díuinin is the mazadmáh practice of taboo gender non-compliance in which a person with a masculine body by birth takes on a feminine social role and appearance, often through assistance of duním, a regional herb drunk as a tea for its feminizing properties.

a person who performs díu̯inin by taking on that gender role is known as a díuinis (collective ihdíuinis) and can be described through the verb díuin “she feminizes herself, is a díuinis”.


all of these terms derive from the mazadmáh root d·u·n which originally described only breasts or the process of breastfeeding but had many derivatives generalizing the root to instead describe femininity or womanhood in mazadmáh society.
