Overview
What aerogender means.
Aerogender is a xenogender in which a person's gender changes based on the setting or atmosphere they're in. That can mean something literal — temperature, weather, time of day, season, elevation — or something more metaphorical, such as comfort, mood, or who is in the room. Some people use it as a specific gender in its own right; others use it as an umbrella covering several related, atmosphere-linked genders.
What sets it apart from genderfluid is the proposed cause rather than the shape. Genderfluid describes gender moving on its own, for reasons that may never be traceable. Aerogender ties the movement to something outside the person — a place, a climate, an environment. In practice the two overlap heavily, and plenty of people who could reach for either word use genderfluid because it is far better known.
It is worth being upfront about how small this word is. It comes from a single wave of gender coinages made on Tumblr in the mid-2010s, and there is very little written about it beyond short wiki definitions. That does not make the underlying experience — feeling like a different gender depending on where you are — any less real, but it does mean there is no larger literature, community history or research to point to.
A gender that changes based on setting or atmosphere.

Origin
Where the word comes from
Aerogender was coined by the Tumblr user tenderagender, on or before 21 July 2014, as part of the broader mid-2010s trend of coining xenogender and mutogender terms on the site. The name comes from the Greek/Latin-derived prefix "aero-", meaning air, atmosphere, or aviation. Beyond that original post, little further history has been documented — no essays, interviews or later community discussion have surfaced.

Signs people describe
Common experiences
None of these is a test. Most people recognise a few and shrug at the rest.
You can usually name the cause of a shift — walking into your parents' house, sitting down at your desk, stepping outside in the cold — rather than just noticing you feel different for no reason.
The same body and the same day can read as fine in one room and unbearable in another, purely because the room changed.
Certain places reliably flip you: a particular building, a childhood bedroom, a specific kind of weather.
Asked "what's your gender today", your honest first thought is "where?"
You've picked a haircut or wardrobe that survives every environment, because none of them can be tailored per room.
You've noticed the shift happen mid-way through an ordinary day, with a doorway or a change of scene as the only trigger you can point to.
Being read wrong feels different depending on setting — a word that stings at work barely registers at home, or the reverse.
Pronouns
Pronouns
Aerogender says nothing about pronouns on its own. Many people settle on one set that can hold through every setting — they/them is common for this reason. Others ask for different pronouns in different places, which tends to work with individual friends and rarely scales to a whole workplace or family. A smaller number use ae/aer, an existing neopronoun set whose sound echoes the name. There is no single correct choice; what matters is picking something you can repeat on the days you have no energy to explain it.
Consider another path
This might not be your word if…
- 1What changes is only your behaviour or presentation from place to place, not your underlying sense of gender — that's code-switching, which most people do without it being a gender question.
- 2Your gender shifts, but you can never tie the shifts to any place, situation or atmosphere — genderfluid is likely the closer word.
- 3What actually varies is how safe you feel in a space, and going quiet or small there is fear doing its job, not gender doing anything.
- 4The changes track your mood, sleep, cycle or medication rather than your location or surroundings.

Related identities
Genderfluid
The much larger neighbouring term for gender that changes over time, with no requirement that a cause be identifiable. Most people who might use aerogender are understood immediately if they say genderfluid instead.
ReadGenderflux
Here the intensity of one gender rises and falls; the gender itself doesn't change. Aerogender is about which gender, not how strongly it's felt.

Xenogender
The umbrella aerogender sits under: genders described through something other than man, woman or a point between them — in this case, atmosphere and setting.
ReadAesthetigender
A neighbouring umbrella for genders anchored to a particular aesthetic or sensory quality; aerogender's atmosphere-based version sits close to this family.

Agender
If the honest answer in every room is blank rather than different, agender describes that better than a gender that moves.

Frequently asked questions
Is aerogender just genderfluid?+
They overlap a great deal. The distinction some people draw is cause: genderfluid shifts for reasons that may never be identifiable, while aerogender ties the shift to setting or atmosphere specifically. If that distinction doesn't matter to you, genderfluid is the far more widely understood word and costs nothing to use.
Is aerogender a real, documented identity?+
It was coined on Tumblr in 2014 and is used by a small number of people; there's no research, no wider community history, and only a couple of short wiki entries about it. That's a fair thing to know going in — the word is real in that people use it, but it isn't well documented.
What pronouns come with being aerogender?+
None specifically. Many people pick one durable set — often they/them — because it holds regardless of setting. Others use ae/aer or switch sets by context. The word describes what your gender is shaped by, not what to call you.
Is there an aerogender flag?+
A flag was posted to DeviantArt by the account Pride-Flags on 3 September 2015, but no confirmed meaning for its colours has ever been published, and at least one alternative design also circulates with an unknown origin.
The flag
A flag was posted by the DeviantArt account Pride-Flags on 3 September 2015, and an alternative design also circulates, but neither has a confirmed colour meaning or a settled status as 'the' aerogender flag, so no stripes are reproduced here.
