In Greek every noun and pronoun is assigned a specific gender. Even nouns that do not refer to humans may be masculine or feminine. For example, ἄρτος (the Greek word for “bread”) is masculine, even though the object to which it refers is neither male nor female.

Similarly, some words that do refer to humans are assigned neuter gender. For example παιδίον (a Greek word for “child”) is neuter, even though any given child is either male or female. The word κοράσιον (“girl”) is neuter even though it always refers to a female. Gender in Greek is a matter of grammar, not biological sex, even though most words that refer exclusively to males are assigned masculine gender and most words referring exclusively to females are assigned feminine gender.
