To be very important in a process.
文化的背景
In Russian corporate environments, using 'играть ключевую роль' is a sign of high professional status. It is often used in 'отчёты' (reports) to justify budgets or praise departments. Russian scholars heavily use this phrase in 'диссертации' (theses). It is considered more academic than simply saying 'это важно'. In history books, specific battles or leaders are always described as playing a 'key role' in the victory of the Great Patriotic War, reinforcing a sense of destiny and structural importance. Journalists use this phrase to create a sense of urgency or significance in news headlines, especially regarding sanctions, technology, or celebrities.
Use the Perfective for Results

The 'Meaning' Trap
Never say 'играть значение'. This is the most famous mistake in Russian. It's either 'играть роль' or 'иметь значение'.
