Dellogender — Having at least one allogender, and at least one demigender. In other words, experiencing certain genders fully, while experiencing other genders only partially.
The term was made with the “between one and two genders” experience in mind, but anyone with both at least one allogender and at least one demigender can use it, even if it totals two or more.
Etymology, flag symbolism, and further info is below the cut.
Etymology — A portmanteau of the demi- and allo- prefixes; inspired by the dellosexual label.
Flag Symbolism — The flag is divided into sections.
The grey side represents the demigender part of the identity. It is half the size of the purple side, visually representing how the demigender side takes up "less gender space" than the allogender side. Both shades of grey were taken directly from the demigender flag.
The purple side represents the allogender part of the identity. It is inverted from the agender flag's green.
The white stripes work together to create half a plus sign, representing the addition of multiple genders, at least one of which is only partial.
