vyvíjali

Vyvíjali is a Czech verb form derived from vyvíjet, meaning to develop or to evolve. It functions as a past-tense form used with plural subjects, indicating that a group carried out development in the past or was in the process of developing something. Because vyvíjet is imperfective, vyvíjali can express ongoing or repeated development in the past, depending on context.

In Czech, past tense forms reflect both number and gender. Vyvíjali is typically associated with masculine or mixed-gender plural subjects; feminine plural would use a different ending, such as vyvíjely, and neuter forms like vyvíjelo exist for singular neuter usage.

Etymology and cognates: The verb vyvíjet is built from the prefix vy- and the noun vývoj (development), reflecting the concept of progress or change. Related terms appear in other Slavic languages with analogous meanings, though cognate forms are not always direct equivalents.

Usage: Vyvíjali appears in historical narratives, scientific writing, journalism, and fiction to describe groups of people, organizations, or entities developing projects, technologies, or ideas. Example usage in English: The researchers were developing a new drug. In Czech, the equivalent would typically be rendered using vyvíjali, given a plural subject and an appropriate context.
