referió

Referió is a verb form in Spanish taken from the verb referir. It is used in the pretérito indefinido (simple past) to indicate that a subject mentioned, related, or reported something in a past moment. In narrative or reportive contexts, it can introduce information that was cited or recalled.

As a conjugated form, referir belongs to the group of stem-changing -ir verbs. In the past tense, it is used with a third-person singular subject (he, she, or it) or with singular nouns, such as "El informe referió varios puntos." The meaning conveyed by referió centers on directing attention to a point, a source, or a set of facts, rather than describing a direct action of touching or moving something.

Usage notes and nuance:

- Referió often appears in journalism, academic writing, and formal narration when summarizing what another person or document stated.

- It can be followed by a phrase introducing the referenced material, such as "referió datos," "referió testimonios," or "referió a estudios previos."

- The choice between referir and its past forms depends on the temporal reference (past vs. present) and the perspective of the narrator.

Etymology and related forms:

- Referir comes from Latin referre, with the re- prefix meaning back or again, combined with ferre, to bear or carry.

- Related forms include referring (referir in other tenses), referencia (reference), and referido (past participle or noun form in different contexts).
