prichinu

Prichinu is the transliteration of the Cyrillic word причину, the accusative singular form of причина, meaning the reason or the cause in Russian and Ukrainian. In ordinary speech the term denotes the factor or motive that explains an event or decision. As a grammatical form, причину is used with transitive verbs that govern a direct object; for example, Я знаю причину (I know the reason) or Мы нашли причину проблемы (We found the cause of the problem).

In Slavic languages the noun причина belongs to a family of cognates for "cause" or "reason." Its use spans everyday language, journalism, and formal discourse, and it appears in a range of fixed expressions related to explanation, motive, or justification.

In philosophy, science, and logic, причина refers to a causal factor in events, and phrases such as причинно-следственная связь describe a cause-and-effect relationship. In legal or administrative contexts, the word may specify motives or grounds for actions, such as the reason for a decision or for a particular administrative measure.

Transliteration variants of prichinu may appear in texts written in Latin script or in language-learning materials, especially when illustrating grammatical forms or providing cross-language comparisons. The root concept remains the same across contexts: it denotes what explains why something happens.
