чётко

чётко is a common Russian adverb, usually meaning “clearly,” “precisely,” or “sharply.” In informal speech, it can also mean “cool,” “great,” “solid,” or “exactly right,” depending on tone and context.

It comes from чёткий, meaning “clear,” “distinct,” “precise,” or “sharp.” The slang-like approving sense developed from the idea that something is well organized, accurate, or done properly.

Common uses include:

• чётко объяснить — to explain clearly
• чётко по плану — exactly according to plan
• чётко! — Nice! / Great! / Exactly!
• всё чётко — everything is good / everything is in order

Related words: ясно (“clearly”), точно (“exactly”), отлично (“excellent”), and круто (“cool”). In casual Russian, чётко often sounds confident and approving.
