Questions & Answers about Oni wciąż czekają na pociąg.

What does wciąż mean, and how does it compare to synonyms like ciągle or nadal?

wciąż means “still” in the sense of “continuing up to now.”

• ciągle also means “continuously” or “again and again,” often with a slightly more repetitive nuance.
• nadal is more formal, meaning “still” or “any longer.”
  In everyday speech you can usually swap wciąż and ciągle without changing the basic meaning:
  • Oni wciąż czekają na pociąg.
  • Oni ciągle czekają na pociąg.
  Using nadal:
  • Oni nadal czekają na pociąg.
  All three are correct, but nadal sounds a bit more bookish.
