vigorou

Vigorou is the past tense form of the Portuguese verb vigorar. The verb vigorar means to be in force, to have legal effect, or to prevail. In formal writing and reporting, vigorou is used to indicate that a rule, law, contract, or regulation was active during a certain period in the past and then either expired, was amended, or replaced.

Common contexts include legislative acts, regulatory frameworks, and treaties. For example: "A lei vigorou de 2005 a 2015" (The law was in effect from 2005 to 2015). Another example: "O acordo vigorou até a renegociação." In news reporting, vigorou frequently appears with dates to denote the period during which the rules applied.

Pronunciation and semantics: Vigorou is a third-person singular preterite form; it does not function as a noun. It shares its root with vigor and vigoroso, which refer to strength and liveliness, but vigorou specifically denotes force or validity in the past.

Etymology: The verb vigorar comes from Latin roots associated with vigor and life, passing into Portuguese with the sense of being effective or in force.
