Projevují

Projevují is the third-person plural present tense form of the Czech verb projevovat, meaning to express, to show, or to manifest. It is also used in reflexive form projevovat se, meaning to reveal or to manifest oneself. The form indicates that subjects (they) are currently expressing or displaying something, such as feelings, opinions, symptoms, or observable phenomena.

Grammatically, projevují belongs to the imperfective aspect, describing ongoing or repeated actions in the present. It is conjugated from the stem projev- with the standard third-person plural ending -ují. The perfective counterpart is projeví (or a form such as projeví se in reflexive usage) and is used for a completed or future moment of showing or manifesting.

Usage notes, meanings, and typical contexts include: expressing attitudes or preferences (projevují zájem), displaying symptoms or characteristics (příznaky se projevují), or demonstrating behavior in a situation (jeho chování se projevuje). In scientific or formal writing, it can describe observable data patterns (data projevují trend) or conclusions that emerge from evidence. In everyday Czech, it often appears with objects or clauses to specify what is being shown or expressed.

Etymology traces projevovat to the noun projev, meaning speech, statement, or manifestation, from which the verb extends the sense of making something apparent. Related forms include projevit (to reveal, to show — often perfective) and projevovat se (to reveal oneself or to manifest).
