  What it means

  Literally “at least” (from “co” + the superlative “najmniej,” meaning “what is least”). The phrase sets a minimum — it states that the quantity, degree, or time involved is no less than a certain value, and possibly more. For example: “Czekałem co najmniej godzinę” (I waited at least an hour) or “To kosztuje co najmniej tysiąc złotych” (That costs at least a thousand złoty). It is a very common quantifying adverb used in both speech and writing. Its opposite is “co najwyżej” (at most).

  Vocabulary

  • co — what (here a fixed part of a frozen phrase)
  • najmniej — least (superlative of mało — little/few)
  • co najmniej — at least (minimum value)
  • co najwyżej — at most (maximum value — the paired opposite)
  • przynajmniej — at least (close synonym, slightly more emphatic in spoken Polish)

  Grammar note

  "Co najmniej" is a frozen adverbial phrase — the "co" here is not a relative pronoun but a fixed particle forming the phrase. It does not change form and functions purely as a quantifier modifying numbers, durations, or amounts. Compare with "przynajmniej," which is a single-word synonym; both are grammatically interchangeable in most contexts, though "przynajmniej" can also carry a concessive meaning ("at least he tried") that "co najmniej" cannot.

  Cultural context

  The phrase is stylistically neutral and extremely frequent in everyday Polish at all levels — conversation, news, academic writing, and legal language. It is the standard way to express a minimum boundary on a number or quantity, just as "at least" functions in English. Learners sometimes confuse "co najmniej" (at least, in terms of quantity) with "przynajmniej" (at least, in a consolatory sense); in practice both are widely used and often interchangeable.
