Breakdown of После дождя на тротуаре скользко, так что иди осторожнее.
Questions & Answers about После дождя на тротуаре скользко, так что иди осторожнее.
Because после requires the genitive case.
- дождь (nom.) → дождя (gen.)
So после дождя literally means after (the) rain.
Because на + “location/where?” takes the prepositional case.
- тротуар (base form) → на тротуаре = on the sidewalk / on the pavement (location)
If you were talking about motion onto the sidewalk (“where to?”), you’d use accusative: на тротуар.
Скользко here is a category of state word (often taught as a “predicative” or “state word”), used in impersonal sentences. It functions like “(it is) slippery.”
You’re not describing a noun directly (like скользкий тротуар = “a slippery sidewalk”); you’re stating a general condition: (там) скользко = “it’s slippery (there).”
