Documented Proof: How Language Authorities Settle the Fiercest Orthographic Debates
Historical documents, global dispatches, and theological declarations encounter precise mechanics when documenting papal successions and royal lineages. Print standards mandate the use of Roman numerals directly following the regnal name without intervening commas, hyphens, or periods, as seen in Juan Pablo II, Felipe VI, or Francisco. The orthographic complexity appears when writers must expand these titles into written words or formal speech.
Under established Spanish orthographic rules, regnal and dynastic numbers follow ordinal conventions from the first through the tenth iterations: primero (1st) through décimo (10th). Once a lineage crosses past ten, the convention switches completely to cardinal numerals:
| Regnal Title (Print) | Spoken / Expanded Form | Rule Category |
|---|---|---|
| Benedicto XVI | Benedicto dieciséis | Cardinal rule (Numbers > 10) |
| Alfonso X | Alfonso décimo | Ordinal rule (Numbers 1, 10) |
| León XIII | León trece | Cardinal rule (Numbers > 10) |
| Pío IX | Pío noveno | Ordinal rule (Numbers 1, 10) |
Journalists frequently err by writing Benedicto decimosexto, an archaic formulation that breaches modern formal writing standards. When ordinal expansion is required for historical consistency in titles below eleven, writers must preserve gender agreement with implicit underlying nouns, though papal figures remain universally masculine.
