"Niespodzianka!"

Translation: Surprise!

[Kulink]

How does this break down? What is spodzianka?

[mihxal]

Nothing. "Spodziewać się" means "expect". Also "spodziewany" = "expected" so "niespoodzianka" = "something not expected".

It always amazes me how Polish has these instances of huge multi syllabic words for much shorter ones in other languages.

Blue...bleu...blau...niebieski for example
