set of rules
Usage Note
Reglamentación refers to a body of regulatory rules or the act of establishing them — broader than a single reglamento (regulation/rulebook). It is common in administrative and legal texts: reglamentación laboral (labour regulation), reglamentación sanitaria (health regulation). The accent on the final syllable is consistent with Spanish -ción nouns.
Examples
"La nueva reglamentación entró en vigor ayer."
Natural Translation
The new regulation came into force yesterday.
