Polyfluid

Several genders, and fluid between them: often more than one at a time, and which ones keeps changing.

A shorter entry: the essentials, written to the same standard. The fuller guides are on the main identities.

What it is

Two words stacked. Polygender: several genders. Genderfluid: it moves. Polyfluid is fluid between combinations of several genders. Man and something unnamed on Monday, woman alone on Wednesday, three things at once by the weekend. The record on the wiki says it plainly: often multiple genders at once, though not necessarily all the time.

The difference from plain genderfluid is the arithmetic. A genderfluid person usually lands on one thing at a time. Polyfluid lands on sets. The difference from plain polygender is the motion: polygender can hold its several genders steadily for years. Polyfluid's set keeps being reshuffled.

What it is not: it isn't 'fluid, but a lot'. It's a specific shape, and a very small word. The wiki dates it to 2020, and there is nothing written about living with it beyond the definition. Many people who fit it say 'genderfluid' in public and 'polygender and fluid' when it matters. That's fine. The combined word is a convenience, not a requirement.

Pronouns

No pronoun comes with this. Most people keep one public set, often they/them, because it holds across every combination, and tell a few people that the inside moves. Some switch with the shift. Some list two or three and let people pick. If you speak a gendered language, this was never a pronoun question; it's a whole-sentence question, and you're doing more work than the word suggests.

Does this sound like you?

The answer to 'what's your gender today' is a list, and the list was different last week.
You might have tried genderfluid and found it kept asking which one, when the honest answer was usually two or three.
Polygender described the count, but not the reshuffling.
You might feel two of your genders arrive together, argue, and settle into something that isn't either of them by evening.
You keep a note of combinations rather than genders, because the combinations are what recur.
You might have days that are simple, one gender, whole, all day, and find those days almost unsettling for how quiet they are.

Nearby identities

The distinction is the useful part.

Polygender

Several genders, held. Polygender says how many; it doesn't require movement. If your set is stable, the same three, always, polygender is the word, and the better-documented one.

Compare Polyfluid and Polygender →
Genderfluid

Movement between genders, usually one at a time. Polyfluid adds that you often hold more than one at once, and that the combination is what moves.

Compare Polyfluid and Genderfluid →
Multigender

The umbrella for having more than one gender, however many and however it moves. Polyfluid sits under it, as does polygender.

Compare Polyfluid and Multigender →
Fluidflux

Which gender and how much of it, both moving. Polyfluid is about which combination. Some people have all three dials, and both words apply.

Compare Polyfluid and Fluidflux →
Bigender

Exactly two, both whole, sometimes alternating and sometimes stacked. If the count is always two, bigender describes it and has far more company.

It might not be you if…

  • You land on one gender at a time, always. That's genderfluid, and the polygender half is doing nothing for you.
  • Your several genders are stable, the same set for years. That's polygender, and the fluid half is doing nothing for you.
  • It's always the same two. Read bigender before this.
  • Everything feels like many things at once because you started asking six weeks ago. Early on, everything wobbles. Give it a season before you build machinery with two moving parts.

Questions people ask

What's the difference between polyfluid and genderfluid?

Count. Genderfluid usually moves between single genders. Polyfluid moves between combinations, and often holds more than one at a time. If 'which gender are you today' has a one-word answer most days, genderfluid is the word.

Is polyfluid the same as multigender?

Multigender is the umbrella: more than one gender, in any arrangement. Polyfluid is one arrangement under it, several genders, fluid between combinations of them. You can honestly use both.

Is this a real identity or just two words glued together?

Both. It came out of online spaces recently and there's very little written about living as it. The experience it points at, several genders in shifting combinations, is real for the people who describe it, and the glued word is simply the fastest way to say it. If two older words do the job for you, use those.
