In Icelandic we have the neopronoun “hán”, which I know some nonbinary folk here use regularly. I’m not a native speaker so I can’t properly evaluate how awkward it is, and I’ve definitely seen grumbling from natives about how it doesn’t feel natural, but to me as a learner it feels completely reasonable and fits into the rather complicated grammar of Icelandic perfectly.

Just like how English distinguishes between subject/object/possessive for pronouns (I/me/my, he/him/his, she/her/her, they/them/their), Icelandic has 4 cases for nouns and pronouns. Hán behaves exactly like a regular neuter noun when inflected, declining like “hán/hán/háni/háns” for each of Icelandic cases. Compare the regular neuter word borð (table), which declines like “borð/borð/borði/borðs”.

Adjectives also decline for gender in Icelandic, but as you may have guessed nonbinary folk predominantly use the neuter gender, which agrees with the pronoun hán. There of course already existing a third person neuter pronoun in Icelandic, “það”, but its meaning is more like the English “it” and most people prefer understandably to not to go by it.

Also interesting but not pronouns is how Icelanders use names. Basically Icelanders don’t have a family name the way most other western countries do (… with exceptions), their last name is instead the name of their father, in possessive, plus -son or -dóttir. So if you are the son of your father, Einar, your last name would be Einarsson, literally “Einar’s son”. If you were the daughter of Einar, your last name would be Einarsdóttir, literally “Einar’s daughter”. This system of surnames is called patronymic surnames, and recently there has been more matronymic surnames as well – for example former football player Heiðar Helguson’s mother would have been called Helga, and his last name means “Helga’s son”.

This is of course problematic for nonbinary people who do not wish to use either -son or -dóttir, but recently it was allowed to use the neuter ending -bur instead, which repurposes an archaic word meaning “son” but is just used to mean a gender neutral “child” nowadays.

It’s complicated in German. Almost every noun being gendered brings up a bunch of issues unknown to the English speaking world, long before we get to the topic of non-binary folks.

Just imagine every job description, occupation and whatnot being gendered, with male being the default. In English this is rare nowadays, in German it’s baked into the language. A doctor and a doctoress, a maypr and a mayoress, a student and a studentess, a cyclist and a cyclistess.

The feminist movement has been trying to find solutions for this for decades, they are fairly controversial among older conservative folks, and admittedly inelegant.

Concerning non-binary folks it gets even more complicated. Not only does referring to almost any description automatically infer a binary gender, we also don’t have any option for unspecified pronouns other than “it”, which is hugely dehumanizing. The equivalent of “they” is already used as a honorific.

Some people tried introducing neopronouns but they never took off. Most enbies I know simply chose the binary pronoun they are the least uncomfortable with and stick with that.

Adding the Portuguese experience, I’ve seen the more inclusive communities within Portugal replaces the “o” and “a” vowels in gendered words with “e”, i.e. todos/todas becomes todes, amigos/amigas becomes amigues, etc.

For pronouns, there’s currently 3 sets of different gender-neutral pronouns I’ve seen used or in circulation. One is to drop the gendered vowel that terminates the pronoun, i.e. ele/ela becomes el, dele/dela becomes del. This still does have some ambiguity, so I’ve seen a greater adoption of pronouns that I’ve heard come from Latin roots. The two variants I’ve seen more often adopted are ele/ela → elu and ele/ela → ilu.

These gender-neutral pronouns are still not widely used outside inclusive communities, but I’ve heard of individual cases of wider adoption. I think I’ve heard of a book that was printed by a major publisher that for the first time used gender-neutral pronouns in its translation, and you start seeing some places use these pronouns in place of gendered pronouns in signs.

In more traditional media it’s still not common, but if they need to, what they tend to use is gender avoidant language, that explicitly avoids using pronouns or gendered names, for example, to replace ele/ela with “esta pessoa”, as “pessoa” is one of a few nouns that can be used that does not imply gender. But it isn’t easy to avoid gendered words and pronouns for a long period of time, and what I’ve heard from a few translator friends is that this is a complex and tiresome process as each sentence needs to be very carefully constructed, instead of the much easier process of the newer but still not widely adopted gender-neutral pronouns.
