Projevovat

Projevovat is a Czech imperfective verb meaning to express, demonstrate, or show something, such as feelings, opinions, or qualities. It can refer to intentionally expressing something (projevovat náklonnost, projevovat zájem) as well as to the appearance or manifestation of features or symptoms (příznaky se projevují). In the reflexive form projevovat se, the verb describes how something naturally manifests or becomes evident.

Etymology and related forms: Projevovat derives from the noun projev, meaning expression or manifestation, with the common Slavic verbal suffix. The imperfective aspect contrasts with the perfective projection projevit, which denotes a completed or one-time act of expressing or revealing.

Usage and constructions: Projevovat is typically transitive with a direct object expressing what is shown, or used with se in the intransitive sense projevovat se to indicate manifestation or appearance. Common collocations include projevovat zájem, projevovat sympatie, projevovat odvahu, and projevovat agresivitu. The perfective projevit is used when the act is viewed as a single, completed instance (e.g., Projevil svůj zájem o spolupráci).

Examples:

- Projevuje zájem o nový projekt. (He shows interest in the new project.)

- Příznaky se projevují po několika dnech. (The symptoms appear after several days.)

- Projevil svůj zájem o spolupráci. (He expressed his interest in collaborating.)

- Chování se projevuje agresivitou. (The behavior manifests aggression.)
