nainstalovali

Nainstalovali is the past tense form of the Czech verb nainstalovat, meaning “they installed” or “they have installed,” typically referring to the completion of an installation of software, hardware, or a system. The verb is perfective, used to describe a completed action, and past tense forms agree with the subject in gender and number; nainstalovali is used with masculine personal subjects.

Other past-tense forms of the same verb include nainstaloval (masculine singular), nainstalovala (feminine singular), nainstalovalo (neuter singular), nainstalovali (masculine plural), and nainstalovaly (feminine plural).

Etymology and usage notes: nainstalovat is formed from the root instalovat with the prefix na- to indicate completion and is the perfective counterpart to instalovat. The word draws on the Czech adaptation of the English term install, and is common in IT, engineering, and administrative contexts. Because it is a perfective verb, nainstalovali typically emphasizes that the installation was finished rather than ongoing.

Usage examples: Nainstalovali nový operační systém na všech počítačích. Společnost nainstalovala opravu na server. The form nainstalovali specifically marks a masculine plural subject; for other subjects, use the corresponding forms such as nainstalovali, nainstalovala, or nainstalovalo as appropriate.
