Demiboy
Demiboy names a gender identity that is partly male and partly something else, whatever the person was assigned at birth. The remainder can be another gender, several, or no gender at all, and the word says nothing about how large the masculine part is beyond it being less than the whole. Wiktionary takes the etymology no further than it needs to go: demi- plus boy, pronounced in three syllables, with the plural demiboys and an adjective sense alongside the noun. GenderGP's gloss for the same idea is man-adjacent, which carries the geometry of the term better than a fraction does: the position is next to a man.
What the record holds for Demiboy
First documented
2010
The AVEN user Bad Patient proposed demiguy, demidude and demibloke on 12 August 2010; the spelling demiboy followed and reached the Genderqueerid terminology page by 2011.
Coined by
Bad Patient, a user of the Asexual Visibility and Education Network forums, on 12 August 2010
How common
Established minority term
7.5 per cent of gender-diverse respondents in 2022
Demiguy, demiman, demimale and demidude are the same identity under other names, and people pick between them on how the word sounds, since nothing separates them in meaning. The counterpart is demigirl, which appears in the same sources under the further names demifemale and demiwoman, and the pair descends from a single forum post. Both sit inside Demigender, the general term for a partial connection to one gender alongside another gender or none.
Where demiboy was first written down
The record begins with a suggestion its author called half serious. In 2010 a user of the Asexual Visibility and Education Network posting as Bad Patient wrote that any word could be made to fit by putting demi- in front of it, and that having too much of a masculine element to call themselves Agender and feel good about it, they might be a demiguy, or a demidude, or a demibloke. INTO, which quotes the post, records that Bad Patient later said the suggestion had not been meant seriously, and that the word travelled regardless.
Two things follow from that post beyond the date. The first is that the coinage was reached by subtraction: the writer already had a word, agender, and wanted a weaker version of a different one. The second is that the list in the post is a list of synonyms, three at once, which is why the term arrived in circulation with four interchangeable forms and never settled on one.
Circulation followed quickly. By 2011 demiboy and demigirl had both been added to the Genderqueer Identities and Terminology page of the blog Genderqueerid, which is the first time either appears on a list somebody else maintained. INTO dates the settling of the definition now in use to Tumblr in 2014, four years after the forum post and one platform along.
Why the printed record for demiboy starts late
Wiktionary's citation file opens in 2015, five years after the forum post, with a piece by Kerri McNair in InfUSion, a University of Georgia publication, describing somebody who identifies as a genderqueer demiboy and uses ze and hir. Two further citations follow in 2017. One is from the anthology Come As Yourself, where the word appears in dialogue, a member of the family being introduced as a demiboy. The other is from L. Rowyn's novel The Sun Etherium, and it is the most useful of the three, because the character doing the describing draws a line: a demiboy blends neuter with male, as against a femboy, which the passage defines as a masculine shape with some feminine elements. A novel making that distinction in passing is evidence that the distinction was legible to readers by 2017.
INTO's roundup of demiboy characters and figures adds the later end of the same trail: Felix, the title character of Kacen Callender's young-adult novel Felix Ever After, Charley Condomine in the web series School Spirit, and Syle in the dating simulation The Office Type.
The person described is a genderqueer demiboy, with the newer word doing work inside a longer self-description, and the same stacking shows up across the popular coverage, where demiboy sits beside non-binary, Genderqueer or transgender.
No academic literature covers the word under this name, and Wiktionary is the only lexicon of record. That is a statement about what has been written down rather than about how many people use the word.
The counting sits elsewhere. The Gender Census carries demiboy as one of the identity words its respondents pick from, and its 2022 round drew 39,765 usable responses from a community-run, self-selected sample, which is the whole of what any share it reports is a share of. It also publishes what putting a word on the checkbox list does to it: the rise for demiboy was a factor of 6.4, against a mean of 10.1 across the words added that way.
How demiboy differs from a trans man
Queerty puts the difference in terms of completeness. A trans man's gender identity is male and stands in conflict with the sex he was assigned at birth; a demiboy holds part of a masculine identity, whichever assignment he started from. The two are not exclusive, and the Trans Youth Equality Foundation's terminology page, which Queerty cites, notes that transgender people may identify inside the binary, across it or outside it, so a person can be both Transgender and a demiboy. Queerty adds that gender dysphoria is not a prerequisite for being transgender, and demiboys, non-binary and genderqueer people may experience it as well.
The other side of the comparison is the part of the gender that is not male, and the sources decline to fix it. INTO describes demiboys as aligned with agender and with masculine genders without identifying equally with both; GenderGP puts the same point as a variable, saying the other part may be any gender, no gender, or a fluid one. Neither source names the remainder, and neither treats leaving it unnamed as a gap in the definition.
INTO gives the two cases that mark the range. One demiboy may be non-binary with a masculine presentation and expression. Another may have been assigned male at birth, feel no strong attachment to that assignment, and have no wish to move away from it entirely. The label covers both, which is what makes it useless as a prediction about anybody's presentation. Queerty says as much about clothes: some demiboys dress from the men's department, some dress androgynously, some mix the two, and none of it follows from the word.
Genderfluid is a different comparison again. A genderfluid gender changes, connecting with one gender and later another; a demiboy gender is stably partial, and the part that is not male does not have to move at all.
What demiboy looks like in other languages
Wiktionary's translation table is the closest thing the term has to a record of its spread, and it shows two different strategies. Some languages take the English word whole; others translate the parts, which is possible because demi- is a Latin-derived prefix several of them already own.
| Language | Form recorded | How the word was made |
|---|---|---|
| Catalan | deminoim | prefix on the native word |
| Esperanto | demiviro | prefix on the native word |
| French | demiboy, demi-garçon, demi-gars, demi-homme | the English word, and three native compounds beside it |
| Portuguese | demimenino | prefix on the native word |
| Russian | демибой | transliterated from English |
| Spanish | semichico, demichico | the native prefix, and the English one |
French is the informative row. It carries the English loan and three compounds of its own, which is what a term looks like partway through being naturalised rather than at either end of the process.
What the demiboy flag encodes
There is no official flag. The version in general use was made by the Tumblr user Transrants in 2015, and Queerty describes it as horizontal stripes in dark grey, light grey, light blue and white, which INTO counts as three colours across seven stripes. Transrants published no colour meanings. The readings in circulation come from the people flying it, and the two accounts agree: blue for masculinity, grey for the partial connection, white for agender and non-binary identities.
Pronouns follow no rule either. Queerty lists he and him, they and them, both used interchangeably by some people, and the neopronoun sets xe and xem, ze and zir, and ey and em. The 2015 citation from InfUSion is an early instance of exactly that: a demiboy using ze and hir, a decade before the article was written.
Told apart
Demiboy vs Transgender and Genderfluid
- TransgenderNot alternatives. A demiboy may or may not describe himself as transgender, and the terminology pages cited by the popular coverage say the choice belongs to the person.

- GenderfluidA genderfluid gender moves between genders. A demiboy gender stays partial without moving.

- DemigirlThe counterpart, coined in the same act. The only difference is which binary term the fraction is taken from.

- JuxeraJuxera and its near-male counterpart proxvir claim whole genders that sit beside the familiar ones. Demiboy claims part of the familiar one.

Common questions
Questions about Demiboy
- What does demiboy mean?
- Being partly a boy or a man and partly something else, whatever the person was assigned at birth. The other part may be another gender, several, or none at all.
- Where does the word demiboy come from?
- From a post made in 2010 by an Asexual Visibility and Education Network user calling themselves Bad Patient, who wrote that sticking demi- in front of a word made it fit and proposed demiguy, demidude and demibloke for a masculine element too strong to call agender. Bad Patient later said the suggestion had not been meant seriously. Demiboy and demigirl both descend from that post, and both had reached the Genderqueerid terminology page by 2011.
- Is a demiboy transgender?
- Sometimes, and it is the person's own call. The terminology page Queerty cites notes that transgender people may identify inside the binary, across it or outside it, so demiboy and transgender are compatible labels.
- What is the difference between demiboy and demiguy?
- Nothing but the word. Demiguy, demiman, demimale and demidude all name the same identity, and the choice between them runs on how the word sounds to the person using it.
- When does demiboy first appear in print?
- In 2015, in a piece by Kerri McNair in InfUSion, a University of Georgia publication, five years after the forum post that produced the word. Two more citations follow in 2017, both from fiction and personal writing.
- How is demiboy translated into other languages?
- Two ways, and Wiktionary records both. Some languages take the English word whole, as Russian does in transliteration and French does alongside its own forms. Others translate the parts, giving demi-garcon in French, demimenino in Portuguese, semichico in Spanish, demiviro in Esperanto and deminoim in Catalan.
