What does “krok po kroku” mean, and how does the pattern work in Polish?

This pancake recipe promises to walk you through it krok po kroku — “step by step.” The phrase repeats the same noun, krok (“step”), with po in between, and that little formula — noun + po + the same noun — is how Polish builds a whole family of “one-by-one” expressions.

Swap in a different noun and the pattern still works: dzień po dniu is “day by day,” rok po roku is “year by year,” kropla po kropli is “drop by drop.” Once you notice po repeating a noun like this, you can build new ones on the fly — useful well beyond the kitchen.
