supuso

Supuso is the third-person singular preterite tense of the Spanish verb suponer, meaning to suppose or to assume. It is used in narrative or reported speech to indicate that someone concluded or inferred something in the past, often based on reasoning or incomplete information rather than direct evidence. For example, “Ella supuso que llegaríamos tarde” translates as “She assumed that we would arrive late.”

Etymology and form: Suponer derives from Latin supponere, from sub- meaning under and ponere meaning to place. The preterite form supuso corresponds to the past-time reference of “he/she/you (formal) assumed.” The verb participates in the regular preterite system of suponer, with other past forms including supuse, supusiste, supusimos, supusisteis, and supusieron, depending on person and number.

Usage notes: Supuso tends to convey a past inference, hypothesis, or assumption rather than a confirmed fact. It contrasts with verbs like creer or pensar, which express belief or thought without necessarily implying a concluded inference. In dialogue or narrative, supuso can help recount what a speaker believed at a specific past moment.

See also: The corresponding English translation is generally “assumed” or “supposed.” In contemporary Spanish, other past tenses of suponer (such as supo, supiste, supusieron) are used to reflect different subjects and times of past action.
