In Dutch, nouns come in three genders: masculine, feminine and neuter. The gender of a word determines the articles used with it and the pronouns referring to it. Sometimes masculine and feminine nouns are collectively called de-words, whereas neuter nouns are called het-words, in accordance with the definite article used with them. Traditionally, pronouns used for masculine nouns are hij/hem/zijn, feminine zij/haar, neuter het/zijn. In some parts of the Netherlands, awareness of the distinction between masculine and feminine nouns is disappearing, and using the masculine pronouns for feminine nouns has become quite common in speech and accepted in informal writing. In Belgium the distinction is usually, but not always, maintained. For a large number of words no clear division is determined, and dictionaries just indicate them as de-words. It has been suggested that natural gender be merged into this article or section. ... The word neuter can refer to: the property of being neither biologically male or female: being asexual the sterilization (castration, spaying, etc. ...
