noun is or who uses it. The only exception to this is words that represent a male (man, boy, father, etc.) are masculine and words that represent a female (girl, woman, mother, etc.) are feminine.
9 Gender of NounsUsually, masculine nouns end with –o and feminine nouns end with –a. There are many exceptions to this rule, but for the majority of nouns this works. The only way to tell for sure if a noun is masculine or feminine is to look at the article that precedes it. If it has un, unos, el or los, it is masculine. If it has una, unas, la or las, it is feminine.
