complementaram

Complementaram is the third-person plural pretérito perfeito (simple past) indicative form of the Portuguese verb complementar. It means “they complemented” or “they supplemented” and is used to describe actions completed in the past that add to something or make it complete. The form is regular for -ar verbs: the infinitive complementar becomes complementaram in the past tense when conjugated for they.

Etymology and meaning: the verb derives from the Latin root complementare, related to completo or complemento, reflecting the idea of making something complete or adding to it. In usage, complementar can refer to adding information, components, or features to enhance a project, argument, dataset, or object.

Usage notes: complementaram appears in both European and Brazilian Portuguese with the same grammatical meaning and construction. It is common in narrative and descriptive contexts when describing past activities that completed or enhanced something. It can be used across disciplines, including journalism, academia, business, and daily language.

Examples:

- Eles complementaram o relatório com dados adicionais.

- As peças complementaram o design da obra.

- Os resultados complementaram as hipóteses formuladas no início do estudo.

Related forms: complementar (infinitive), complemento (noun meaning “complement”), complementação (nominal form related to the act of complementing). The tense can be contrasted with presente (complementam) and pretérito perfeito simples for diferentes sujeitos or times.
