deduz

Deduz is the third-person singular present indicative form of the Portuguese verb deduzir. The verb deduzir, in turn, means to deduce (to infer a conclusion from the facts) or to deduct (to subtract an amount, such as in taxation or accounting). Deduzir derives from Latin deducere, meaning to lead down or derive. The word is used across Portuguese-speaking regions with both reasoning and financial senses.

Usage of deduz is common in logic, mathematics, law, and everyday speech when describing the act of inferring a conclusion from evidence. For example: Ele deduz a solução a partir das evidências. In financial and tax contexts, deduzir means to subtract allowable expenses from a base amount; for instance, a empresa pode deduzir despesas operacionais para calcular o lucro tributável. The nuance between deduction of information and deduction of costs is clear from context and accompanying nouns.

Conjugation notes: In the present indicative, the verb forms are eu deduzo, tu deduzes, ele/ela deduz, nós deduzimos, vós deduzis, eles/elas deduzem. The form deduz specifically corresponds to ele/ela and, in Brazilian Portuguese, often to você as the everyday second-person form. The related noun dedução refers to the act of deducing or to the deduction itself, while dedutível describes something that can be deducted.
