déduis

Déduis is the first-person singular present indicative form of the French verb déduire. Déduire means to deduce, infer, or derive a conclusion from information, evidence, or premises. The sense is to arrive at a result by reasoning rather than by direct observation. The verb is commonly used in everyday language, scientific discussion, and formal analysis.

Etymology and usage context: déduire comes from Latin deducere, meaning to lead down or to derive. In French, it is used with the preposition de to indicate the source of the deduction, as in déduire qch de qch. The construction en déduire que is frequent for presenting a conclusion derived from prior statements or data. The noun form is déduction, referring to the act or result of deducing, and the related adjective déductif is used in formal or mathematical contexts.

Conjugation and grammar: déduire is a regular -ire verb with the present tense forms: je déduis, tu déduis, il déduit, nous déduisons, vous déduisez, ils déduisent. The past participle is déduit, used with auxiliary avoir in compound tenses (par exemple, j’ai déduit). The construction déduire qch de qch is common, as is en déduire qch (to deduce something).

Relation to synonyms and nuance: déduire is often close to inférer and conclure. Inférer emphasizes logical inference from premises, while déduire stresses deriving a specific conclusion from evidence. Conclure signals arriving at a final decision or judgment, which may be broader than a single deduction.

Example: On peut en déduire que les données restent insuffisantes pour conclure définitivement. Je déduis une erreur de ce raisonnement à partir des chiffres.
