vigorar

Vigorar is a verb used in Portuguese (also found in Galician) with two primary senses. The first refers to regaining or increasing vigor, vitality, or energy, usually applied to people, animals, or plants after a period of weakness or illness. The second sense is to be in effect or in force, particularly regarding laws, regulations, orders, or provisions.

Etymology: The term derives from vigor, itself from Latin vigor, meaning strength or liveliness, augmented with the infinitive suffix -ar.

Usage notes: In everyday language, vigorar tends to describe a return to health or vitality: "o atleta voltou a vigorar após o treinamento intenso." In legal and administrative contexts, vigorar is used to indicate that a rule or law has taken effect or remains in force: "a nova lei vigorou no início do ano" or "a lei está em vigor." The common idiom "em vigor" means currently in effect, while "vigência" denotes the period during which something remains in force. The term has stronger usage in Brazilian Portuguese; European Portuguese often prefers "estar em vigor" instead of vigorar, especially in formal contexts.

Conjugation: Vigorar is a regular -ar verb, and its conjugation follows standard patterns for -ar verbs. Tenses align with typical -ar verbs, with present tense forms and past tenses used in both senses.
