Monumbo distinguishes five gender classes for singular and dual third-person pronouns, but only two gender classes (masculine and feminine) for third-person plural pronouns, a typologically unusual feature. There are five genders for the third-person pronoun, which are masculine, feminine, neutral, diminutive, and miscellaneous genders.[3]
