Gender in Esperanto: -in-, ge-, and the Reform That Waits

By Michael McGettrickUpdated 12 October 2026

has no grammatical gender: one article, no agreement, and most nouns are neutral. What it has is a short list of male roots, the suffix -- to make the female, and the prefix - for both sexes together. Around that sits a live about ri and -iĉ-.

No grammatical gender

There are no masculine and feminine nouns, and adjectives do not change for sex. The article is always :

  • - the good doctor (of any sex)
  • - the good girl
  • - the big house

A French or German learner spends years on noun gender. An Esperanto learner spends an afternoon on a word list, and -- never spreads to the rest of the sentence: , never a.

Neutral roots and male roots

Most roots are sex-neutral. PMEG says the neutral group is , without doubt the largest. It holds , and , and the profession nouns.

Four people in their work clothes: a woman doctor with long hair and a bow, in a white coat with a stethoscope; a man teacher with glasses, a moustache and a tie, pointing at a board and holding a book; a man cook with a moustache, in a chef's hat and apron, holding a frying pan with an egg; a man police officer with a moustache, in a blue uniform and cap.

A doctor (here a woman), a teacher and a cook (here men): kuracisto, instruisto, kuiristo. Profession nouns say nothing about sex.

  • . - She is a doctor.
  • . - He is a doctor.

A short list of roots is male. PMEG calls this group much smaller and , more closed, and ends each group with k.a., and others:

GroupMale roots
General, , , , , masklo
Family, , , , , ,
Family, , , vidvo
Titles, , , , ,
on
Animalstaŭro, and a few more male-animal roots

The trap is assuming the list is longer: and are not on it. A handful of roots are female in themselves (, a lady), and they take no --.

-in- and vir-

-in- (female)vir- (male)What do the colours mean?

-- makes the female of a male root. One suffix, no exceptions, no change to the root:

patro, father; patrino, mother
MaleFemaleEnglish
father, mother
brother, sister
king, queen
Mr, Mrs
boy, girl
A friendly family tree drawn on a big green tree: the grandmother and grandfather at the top; below them their son (the father) with the mother beside him, and the father's brother (the uncle); at the bottom, the parents' two children, a smiling girl with a sparkle and her younger brother.

avino, avo: grandmother, grandfather; patrino, patro: mother, father; onklo: uncle; fratino, frato: sister, brother.

-- can also specify the female of a neutral root. PMEG calls this optional, though traditionally speakers add it routinely when they mean a woman or a female animal:

  • - a cow (, a bovine of either sex)
  • - a female dog
  • - a woman doctor (correct, and says more than )

Going the other way, the root - in front marks a male:

  • - a bull
  • - a male dog

-- is also a word, as most affixes are: is a female, is female as an adjective.

Ge-: both sexes together

ge- (both sexes)What do the colours mean?

- means both sexes. Traditionally the word it makes is plural, and these plurals are everyday words:

WordEnglish
parents (mother + father)
brothers and sisters
sons and daughters
a married couple
ladies and gentlemen
  • Parizo. - My parents live in .
  • oj! - Ladies and gentlemen!

- also goes on neutral roots when you want to stress that both sexes are there: oj, pupils of both sexes. Normally plain does the job. PMEG advises against the singular o and o, since and are neutral already.

The newer use is the singular. PMEG states the tradition, that a - word with -o can only be plural, then records an experimental singular meaning any sex that has grown over the last few decades:

  • . - Every parent wants to help.

PMEG also names the cost. If - can mean any sex, then can mean a decision by one parent rather than by both. Both readings are in use; the plural one is understood by everyone.

The criticism, both ways

The argument is a century old because both sides have a point:

PointFor changeThe reply
Marking is plus morethe male list is short and closed
Male suffixnone: does both jobs-- is one regular suffix
Pronouns or states a sex, , are neutral

Traditionally covers a person of unknown sex. PMEG notes that this can be seen as discrimination and offers , or instead:

  • , . - If anyone wants to come, they can come.

Ri, -iĉ- and the other proposals

-iĉ- (male)-in- (female)What do the colours mean?

Riismo usually means using ri; the word also covers wider programmes. None of these forms is official, and some speakers use them every day:

ProposalWhat it doesStanding
rihe or she: one person, any sexthe most used; unofficial
kuracistiĉoa male suffix to mirror --used by some; unofficial
ŝlia blend of and a rival; less used than ri
for peoplethe pronoun for thingsa few use it; it can sound objectifying

People use ri in three ways: for a person whose sex is unknown, only for non-binary people, or for everyone instead of and . PMEG says riismo is , , fairly widespread, especially among young people, and that some strongly oppose it as an unacceptable .

  • , ri . - My friend said that they would come.

-Iĉ- is modelled on --, the male pet-name suffix, just as -- pairs with --. Its main use is on neutral roots, where it does the job of -: kuracistiĉo, a male doctor; boviĉo, a bull. PMEG calls it by far the most popular proposal of its kind, though most speakers still use or -. Some go further and put it on the male roots too, so that would mean parent and patriĉo father. PMEG calls that a real of common, deep-rooted words, and so hard to achieve.

What the Akademio said

  1. 1976earliest known proposal of ri, in print

  2. 2021the Akademio declines to decide

  3. 2031earliest return to the question

In March 2021 the Esperanto published this declaration:

Esperanto , uzindeco - ( ri ŝli), i .

The Esperanto declares that it does not at present take a position on the usability of unofficial sex-neutral pronouns (such as ri or ŝli), and has decided not to take up the subject for at least ten years.

That is neither approval nor a ban. It is how the language usually changes: usage first, ratification afterwards, if at all. The Fundamento and Akademio article explains why.

  1. Use -- where tradition puts it: , , .

  3. Leave profession nouns bare unless sex is your point: .
  4. Reach for and when sex is beside the point.
  5. Recognise ri and -iĉ-, and use the pronoun a person asks you to use.

Words about sexuality

Ordinary dictionary words, given here once because learner material rarely does:

WordEnglish
sex (male, female)
a gay man
gay
attracted to the same sex
heterosexual
bisexual

Both families are in everyday use: and are short and informal, and is the plain descriptive word.

Mistakes English speakers make

WrongRightWhy
a adjectives do not agree for sex
o-- is already there
. . takes the male form
ojoj- already includes the women

What to do next

  1. Write five family words with -- and five with -.
  2. Describe three people by profession with no --.
  3. Then read affixes for size and people for --, -- and --.

Frequently asked questions

Does Esperanto have grammatical gender?
No. Nouns have no gender class, adjectives do not agree for sex, and there is one article, , for everything: is a good doctor of any sex. What Esperanto has is a fact about a short list of roots that mean a male person or animal. That is vocabulary, not grammar.
Which Esperanto words are inherently male?
A small, fairly closed set. PMEG groups them: general words (, , , ), family words (, , , , , , , , , ), titles (, , , , ) and a few religious and animal roots (, taŭro), each group ending with and others. Almost everything else, including the profession nouns, is neutral.
What is the difference between and ?
Number, and a change in usage. Ge- means both sexes, so traditionally a ge- word is plural: is a mother and a father. For some decades people have also used the singular, , for one parent of any sex. PMEG records this as an experimental use that has grown, and notes that it shifts the meaning of older words such as .
Is ri an official Esperanto word?
No. Ri is an unofficial pronoun for one person of any sex. Some use it only when the sex is unknown, some only for non-binary people, and some instead of and altogether. In March 2021 the Esperanto declared that it takes no position on such pronouns and will not take up the subject for at least ten years.
What should a learner write today?
The forms every reader knows: -in- where tradition puts it (, ), ge- for a mixed group (), profession nouns without -in- unless sex matters ( ), and or when sex is beside the point. Recognise ri and -iĉ- when you meet them, and use the pronoun a person asks you to use.
