Nouns - Ουσιαστικά
Nouns in Greek are declinable words and may be classified as masculine, feminine or neuter. Although the determination of the grammatical gender of the Greek words is often arbitrary, the following rules may be applied with the necessary caution: Names of male persons and male animals are masculine. Names of female persons and female animals are feminine. Names of objects are usually neuter. However notice that in some cases names of persons and animals may be neuter as well and that names of visible and not-visible objects may also be either masculine or feminine.
