vyvinuli

Vyvinuli is a Czech verb form that corresponds to the past tense, masculine plural, of the perfective verb vyvinout, meaning “they developed” or “they have developed.” It is used to describe a completed act of development carried out by a group or by multiple subjects.

Etymology and morphology: Vyvinout is formed with the prefix vy- attached to a root related to vývin, the noun for development or evolution. The ending -li marks masculine plural past tense in this verb class. Related forms include vyvinul (he developed), vyvinula (she developed), vyvinuly (they developed in feminine plural), and vyvinula (she developed). The form vyvinuli specifically signals a masculine or mixed-gender plural subject.

Usage: Vyvinuli appears in formal or technical registers, such as scientific, technological, or historical texts, to report a completed development by a group. For example, "Tři týmy vyvinuli nový prototyp." It is not used as a noun; for noun usage related to development, Czech has the nouns vývoj and vývin, which refer to the process or result of development more generally.

Notes: The verb pair vyvinout (perfective) and vyvíjet (imperfective) cover development actions from completed and ongoing aspects, respectively. Vyvinuli is appropriate when the context involves a past, completed development by multiple agents. See also vývoj and vývin for related noun forms describing development as a concept.
