inferiu

Inferiu is the third-person singular form of the Portuguese verb inferir, used in the pretérito perfeito do indicativo. It indicates that a subject drew a conclusion or inferred something from evidence in the past. The form is common in written and formal contexts.

Etymology and form: inferir comes from Latin through the evolution of the prefix in- and the root ferre, related to bringing in or drawing conclusions. The verb overall belongs to regular -ir verbs in its conjugation pattern. Key related forms include: eu inferi, tu inferiste, ele inferiu, nós inferimos, vós inferistes, eles inferiram; the infinitive is inferir and the present tense infere/inferes/inferimos, depending on the subject.

Usage: Inferir is used to express logical deduction based on available data or clues. It often appears in scientific, analytical, or argumentative writing. It is distinct from concluir (to conclude) in that inferir emphasizes the inferential process, while concluir emphasizes the final decision, and deduzir focuses on deduction from premises.

Examples: O pesquisador inferiu que a variável X influencia Y a partir dos dados. Ela inferiu a intenção do autor a partir de pistas no texto.
