Gender is a highly important part of the grammar of many languages, and one must know a noun’s gender in order to use the correct form of its modifiers.
Masculine, feminine and neuter genders exist in English, but the designations are usually intrinsically obvious. For example, mother, sister, aunt and cow are feminine, while father, brother, uncle and bull are masculine. There are a few exceptions, and one may refer in English to a ship, a country or the moon as “she,” but it is more a matter of personification than rules of grammar. Hebrew differs from English in that there is only masculine and feminine gender. Grammatically, nothing can be an “it” in Hebrew, but always must be a “he” or a “she.”
