Pronoungender is a placeholder-type gender for when one is non-binary and is unsure of what one's exact gender is, but one does know what their pronouns are.
In some cases, this may not be considered a placeholder, as some may think of their gender as nothing more than pronouns. It is a way of being non-specifically non-binary. [1]
Forms of pronoungender include, but are not limited to, shegender, hegender, itgender, and theygender.
