refinó

Refinó is the third-person singular preterite (pretérito perfecto simple) form of the Spanish verb refinar. It corresponds to "he refined," "she refined," or, in formal address, "you refined" (usted). The accent on the final syllable marks the stress pattern typical of regular -ar verbs in the preterite. The verb refinar means to purify, to improve quality, or to distill, depending on context; thus refinó can refer to refining metals, refining sugar or oil, or refining techniques, processes, or arguments.

The subject of refinó is typically a person or organization that performed a past action of refining. Examples: "El equipo refinó su estrategia tras las derrotas." "La refinería refinó la producción de combustible." "Ella refinó su técnica de pintura." "Usted refinó el procedimiento para reducir los costos." In each case, the action is completed in the past.

Notes: refinó should not be confused with refino (noun meaning refinery or refinement) or refinado (adjective meaning refined). Related terms include refinar (infinitive), refinamiento (refinement), and refino (noun). Refinó, as a single verb form, appears only within finite conjugation and requires a subject in the sentence to convey who performed the action.
