coexistiram

Coexistiram is the third-person plural pretérito perfeito do indicativo of the Portuguese verb coexistir, meaning that two or more entities existed at the same time in the past. The form is used to describe historical periods, events, or situations where different elements shared the same space, time, or context.

Etymology and form: Coexistir is built from the prefix co- (together) combined with existir (to exist), which derives from Latin existere. Coexistiram follows the regular conjugation pattern of regular -ir verbs in the pretérito perfeito: eu coexisti, tu coexististe, ele coexistiu, nós coexistimos, vós coexististes, eles coexistiram.

Usage notes: The expression highlights temporal or spatial overlap rather than a value judgment about harmony or conflict. It can refer to species, cultures, ideas, regimes, or technologies that were present simultaneously. In scholarly writing, it often appears in historical, sociological, or ecological analyses to indicate coexistence dynamics or to set the context for interactions between different subjects.

Examples:

- As espécies coexistiram no mesmo ecossistema por milhares de anos.

- Diversas tradições religiosas coexistiram na região durante o período medieval.
