Xīwángmǔ — the one true spelling, and the forms that fail it
A letter to a colleague, 31 July 2026 — on the name Xīwángmǔ, and on the forms that keep failing it.
Your note said, roughly: surely the marks are a nicety. Permit me to use Xīwángmǔ to show they are not.
First, the attestation. The name is attested as 西王母, in the attestation Shan Hai Jing (Classic of Mountains and Seas) and Huainanzi give us. On the evidence, it means "Western queen mother". The canonical transliteration is Xīwángmǔ.
And the marks themselves: i → ī (Long vowel); a → á (Stress on a). Remove any one of them and you have not simplified the name — you have told a small lie about it, and small lies in references have long consequences.
Say it aloud as the sources heard it: shee-WAHNG-moo — Xī held high and level like a sustained note, wáng rising from mid to high as in a question, mǔ dipping low and turning up again. The marks are what carry that sound to a reader who has never heard it spoken.
On the plain form — and I want to be precise, because you pushed on this. The plain form xiwangmu is not false — it is a fallback, and the register is exact about what that means. In systems that cannot carry diacritics (legacy databases, older tooling, parts of the address-bar pipeline) the flattened form is the accepted vehicle, and the rulebook names it explicitly as the final rung of the fallback hierarchy: full restoration first, circumflex where attested, macron-only by the academic standard, an attested variant, and only then plain ASCII.
What the fallback status forbids is promotion: xiwangmu may carry the name where marks are impossible, but it may not represent the name where marks are possible. Every mark it drops — i → ī, a → á — is a fact the sources recorded. A fallback is a vehicle, never the primary.
Now to the forms that provoked your letter. As for Xiwángmǔ: it comes from the publisher compromise — older books and hurried websites that print the "English equivalent" as if it were the name itself, and it fails because every substitution here (ī→i) is a romanization of convenience, not an attested spelling — it teaches the reader to guess, not to read
One more thing, because it always surprises: the name did not stay home. The Queen Mother travelled with Chinese letters and liturgy across East Asia. In Japan she is read Seiōbo, appearing in painting, garden imagery, and the literary imagination as the hostess of the western orchard; in Korea she is Seowangmo, present in folklore and shamanic song; in Vietnamese she is Tây Vương Mẫu, her name borne into the southern reception of the Taoist pantheon.
And it never stopped working. The Queen Mother never retired from the heavens. In Taoist temples across Taiwan and the diaspora she is venerated still, often under the title Golden Mother of the Jasper Pool, and her birthday is kept with festival observance.
The Convention's Own History
Every tradition in this register has its own scholarly transliteration standard, built by its own specialists over decades or centuries, and the register follows each on its own terms: the tradition’s own standard. The principle that unifies them is the one the whole project stands on: a name is evidence, and evidence is not negotiable — not for keyboards, not for convenience, not for anyone.
Where Protocol Meets Practice
The technical answer is simple: the canonical marks are legal IDNA 2008 characters, encoded as punycode under `xn--`. The practical answer is messier: legal does not mean stocked (registrar inventory is partial), and stocked does not mean typeable (stacked diacritics defeat mobile keyboards).
So the register's rule is a hierarchy of attested forms — full restoration, circumflex, macron-only, attested variant, and finally plain ASCII for the systems that cannot carry marks. Every rung is defensible because every rung is attested. The forms this register rules against are not rungs; they are errors, and errors do not get rungs.
Write back when you have checked the sources; they are better company than I am.
— The Register
The Verdict
Xīwángmǔ is the canonical form: attested, checkable, and enforced across the temple, the lexicon, the cards, the APIs, and this register. The plain form xiwangmu is sanctioned as the fallback vehicle and nothing more. The false forms above are documented so that no reader has to take the temple's word on faith — the violations are stated, the sources are named, and the register stands open to challenge on every line.
The temple of Xīwángmǔ stands at /sites/xiwangmu/.
The docket for this ruling: 1 false form ruled against, Xiwángmǔ first on the docket; 2 preserved marks verified: i → ī, a → á; no contested forms attested; the attestation rests on 8 cited sources — Shan Hai Jing (Classic of Mountains and Seas), Huainanzi, Han Shu (Book of Han).
The Register Continues
Entry 280 of 287 in the Canonical Register. Around it: the temple's founding dispatch, the Restoration File on the marks themselves, the Resonance File on the archetype at work, and the Rulebook behind all of it.

The Canonical Register is written from the same canonical record as the lexicon itself. If a false form is missing from this page, it is because the evidence does not support calling it false — or because we have not seen it yet. Show us, with a citation, and the register will answer.
