The register rules: Tiāndì

A name is a chain of evidence. Tiāndì is intact; the forms below are where the chain broke. The register records each break, and why — and it is equally precise about what the plain form may legitimately do.

At a Glance

• Canonical form: Tiāndì
• Original script: 天地
• Pantheon: Chinese
• Convention: pinyin with tone marks — tones shown, ǖ kept distinct from u
• False forms on record: 1
• Contested forms: none attested
• Series: The Canonical Register, No. 243 of 271

The Canonical Form

The name is attested as 天地, as I Ching (Yijing) and Laozi, Daodejing preserve it. On the evidence, it means "Heaven and Earth; the natural order of the cosmos". The canonical transliteration is Tiāndì.

Every mark is evidence, and every piece of evidence is checkable:

• a → ā — Macron: first tone: the vowel length, as the sources give it.
• i → ì — Grave: fourth tone: the stress position, as the sources give it.

Where the Flattened Form Stands

The plain form tiandi 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: tiandi may carry the name where marks are impossible, but it may not represent the name where marks are possible. Every mark it drops — a → ā, i → ì — is a fact the sources recorded. A fallback is a vehicle, never the primary.

The Register of False Forms

These are the forms the register rules against. None of them is attacked as taste; each is shown to break a mark the evidence sets down.

False form 1: Tiandi

Origin: the publisher compromise — older books and hurried websites that print the "English equivalent" as if it were the name itself.

Violation: every substitution here (ā→a, ì→i) is a romanization of convenience, not an attested spelling — it teaches the reader to guess, not to read.

The Contested Forms

No alternate form of this name carries documented scholarly support in the lexicon's record. The convention here — pinyin with tone marks — tones shown, ǖ kept distinct from u — produces exactly one defensible transliteration: Tiāndì. Forms that differ from it are not contested; they are simply wrong.

What the Address Bar Allows

IDNA 2008 permits the letters these restorations use — macrons, acutes, underdots, thorn, ogonek, the lot — and the DNS carries them as punycode (`xn--` labels). Two honest constraints remain. First, registrar inventory: the protocol permits a character; the registrar's stock decides whether the exact domain can be bought today. Second, combined marks: forms like Apṓllōn (acute stacked on a macron) are philologically ideal yet effectively untypeable on phones and unsupported across much of the registration system.

That is why the rulebook keeps a fallback hierarchy — full restoration first, then the circumflex when the source carries one, then the macron-only academic standard, then an attested variant, and only as a last resort the plain ASCII form. Every step down the ladder is still defensible; nothing on the ladder is a wrong mark. A fallback is a choice among attested forms. A false form is not on the ladder at all.

The Verdict

Tiāndì is the canonical form: attested, checkable, and enforced across the temple, the lexicon, the cards, the APIs, and this register. The plain form tiandi 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 Register Continues

This is one of 271 entries in the Canonical Register — the authoritative reference for every flagship temple. The temple's founding dispatch tells the name's story; its Restoration File details the marks; its Resonance File reads the archetype into the industries. The blog index holds the whole archive, and the Rulebook states the convention this register enforces.

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.
