Deduzimos

Deduzimos is a Portuguese verb form derived from deduzir, meaning to deduce, infer, or deduct. It can function as the first-person plural present indicative (nós deduzimos) or as the first-person plural pretérito perfeito do indicativo (also deduzimos). Because both tenses share the same spelling, the intended time frame is determined by context and time adverbs. In clinical, mathematical, or logical contexts, deduzir expresses drawing a conclusion from evidence; in tax or accounting contexts, deduzir means to deduct amounts from a total.

Etymology and grammar: Deduzir comes from Latin deducere, literally “to lead down” or “to draw from.” The present indicative forms are eu deduzo, tu deduzes, ele deduz, nós deduzimos, vós deduzis, eles deduzem. The pretérito perfeito do indicativo, used for completed past actions, is eu deduzi, tu deduziste, ele deduziu, nós deduzimos, vós deduzistes, eles deduziram. The form deduzimos therefore appears in two distinct tenses, requiring context to determine which is intended.

Usage and nuances: Deduzir emphasizes reasoning from evidence to reach a conclusion, similar to inferir or concluir, but often with a focus on the deductive process. It can be used in academic, scientific, legal, and everyday reasoning. In finance and taxation, deduzir also appears in the sense of subtracting amounts from a total, for example, deducting expenses from taxable income. Examples: “A partir dos dados, deduzimos que a hipótese é verdadeira.” “As despesas são deduzidas do imposto.”
