diminuiu

Diminuiu is a Portuguese verb form meaning "decreased" or "has decreased." It is the third-person singular preterite indicative form of diminuir, the verb that means to decrease or to diminish. The form is used to describe a completed decrease in the past, typically with a singular subject such as o preço, o número, or a single quantity.

In usage, diminuiu appears in statements about past changes in numbers, amounts, or intensity. For example, "O preço diminuiu" (The price decreased) or "O número de casos diminuiu" (The number of cases decreased). It is common in journalism, statistics, and everyday speech when reporting past trends or outcomes.

Conjugation and related forms follow the standard pattern for regular -ir verbs in the preterite. The infinitive is diminuir; the participle is diminuído; the present participle is diminuindo. The word also appears in compound tenses with auxiliary verbs, such as "tem diminuído" (has decreased) or "vai diminuir" (will decrease), depending on the temporal reference.

Etymology traces diminuiu to diminuir, from Latin diminutus or diminere, built from the root minus meaning "less." Related terms include diminuir (to decrease), diminuição (decrease, diminishment), and diminuído (decreased, past participle). Synonyms in Portuguese include reduzir and abaixar, used in slightly different contexts.

Overall, diminuiu is a common, neutral term in Portuguese for recording a completed reduction in quantity or intensity in the past.
