Adapting language for different purposes (e.g., formal/informal)

Candidates must demonstrate precise control over sociolinguistic register, distinguishing effectively between informal (tú/vosotros) and formal (usted/ustedes) modes of address. Assessment focuses on the grammatical consistency of verb morphology and possessive adjectives, alongside the selection of vocabulary appropriate to the social hierarchy of the interlocutor. Mastery encompasses the ability to adapt tone for specific purposes, such as professional correspondence, service interactions, or peer-to-peer dialogue, reflecting the cultural norms of the target language community.
