I had always thought that “ładna” and “piękna” had the same meanings, but from the following sentence taken from “Kim ona jest?”, I guess that the former is lighter than the latter:
Czy ona jest ładna?
Tak, rzeczywiście jest bardzo ładna. Mogę nawet powiedzieć, że jest piękna.
Can anyone explain the difference? When I created the respective LingQs, I wrote the same translations for both…
