resolvedestablishedexact word
Is the x of rēx an inherited single stem consonant?
No. In the Latin nominative, stem rēg- combines with -s; g devoices to k before s and the /ks/ cluster is spelled x. The genitive rēgis preserves visible g.
resolvedestablishedexact word
Did genitive rēgis historically produce nominative rēx?
No. Rēx and rēgis are inflected forms in one paradigm. The graph uses the genitive to expose the stem, not as a chronological parent word.
resolvedestablishedexact word
Did Latin rēx produce Old Irish rí or Gaulish -rīx?
No. The reviewed comparative sources treat the Latin and Celtic forms as inherited cognates in separate Italic and Celtic branches; Celtic raises inherited *ē to *ī.
resolvedestablishedexact word
Did royal and regal enter English through one identical route?
No. Both descend from Latin rēgālis, but royal crosses through Anglo-French roial or real while regal has Old French, Anglo-French, and direct-Latin transmission reported by different authorities.
