The Portuguese language as a rule determines that the plural of nouns, when covering individuals of the feminine and masculine gender, is made based on the generic masculine: a collective of "vinte meninas" ("twenty girls") and "dez meninos" ("ten boys"), is said as "trinta meninos" (literally, "thirty boys"). This form of plural formation is considered sexist by certain groups and individuals, resulting in proposals for a neutral gender to be adopted, such as "thirty children" ("trinta menines").
