Esperanto speakers have proposed changes since the language's early years. Some proposals remain experiments, some innovations enter ordinary usage without altering the core, and some projects develop into separate planned languages. Calling all of them “reforms” hides the decisive question: does the proposal use Esperanto's existing system, add an option beside it, or replace part of the common base?
The Fundamento protects that base from continual redesign. It does not ban discussion, new vocabulary, or creative language. It means that a writer cannot unilaterally remove an ending or redefine a correlative and still present the result as unmarked standard Esperanto.
Innovation is not automatically reform
A new word formed with ordinary roots and affixes extends expression without changing the grammar. So does a loan adapted to Esperanto morphology when a community establishes it.
La savteamo uzis dronon por foti la inunditan valon.
The rescue team used a drone to photograph the flooded valley.
La programo aŭtomate ĝisdatigas la vortaron ĉiun semajnon.
The program automatically updates the dictionary every week.
Neither sentence asks speakers to abandon noun -o, verb endings, agreement, or accusative -n. The vocabulary is newer than the Fundamento; the construction is ordinary Esperanto.
A parallel synonym can also arise without deleting the earlier form. The Fundamento's preface explicitly anticipates new expressions existing beside older ones. Whether the innovation is useful, conventional, or suitable for learners remains open to evidence.
La nova termino aperas apud la pli malnova esprimo; la aŭtoro klarigas ambaŭ ĉe la unua uzo.
The new term appears alongside the older expression; the author explains both at first use.
See The Fundamento and the Living Language for the underlying norm model.
A reform replaces part of the shared system
Proposals to abolish accusative marking, change the plural ending, remove agreement, redesign the correlative table, or replace the standard alphabet affect how existing sentences are formed or read. These are reforms, even if their proponents describe them as simplifications.
La propono forigus la finaĵon -n el ĉiuj rektaj objektoj kaj tiel ŝanĝus jam ekzistantajn frazojn.
The proposal would remove the ending -n from all direct objects and would thereby change already existing sentences.
Se ĉiu grupo samtempe ŝanĝus alian regulon, la komuna legebleco rapide malfortiĝus.
If every group changed a different rule at the same time, shared readability would quickly weaken.
The relevant cost is not only theoretical elegance. A systemic replacement affects books, teaching, search, speech recognition, and mutual predictability. A reform can have internally reasoned goals and still be nonstandard Esperanto.
“Nonstandard” describes status, not moral worth
A nonstandard proposal may be interesting, principled, playful, or socially important. The label tells learners that it is not part of the shared neutral norm. It should be specific: non-Fundamental but attested, experimental, community-specific, or contrary to the standard grammar are not synonyms.
The pronoun ri, for example, is a modern, attested, non-Fundamental form used by parts of the community. Using it does not require rewriting all personal-pronoun grammar. A proposal to replace every third-person pronoun with a completely new paradigm would be a broader reform.
En ĉi tiu artikolo la aŭtoro uzas ri kaj klarigas la elekton en redakta noto.
In this article the author uses ri and explains the choice in an editorial note.
That sentence documents usage without falsely calling ri either Fundamental or universally accepted. The dedicated page on Ri and Gender-Neutral Reference gives the full status and alternatives.
An Academy recommendation is another category. The Academy may recommend or officialize forms, but its own explanation of the Ninth Official Addition says that officialization is a strong recommendation and does not make a root original-Fundamental.
Technical input conventions are not spelling reform
The standard alphabet contains ĉ, ĝ, ĥ, ĵ, ŝ, ŭ. When technology once made those characters difficult, speakers used substitute sequences. The Fundamental h-system and the widespread x-system encode letters; they need not propose a new alphabet.
La arkivo konservas malnovajn mesaĝojn en anstataŭa skribsistemo, sed la moderna eldono montras la ĝustajn supersignojn.
The archive preserves old messages in a substitute writing system, but the modern edition displays the correct diacritics.
The Academy has explicitly distinguished a purely technical substitution from an attempted orthographic reform. Context and intent matter. Publishing bare substitute sequences as the permanent preferred alphabet would be a different claim from typing them so software can convert them.
Ĉu la sistemo aŭtomate konvertos la enigitan tekston al normala Unikoda Esperanto?
Will the system automatically convert the entered text to normal Unicode Esperanto?
For input details, see The X-System. In ordinary modern content, full Unicode is the clear default.
Ido is a separate planned language
Ido emerged from the reform crisis around 1907 and deliberately changed substantial parts of Esperanto's vocabulary, morphology, and orthography. It developed its own norms, literature, organizations, and speaker community. Historically related does not mean “regional Esperanto,” “bad Esperanto,” or a set of optional Esperanto endings.
Ido historie devenas de reformprojekto, sed hodiaŭ ĝi estas priskribenda kiel aparta planlingvo.
Ido historically derives from a reform project, but today it should be described as a separate planned language.
La preleganto komparis Esperanton kaj Idon, sed li ne miksis la du gramatikojn en unu ekzercaro.
The lecturer compared Esperanto and Ido but did not mix the two grammars in one workbook.
This neutral description avoids the polemical vocabulary historically attached to the split. One can study Ido on its own terms or compare the design choices. In an Esperanto lesson, however, Ido forms must be identified as Ido rather than offered as modern Esperanto variants.
Historical reform debate explains the stability principle
Before the Fundamento was adopted, substantial reform proposals were debated, including proposals associated with 1894. The 1905 Fundamento and Bulonja Declaration then established a stable common reference. The later Ido crisis demonstrated how design debate can become a language split once incompatible systems acquire communities.
La historia debato okazis antaŭ ol multaj nunaj komunikiloj ekzistis, sed ĝia centra demando restas aktuala: kiel novigi sen perdi komunan bazon?
The historical debate took place before many present-day media existed, but its central question remains current: how can one innovate without losing a common base?
Stability does not mean that every early preference won. Vocabulary expanded, meanings shifted, new genres appeared, and accepted alternatives developed. The crucial method was additive development: new resources did not invalidate the old corpus.
La nova esprimo povas iom post iom fariĝi pli ofta, sen ke la malnova teksto fariĝu nekomprenebla.
The new expression can gradually become more frequent without the old text becoming incomprehensible.
That backward readability is a practical value, not merely reverence for history.
Evaluate a proposal on several axes
Do not ask only whether a form is logical. Ask:
- Norm: Is it Fundamental, later official, accepted, experimental, or contrary to the shared grammar?
- Meaning: Does it fill a real gap or merely rename an existing distinction?
- Distribution: Who uses it, in which genres, and for how long?
- Transparency: Can an international reader infer it without private instructions?
- Compatibility: Does it preserve access to existing texts and communication?
La komisiono ne malakceptis la terminon nur pro ĝia noveco; ĝi ekzamenis ĝian signifon, formon, uzadon kaj rilaton al jam ekzistantaj vortoj.
The committee did not reject the term merely because of its novelty; it examined its meaning, form, use, and relation to already existing words.
A corpus answers attestation questions, not constitutional ones. An Academy act answers official-status questions, not whether every speaker has adopted the recommendation. A forum poll reveals the participating forum, not the entire language community.
Discuss reform without silently teaching it
When quoting experimental text, label it before readers encounter it and supply standard Esperanto if teaching is the goal. Do not place a reformed form in an ordinary example and leave learners to infer whether it is a typo.
La sekva citaĵo uzas eksperimentan gramatikon; post ĝi ni donas la saman enhavon en norma Esperanto.
The following quotation uses experimental grammar; after it we give the same content in standard Esperanto.
This editorial practice supports both intellectual openness and learner clarity. In historical scholarship, reproduce sources accurately. In a practical guide, keep the norm unmistakable.
Common Mistakes
1. Calling Ido a national or regional Esperanto dialect.
❌ Ido estas la Esperanto-dialekto de unu lando.
Incorrect: Ido is a separate planned language with its own history and norms.
✅ Ido ekestis el reformprojekto rilata al Esperanto kaj evoluis kiel aparta lingvo.
Ido arose from a reform project related to Esperanto and developed as a separate language.
2. Calling every new word a reform.
❌ Ĉiu vorto kreita post 1905 ŝanĝas la Fundamentan gramatikon.
Incorrect: vocabulary can expand through the existing productive system.
✅ Nova vorto povas uzi la ekzistantajn radikojn, afiksojn kaj finaĵojn sen reformi la gramatikon.
A new word can use the existing roots, affixes, and endings without reforming the grammar.
3. Applying a proposed loss of the accusative as neutral Esperanto.
❌ Mi legis la interesa artikolo hieraŭ.
Nonstandard as ordinary Esperanto: the direct object lacks required accusative agreement.
✅ Mi legis la interesan artikolon hieraŭ.
I read the interesting article yesterday.
4. Treating a recommendation as a rewrite of history.
❌ Se la Akademio oficialigas radikon, tiu radiko ĉiam troviĝis en la originala Fundamento.
Incorrect: later official status is distinct from original Fundamental status.
✅ Poste oficialigita radiko estas oficiala, sed ne pro tio originale Fundamenta.
A root officialized later is official but is not therefore originally Fundamental.
Key Takeaways
- Ordinary lexical innovation uses the existing system; reform replaces part of that system.
- Label non-Fundamental, accepted, experimental, and contrary-to-standard forms separately.
- Technical input encoding is not necessarily spelling reform, and Unicode remains the modern publication default.
- Ido is a historically related but separate planned language, not an Esperanto dialect.
